If the Start-Stop switch you're referring to uses the Start button to
mechanically close the contacts (and current latches the contacts closed),
then the Stop button opens the coil's holding-current circuit to allow the
contacts to open.. I've seen these types of switches on workshop machines
from China.
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.

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.

Hi,
I just became aware of this item:

http://img-europe.electrocomponents.com/images/R3985229-01.jpg

Data sheet he

http://www.pdfdoc.ru/data/pdf42805

It includes a 2-pole 16A contactor in that little size. Can also be
ordered
with the option of external connection for safety stop push-button switch.

I can't find a USA distributor for these. Anybody know where to get these?

The company is in Germany:

Or is there a domestic (USA) product that is similar?

Thanks,
Dave
