Configuring an Emergency Stop Switch for your DIY project

I recently added an emergency stop switch to my lathe. The install was not that hard but there were several unexpected challenges specifically with the switch. This video covers those challenges and should help you with your switch install.

Very helpful for my robotics application, thanks a lot! I had figured out what NO/NC are, but I came into this with the background of a relay, so I was expecting a common line to go to NO and NC

[@dazecars]

Glad it helped!

[@CopeCory]

Another great info video. Thanks so much,

[@dazecars]

My pleasure

[@WireWeHere]

5:42 In regards to modular pushbuttons you can even find different timing of contacts to set a shut down sequence for example

[@dazecars]

That is good info to know, thanks for sharing

[@Glens1965]

A couple of nuggets of information there.

[@dazecars]

Only a couple?? 😂😂😂

Glad it was helpful!

[@AyannaGeorge]

Thank you helped me understand alot of my problems.

[@dazecars]

Glad I could help

[@mikeulloa]

Very helpful 😊

[@dazecars]

Glad you think so!

I hope you see this. I am setting up a NO/NC stop for a 12v motor I have a jumper between the NC (in) and NO (in) then fuel pump trigger and coil on NC (in) then fuel pump and coil on NC (out) then ground for NO (out) It tested fine once but now the NO is closed all the time so it’s all grounded constantly and the motor won’t run

[@dazecars]

based on how you have it wired that makes sense. When the NO is closed it would connect to ground because one side is grounded.

[@saeedbawazir2505]

Very informative

[@dazecars]

Glad it was helpful!

[@rayg436]

that N/O switch could be used for a brake on the motor or the lathe itself. like your capacitors that you were using a while back.

[@dazecars]

The resisters as a break are automatic as soon as the power is cut but yes it could be used to engage some other brake.

[@FOHGeek]

Yeah. If the lathe is powered by a DC motor, then the easiest way is to wire the N/O contact in parallel with the motor. When the E-stop is slammed, the N/C point will cut the power and the N/O point will short out the armature and thus create lots of electromagnetic drag to stop the motor quickly.

[@dazecars]

IMHO not a good idea. I have an entire video series on a braking system for a DC motor linked blow. Also this switch needs to be on the AC side as it's lower amps and can't even come close to handling the DC amps. kzbin.info/aero/PLg4j6XzBdSY-oFUIBZCx5O6i6JjihSqHL

I found out that you can order them with two NC switched so there’s no need to purchase extra ones. Good video DC. Now all I need to do is figure out how to subscribe 1000 times to your channel. I’m having a bitch of a time trying to find a push button on off switch that can handle 120 vac and 15 amps. Some on Amazon say 120 V, 15 amp, but I don’t know how to wire it for ac. No, I’m not asking for help. Why is it so easy to find a rocker switch for this, but not a push button? Seems like they are mostly for dc. P

[@dazecars]

What push button switch are you looking at?

[@j1mbobtech]

some can accept stacked switches also...

[@dazecars]

thanks for the tip

[@ChoicesAndTradeOffs-tt3rp]

Thanks for great explanation! You have a new subscriber

[@dazecars]

Thanks for the sub!

[@h2hpunisher236]

I opened that screw 😢

[@dazecars]

You can get it back together just make sure you clock it correctly or the spring action won't work properly

[@Nick_L]

Just wanted to say thank you so much for all these videos. It helped me a lot on my treadmill motor lathe conversion. kzbin.infoQhdQdPNqTBE

Ohh, stop it 😬
