Harbor Freight, or any number of other machine importers/sellers could
probably supply a switch of this type.
The parts lists are available from at least a couple of said companies.

I've searched for "No-Volt Release" (NVR) switches and have found very, very
few here in N. America. The US definition is a full contactor inside a
housing with a start/stop combo switch on the front. Not my idea of "min".

Europe uses these much more.

HF doesn't list anything like this.

If you know of any manufacturers I'd be glad to know of them.

So, if it is this type of switch, any interruption of the coil current will
cause the contacts to open, and cause the machine motor to come to a stop
(until the Start button is used to close the contacts again).. meaning that
a commonly available normally closed (momentary open) switch with the proper
voltage/current ratings wired in series with the coil circuit will also act
as a Stop switch (E-Stop or other terminology).. unless the contacts become
stuck shut.. then the OH**** switch needs to be utilized.

This isn't the standard method commonly used in the US, for
starting/stopping a machine motor, but it is a cheaper way to produce a
motor starter.

That's the plan...
