Hi, 
	Is it possible to use those push switches which really do act
like a toggle switch? Those found on equipment where u depress it to
switch on, press again to switch off? Or have I misinterpreted your
definition of microswitch?
Btw, it might be helpful to the rest if you give us an idea of the
currents involved..
