Bodge job

It is a 240v outlet. And there is an RCD on that supply as well. There are no bare wires exposed behind if someone did decide to poke there fingers around, although the only time the lathe is turned on at the wall, I'm stood at it. My kids know that dad's shed is not for playing in.

You seem to think that is safe but personally I would never leave it like that.

Exposed terminal screws, a falling object (perhaps you or one of your kids) pulling wires out, your kids or their friends meddling are all risks that could be avoided.

I presume you know RCDs do not last for ever and need regular testing. We have had one fail recently and would not trip.

Don't intend to leave it loose. As said earlier the hole will be enlarged for it to be secured in place

Mick Depending how things are wired and what you have on your machine, if you have a stop /emergency stop it might not work with your switch. The start button latches a circuit then the stop breaks it. Might be worth checking out any safety devices that are on the machine as they could well be on the same circuit and causing your original problem. If you go with your switch check out what works and what doesn't before you have to rely on it.

The stop was part of the same sealed switch unit. The latching circuit had failed so I had to hold the on button. Now the only switch on the machine is what I've fitted so it's like a light switch. Not exactly an emergency stop but it's in the same place just instead of two buttons it's a single switch if that makes sense

Makes sense. The safety devices/switches I was thinking of might have been activated if a guard was removed. A lot of machines have these and are in series with the stop start circuit. If you have these it would have been a simple job to link them out to see if one had failed.

Good luck.

I'm a definite fan of bodges but think I should point out that the original switch was probably a no volts return switch which means that if the current to the machine was cut off (power cut, someone kicking the plug etc) that you need to operate the switch again to start the lathe when the power is restored. With a normal light switch when the power comes back on the lathe would start turning whether you were there or not. Not saying don't do it, just think if that is something you are happy with.

 

(you can buy them for about 10-15 squid from axminster/ rs components etc)

A latch will drop out with a power cut as logrod says but also any safety devices fitted should do the same when a safety issue requires it. Again think very carefully about this as all will be bypassed.
