Switch Arcing in Player Piano
By Andy Taylor 

How about a 110-volt heavy-duty relay ?  Wire up the microswitch to
activate the relay when the microswitch is on.  That way, the only load
on the switch is the field coil of the relay.  The contacts in the
relay itself will bear the amperage of the suction motor.  Just a
thought.

Best Regards
