Makes sense. UV cure adhesive is tricky to cure where no light can reach it. If the sleeves were also transparent plastic you could probably make it work.

I think it would be somewhat simpler, and less power consuming, if the nail gets caught by a ramp (nose shaped hooking ramp). And the magnet pulls the "hooking-ramp" back so the nail can snap back into off-position. If the ramp is not too steep on the lockingside, you can still disable the switch manually. That way you do not need to have the magnets activated all the time, to keep the switch in position! I assume the original switches work in a similar fashion, instead of having an active magent consuming power all time while in on-position?!

I have a suggestion. Suppose you use permanent magnets to hold the switches in the on position, but *counteract* them with electromagnetic windings when you want them to disengage. This would greatly reduce the current draw of the setup as well as eliminate the need for cooling. Instead of applying constant current to keep the switches engaged, you'd only need a short pulse to disengage them.

If that's the case, you don't need permanent magnets, just some self-lock switch + a disengage elecmag. IRL jets use holding mechanism to make sure it'll always jump back to OFF as soon as the power was lost, but I have seen some low-end sim hardware for 737 use switches as what your suggestion is, my guess that type of switch is cheap anyway.

For this use, permanent magnets are not a bad idea. But for anyone thinking about using this for other purposes, you need to consider the failure mode. This has a "fail-safe" mode, in that when power is lost, it returns to its off position. Using permanent magnets would create a "fail-secure" mode, which means the switches would remain on even in the event of a power failure, which may cause issues if something needs to be off when the power is first turned restored.

Might be easier to take apart a cheap china linear solenoid. Many of them are push pulls so if you swap out the mosfet for a motor controller chip, you could flick the switch on and off. Though not sure how much force you need to pull a switch though, 15 newtons dosn't seem enough and the cheap ones don't have a pull more than 10mm

OH, shit, I completely forgot about that part. This is actually a massive thing for this video yeah. For TWP: any transistor connected to an inductive load, like a motor, electromagnet, straight up inductor etc, will HAVE to have a diode connected to the source and drain pins, because inductors will store current during charge, then release all of that when the charge stops (electromagnet turns off, in this case), and that current will likely be going straight back to the mosfet as there's nothing else connected after the electromagnet, and the electromagnet IS the inductor, so it wont be sending the current to itself. And to the mosfet this will be a reverse current, which is what a diode would help redirect to protect the mosfet. So the arduino isn't in any danger from this necessarily, but 1 diode per mosfet can still save TWP a lot of work down the line if a mosfet dies because of this. The arduino does connect to the gate of the mosfet as well though, and one thing is important to note here. If the mosfet dies, the drain's leakage current to gate can increase a lot, so assuming the arduino has pins connected directly to gate, this EMF could end up reaching the arduino. I've even had mosfets straight up just short both drain and gate to source (ground) when they die, which in this case could mean the arduino pin drawing way too much current and the circuitry connected to that pin dying. If the arduino is powered by a PC's USB, the PC's OS might actually detect the large current draw and shut off the USB though, but it can take a bit of time, and I wouldn't want to count on that. Honestly though I would just use BJTs and a diode, that way anything that breaks will be extremely cheap. but i understand that TWP chose what he did. Still really, really do need a diode though. Won't be hard to implement, just put it across drain and source, line facing the positive side, and you should be safe. Gate already seems to have resistors judging from the appearance of that board, so that one is okay at least. Diodes for gate can be a hassle sometimes because of voltage drop, and adding another resistor there would just make a voltage dividor which ends up being the same thing.

And if there was more metal at the bottom of the nail (ie a ferrous washer attached) it would need much less current to hold it since the cockpit design is not that it can be switched ON automatically. It just has to hold the switch in on position once it reaches it. In fact a permanent magnet and a small “off kick” solenoid would also work. It would only need power when tripping the switch off.

I love the amount of work you have done on this project. Making all this public and open is awesome . I made a similar switch setup but I use a permanent magnet on the end of the nail. This magnet sticks to the electromagnet by default to hold the ON position. Simply pulsing the electromagnet in the same N/S polarity as the permanent magnet will push the magnet away. This means only a brief pulse is needed on the electromagnet.

Regarding the electro magnets getting too hot, you can pwm modulate the powerdraw so it pulses on and off quickly with a mosfet and tune it so it will still hold the switch but use less power overall and thus not get as hot. Edit: I see below someone has suggested a dedicated solenoid IC and it would be an even better option. Another way to reduce power draw is to increase the surface of the part to hold, seeing as its a small rod it has a very small surface compared to the magnet, if you could have a flat wider surface you would need less power to hold it

As you're using an Arduino to do the switchng I'd definately consider PWM-ing the solonoids. So for example pulse ON for 1 second to actuate then switch to percentage PWM to hold (you'll need to do a bit of trial & error so it feels right). As a benefit you can probably do away with the fan. NOTE don't even try PWMing without flywheel diodes though!!

Man, this takes me back! In the early 90s the company I worked for did a startup simulator for the Harrier so they could practice procedures for hot and hung starts, etc. We got a cockpit built and installed instruments and displays. The two impossible tasks were barrel gauges and these switches. Both extremely expensive and impossible to find used. This was long before Internet and Ebay. We eventually subcontracted to have the gauges built for us. I don't know where we eventually found a start switch. Our engineering manager spent his weekends going round aircraft scrap yards, and aviation museums looking to buy one somewhere.

