Thanks, I have watched several videos to get that while I always was feeling I can't get the thing, but I got the main idea clearly now...

[@pilotjim4595]

Good presentation, thanks. You can also use a DPDT on-on-on switch as a SP3T switch by placing a simple jumper on it. This is what I am doing on my airplane instrument panel. I want to send one signal to three different components one at a time.

[@simplyput2796]

Electronics goes from "cool" to "fun" when you get to start doing creative things like that. It's like we get to control reality a little bit. Object doesn't do the thing we want? So we make it do it anyway!

[@kilatonstudios5227]

This helped immensely with my research into a new project and hobby. Thank you. For the DPDT does this mean it could run circuit one on, circuit two on, then both on and both off all in a single switch with four positions? I am looking and linking two motor sets together to run as i have asked above so I can do a one or the either, neither both scenario. Just wanted to make sure i under stand correctly

[@zfm1097]

The DPDT switch you didn't know what it's for (at 8:00) is an ON-ON-ON switch. I'm using one to hopefully connect a (noise-cancelling) dummy coil inside my guitar, but I need bypass & phase reverse options (because my pickups also have phase-reverse switches). So up & down positions offer coil in two phases, while the middle offers bypass coil option.

[@pakvanjdam]

love the end haha :D hope you found something to press :D

[@KetilDuna]

dpdt is nice for swapping phase. A and B inputs, and connected diagonally to E and F - output on C and D. The mysterious third connection type would then short the outputs to one of the inputs, which might or might not be handy..

[@raviankita1]

Cool video.Thanks.

[@donaldsteele6276]

Hey I am wiring 1 linear actuator to a single axis solar tracker using DPDT RELAY 30 amp the actuator needs to be wired to reverse the pole to lower and reverse the other way to push up . So the center would be to the actuator and the other two side are wired to my battery bank 1 pair could be pos and neg and second pair neg then pos and 7 and 8 pin to tracker and when it sends the reverse poles to the relay it will switch back and forth between the 2 pole settings giving the desired up and down needed?

[@coolklick]

HI good lesson, can we use KDC4 in place of DPDT ?

[@what2be970]

Good explanations and examples in this video except for when it came to DPDT. You said that you couldn't think of a use for one so Ill give you one. In my boat, I have 2 tanks, but 1 gauge. I need to switch between tanks by providing a 12v+ to the tank valve while also switching the signal from the tank's sending unit to the gauge. Using a DPDT works perfectly in this case.

[@mikejones-vd3fg]

Switches are electrical components that allow or interrupt the flow of current in an electrical circuit. There are several types of switches, which can be classified based on the number of contacts they have, the number of positions they can take, and the number of circuits they can control. SPST (Single Pole, Single Throw) switch has one input and one output and can control a single circuit. It is either in the "on" or "off" position. SPDT (Single Pole, Double Throw) switch has one input and two outputs. It can switch between two different circuits and has three positions: "on" for one circuit, "on" for the other circuit, and "off". DPST (Double Pole, Single Throw) switch has two inputs and two outputs and can control two circuits independently. It is either in the "on" or "off" position for both circuits. DPDT (Double Pole, Double Throw) switch has two inputs and four outputs and can control two circuits and switch between two different connections. It has six positions: "on" for both circuits, "on" for one circuit and "off" for the other, and so on. In simple terms, switches control the flow of electrical current in a circuit by connecting or disconnecting components. The type of switch you use depends on the number of circuits and connections you need to control. --- Chatgpt's repsonse after literally typing in the title of this video into it.

[@dane5547]

Flipping the polarity is what I'm doing however I would like to get rid of my Omron G5-2 DPDT that I use to change power polarity to a device. What I'd like to do is construct a SSR DPDT. However, I'm finding this rather challenging. I've spent many hours with little success. Any suggestions.

