Cannot find a push-off / key-on switch...

Externet · Nov 20, 2022

Hi.
It looks like the image :

Slides in by pushing it in by thumb to open a circuit turning something off. To restore continuity on, only a key pops it out again.

Any clues where to find such animal ?

It's a filing cabinet push lock - never seen one with an integral switch.

Is the switch a seperate assembly to the lock itself?

There is no inflation, it is pure nasty greed.

Try looking for "lockable emergency stop button" on ebay. (Or elsewhere .) Here is one example.

How about a DIY type? One of the cabinent locks and a micro switch . With the lock out, the NC contacts are used and broken when the lock is pushed in and it hits the micro switch.

Where does your sense of entitlement come from? The last century perhaps.

I believe you must have been looking at an obscure version of a machine Emergency Stop type switch?

Those have safety-of-life type ratings and certifications compliant with UK/US/EU laws, they are not just electrical switches like the Aliexpress versions.

The commoner versions of ES switches are more like £30 - £50, depending on details.
