If your high power contactor has an auxiliary contact, it is possible 
to do this without another relay. Just wire the aux contact to hold 
the coil energized after the start switch is depressed, and use a 
normally closed stop switch to momentarily interrupt the control 
power to the contactor coil. Perhaps this will help keep expenses 
down. Of course with this setup the handheld control will be carrying 
line voltage as opposed to 24 volt or whatever.
