Default How do I know if I need a new switch for 240v?

The Switch (A regular switch that is) is ok if you flip it one way and
the motor starts and if you flip it the other way the motor stops.


False. The switch is ok if that occurs, *and* the switch is rated for

both
the
voltage and the amperage that it's switching. Better still if the switch
disconnects all of the hot conductors going to the motor.


Well, that's false also. A switch for a motor has to be rated for the hp

of
the motor. You can be okay on voltage and amperage and still fry the
switch. It happened on my used table saw; the switch fused closed.



Please Toller - go study ohm's law.
