Cheap Emergency Stop

The CE certification only certifies that it has passed it's required specification during it's design and making and not how it is used once sold.
It still has to have a seperate reset control making it not possible for the item it is stopping to start once 'pulled out' or 'twisted' to it's ON state.

Hard to explain - tomorrow I will bring my reg's book home from work and quote you what I am trying to say out of it.

RGB, yep Thanks I posted the wrong one.

I priced something like this at Platt Electric out here in Oregon and they quoted me $115! (they had to build it out of 3 different parts, but still!)

Thanks for the link. $25 is very feasible.

this has the button and key all in one.. kind of a cool feature!

Ok following some suggestions, I've now added a key switch. Can't say its great quality, but it does the job - £2.49 from Maplin.

Either it be used with a purpose made safety relay or with a standard relay and latch circuit.

Would I be complying with UK regs if both my lasers and PM25 desk got power via one of these E-stops as the desk needs a pin code on power up before the desk and lasers can be used again preventing the system restarting once the E-stop is released.

You really need a small contactor in there to as the switches are usually only rated at quite low currents.

Here is mine:

EDIT - Forgot the fuses on the diag...... DOH!

Revised drawing:-

Sorry :)

Not exactly as per my build but it will work a treat. I used one contactor contact and one fuse holder for two of the plug sockets and the other two are seperated.