[@larryroyovitz7829]

Question: If you wanted a 120v inverter to receive power from either the mains, OR a generator, you'd need a DPDT switch as a transfer switch, correct? Given that it's 120v (not 240v) you would use both poles - one for hot, and one for neutral, correct? This would feed either the hot and neutral from the panel, or the hot and neutral from the generator, or both off.

[@ryanlindo7489]

Hi nice detailesd video. I would like to know if the SPDT switch can be used in switching the power supply of my rechargeable fan from battery to electric and vice versa? I am planning to add an electric power supply option to my rechargeable fan while maintaining the battery option in operation. I'd like to have the option to switch to two different power supplies from time to time. Thanks in advance.

[@stewartmcminn7773]

Very useful thank you, I'm guessing the DPDT with 2 separate circuits can be 2 separate voltages right? Say a 12v and a 9v

[@umpy3152]

I'm hoping you can help me out. I have two old troy bily tractors that are very similar except one has a cruise control option. The toggle for the cruise control is a three position with the bottom being off, middle on and top momentary on. The way it works is, when you press the forward peddle to a desired speed, you press the top which is momentary, that locks a magnetic coil on the peddle shaft and holds it in position. This is wired to a latching relay and when the brake is pressed, it shuts the power off for the coil and remains off till the top momentary which is marked reset is pressed again. I made a cruise control for the tractor that didn't have one out of an ac compressor clutch coil and was able to get the correct switch and relay used online. My problem is with the switches which are obsolete and getting harder to find anywhere. I already had one switch go bad but luckily was able to find one. The switch has no identifiable marks or numbers so I don't have anyway to search it other than by description which offers no results. Have you ever seen such a switch? Like I said, down is off, middle on and top momentary (reset) and springs back to middle on. This switch has four pins on the back. Any info will be greatly appreciated. Thanks.

[@stevez4272]

The DPDT 3-way ON-On-On can be used for 3 different capacitors. In my case, I'm going to use it on the tone control of a guitar to be able to dial in a wider range of frequencies.

[@bigpowerhouse11]

Can you explain if both SPDT examples(on/off/on and on/on) can be interchangeable in a simple circuit? For example; to switch a low beam and high beam.

[@jhoughjr1]

I got a bs ee but don’t recall much about switches. Should be a fun review

The final DPDT relay functions as a less efficient H-bridge for reversing, coasting, or braking DC motors.

[@leodannyportal]

Hello, I have a 20 AMP double pole switch that works as follows: Its a Light switch in a guest bedroom with a Neutral (on the Top Left), Black Hot wire (on the Top Right) and Red Cable (on the Bottom Right). This Bottom right cable is only HOT when the master bedroom light switch is turned on). The Bottom Right terminal is blank. The house was built in the 20's and this setup I am told was used as security feature to turn on lots of bedroom ceiling lights from one dedicated switch in the master bedroom. When the master bedroom switch is in the ON and the Red Cable is hot the guest bedroom light switch remains on thereby keeping the ceiling lights illuminated. Can you describe how many throws it has? Thank you!

[@ananasmann8611]

I think the last one mostly gets used as an on-on-on switch. If D and E get shorted, C connects to either A, B or F

[@simplyput2796]

Oh wow, that's deviously cool. That's a great way to do a 3-to-1 switch.

[@cntryboygeetar]

Question, so let's say you had a drill each switch gives forward and reverse. What switch is this that changes polarity. One step further what switch that is auto would alternate the polarity of such drill so turn right turn left turn right ect. without actually hitting a switch at all for this alternation to occur. I'm a Noob just starting out trying to learn each thing. Thank you for the great video guides, a lot of help.

Hello, I enjoyed your show. Can you help me? I have a 2”Haibel SPDT on off on 3 position 4 pin switch. The pins are numbered on top left as 8,2,3 and on the right 7. I put 7 as ground. 8 as power in. 2 goes to relay switch 86 to device, 3 to another device. All is well. However, I would prefer the device to be controlled by pin 2, and the relay by pin 3. This makes their operation more senseful. However, in this configuration the devices do not work. Could you kindly tell me how to solve this problem?

