How about a real limit switch? http://www.ebay.com/itm/380653721209

He needs a DPST, not an SPDT. I'm with Don on the AC relay as a
simple fix, with a simple wall switch actuator.


The photo in the listing shows four terminals in two sets of two, so
it looks like the description is wrong.


The photo of the label shows that it has either one pair of
terminals connected or a second one. Sort of single pole single throw,
if you connect say screws 2 and 3 together.

Not what is needed in this case -- assuming a 240 VAC motor.


I would use a small two pole contactor to shut off the motor. It
would be able to handle a lot more current, and reduce the wear on the
actual limit switch.
