I recently purchased a work bench and all its contents. The pictures below are of a small switch type device I found in the bench. This electronic looking device seems out of place in the bench. So my question is, What is it?

The other side.

That is a "Micro Switch". If you press the red button, it connects or disconnects a circuit from the center pin to one or the other end pins.

Any idea why it would be in a watch makers bench?

It may well be from a ultrasonic cleaner they have one of these to turn off the ultrasonic if a pot is lifted out of position, I bet it is the same type, next tiem I have to bottom off for cleaning will look

Hi Ronny,

I'm no "sparkie" but isn't this a 240/250 volt AC switch? I'm just thinking it may overload your 110v US circuits. On the other hand, as I said, I'm no sparkie!