[@lcrazyjeff]

great presentation but what in the world happened to your headset?!

[@najiaa0a]

Please help I have a load (timer) and want to control from 2 different places.1) if both switches are on, then load is to be on. 2) if either of the switches is off, the load should be off. 3) if either of the two switches is on, then the load should be on. The load is a timer that need to be powered off before it can be powered on. So the off is should be the priority. Thanks

[@Vgp-rp4iu]

Ok so I want to put a switch on my riding mower so I can turn the lights on and off. They are on all the time right now when it's running. Would SPDT switch be the best option? Just cut the wire between the lights and battery and put the switch between?

[@simplyput2796]

If it's two wires, you'd only need to cut one and put a simple SPST in there (could even use a light switch from the hardware store and bolt it onto the frame), because you're just trying to break/connect the circuit. If the two lights have separate wires (two each, four total wires), you probably could just tie together either both high or both low and do the same thing, but if for whatever reason they need to remain separate (I can't imagine why, but just in case) then you'd get a DPST, which is two completely separate connections but both controlled by the same switch (both on or both off).

[@Vgp-rp4iu]

@@simplyput2796 awesome thanks. From what I see there is 2 wires coming from the battery I'm assuming then there is a Y that just splits off to the other light. So that simple setup would just need an SPST right? Basically cut one of the wires (before the Y) and add the switch? Would it matter what wire I cut? And also as far as switches go I have a question. I would like a switch that lights up (preferably lit weather the lights are on or off or even one that lights up when I switch it on) but the only ones I can find that light up have 3 poles. Does that matter? Like do I have to use the 3rd pole? Sorry for all the questions I'm just not very good with wiring lol. I suppose just a basic 2 pole attached to one of the wires would be fine I just like the light up switches better. (more options to choose from as well it seems)

[@simplyput2796]

If you can find a Y, just cut either wire before the Y and put the switch in. There couldn't possibly be enough watts going through to a couple lights to do damage to a simple switch. As to the light-up switches, check the datasheet or infosheet and there will be a wiring diagram to tell you what the poles are for. If you get the switch from the hardware store, there might be a little folded-up piece of paper in it to tell you what to do.

[@d.j.peters]

Happy new year, one important property of switches are missing MBB = "make before break" and BBM = "break before make"

[@CandyGramForMongo_]

[@simplyput2796]

I can well imagine, but reality is so messy with switch bouncing and everything, that electronics absolutely should be engineered to withstand such things when possible, even if it's just a fuse.

[@simplyput2796]

Well, that's a new concept for me, but obvious now that you mentioned it and I looked it up. And I think I'll have to just keep on going as if it didn't exist and plan for the worst, because I haven't even found documentation for many switches that even states which it is! Although now I have an idea to do a video on using a circuit or an oscilloscope to check it...

[@dtusllitg2132]

Wouldn't you please explain how to use and wire a DPDT switch to a microcontroller to detect ON-OFF-ON events?

[@garyexgrunt7902]

What do I need to wire up 2 different signals so I can use either s-stops to to stop 2 different circuits. I hope I explained what I need to do. Any help would be helpful.

[@simplyput2796]

Perhaps you could explain in more detail. Are you trying to stop each circuit independently, or both together? If you want both to be open or both to be closed simultaneously, you want a DPST switch. Otherwise, you'd just have two separate switches.

[@garyexgrunt7902]

I want either of the e-stops to stop both of the circuit at the same time as I am working on a milling machine and I have one e-stop that is on the machine and another on the breakout board. The one on the machine just stops the spindle and the one on the breakout board stops the bed. I need it all to stop if either e-stop is pushed. I hope I explained it a little better.

[@simplyput2796]

So you want both circuits to be connected at the same time, or you want both circuits to be broken at the same time. That is a DPST switch, and just search your favourite online retailer for "dpst on-off" (4-pin). The 6-pin version (on-off-on) would work too, but it would be wasteful.

[@garyexgrunt7902]