Great Stuff. Always love the ideas you come up with. One idea for "bulkier stuff" that might cause heat-problems: If you need to hold stronger stuff you might be able to use a latch-mechanism with springs. Basically a car-door lock style lock that snaps in place when you flick it on but the clasp is controlled by a solenoid and can be retracted. This will prevent you from constantly powering the magnets. ANd if the clasp is a V-Shape you can still "unlock" it by just flicking the switch. Might mess with the feedback / feeling of the switch though.

Blown away by your ingenuity! One way I have used in days gone by with current hungry solenoids is to provide the initial "attract" pulse from a capacitor. What you do is put a resistor from the supply in series with the coil to set the required holding current (typically one third of the attract current). From the junction of coil and resistor, you connect an electrolytic capacitor to ground. (Probably a few hundred microfarads would be required.) The mosfet switches the coil to ground, When the mosfet is off, the capacitor charges up to supply voltage via the series resistor. When the mosfet turns on, an initial high pulse of current flows from the capacitor, dropping after a few milliseconds to the holding current supplied via the resistor. When the mosfet goes off again, the capacitor charges up via the resistor again, probably taking just a few milliseconds.

I got an idea for you!!, though you are extremely creative with your own. But perhaps this will work great for a DC Bus/distribution system: If you use a relatively low current DC breaker toggle switch (you can get small 1amp DC breakers that look and act like toggles) - you can trigger a trip from ON to OFF using a simple crowbar circuit driven by either a MOSFET or relay. The crowbar circuit will cause a momentary short/load through an appropriate resistor when triggered, ultimately disengaging the load connected and tripping the toggle. This will work excellent and reliable for ON to OFF situations but not vice versa.

You could likely use a weaker electromagnet by increasing the surface area it is in contact with on the lever. At the moment you just have the relatively thin nail, if you glued a washer or metal disc to it then you would greatly increase the surface area and increase the pulling strength, meaning you need a weaker magnet which would use less power too.

I think if you already have an arduino board and if it is NOT so IMPORTANT to have a visual aspect of the key activated and held by the magnet, in that case I would use that same momentary contact key and leave it up to the arduino to undo this "contact" which is made by the magnet. if you want visual information, you could use green led for "on" and red led for "off" my sincere congratulations, your cockpit is AMAZiNG!!! ;)

This will give you a common 12V provider with decent amperage, and if it fails you have a common part to exchange for that would be plug and play without having to do any modifications, and you can still get it RMAed :D

Awesome swtiched! May I make a suggestion; add protection diodes (flyback protection) on each electromagnet. Don't really see any on the mosfet driver board. The electromagnets are zapping themosf ets everytime they are turned off which will cause the mosfets to fail over time. Protection diodes are reversed diodes in parallel with the electromagnets, this will allow the current generated when the magnetic field collapses in the coils to go thru the diode and not thru the mosfets. Very important.

You can use a better solenoid driving circuit, adjust the holding current, and add absorption elements for the inductive kickback

This is awesome. A linear push pull solenoid paired with a switch with no spring would probably fix your heating issues since it will only need powered momentarily.

With the addition of a small inverter circuit to create AC current and the use of relays to switch the AC to the electromagnets you could greatly reduce the heat generated by the electromagnets using the resonate frequency of the electromagnets....ie. the right frequency.

Great! It works so well. I would suggest you use 5 minute epoxy instead of that UV glue. It really isn't that strong. But if it works I guess I am wrong.

UV glues, like Bondic, are very strong. They have a lot of advantages, especially when you want to take time to position the items before curing. But you need to make sure the the light can reach all of the glue. Otherwise there can be uncured glue that is a weak point. I doubt these will fail any quicker than your epoxy suggestion.

@@MeppyMan I suggest that he just uses both methods to bond something reasonable together and to see what his results are. I was concerned that he was flowing the glue down into the holes and around the brass piece... that the light would not get into there as deep as he might need for the long term. I have Bondic and tried to use it on Circuit Boards to hold bodge wires and other things in place for my Halloween and other projects... Because I wanted to stop using Hot Glue. My results were horrible in the long term. 5 Minute epoxy doesn't require Light to bond them and I have never had that fail before. Your mileage might vary.

In the early 2000,we didn’t have have any DC solar light switches , the fines for not having your mast light on at night was around $85 ,(I’m a liveaboard) LEDs were out and expensive ,with no solar switches, I got my magnetic switches from the junk yard, in side the hood,over the wheel well,you have a black plastic box,inside,you have 4 to 5 magnetic switches,(12volt) I would hook my cheap Harbor freight solar panel to the leads that control the magnetic switch and the other leads to the LED mast light via the 12 volt battery , when the sun went down ,the energy dropped and the magnet would release,closing a circuit and turning on my LED mast light , today we have DC solar activated LED lights ,

splendid excellent work! Just one remark: make sure that the metal mounting base of the MOSFETs do *not* touch each other. Depending on the circuit design that may cause issues. The 2 MOSFETs in the middle are awfully close to each other ... Just love this idea!

The problem with the heat is because you need to reduce the current when in holding. I made a whole bunch of auto throw switch mods to one sim I made and used a resistor in a heat sink plus a timer that went from attract to hold… in attract it was high current but then switched to low current for the hold. As the Hog only uses a hold you shouldn’t be getting excessive heating in the coil… that’s a sign the current is way too high (and yeah, my first experiments had the EM get so hot you could burn yourself). I’m trying to remember which sim I built them for now. I’ll have to dig through my notebooks. That said… such a nice and simple design (mine was a right frankenswitch)… but to reduce the current just a simple low value resister will stop your runaway current problem.
