ABSTRACT:
A motor starting switch particularly intended for use with a two speed electric motor actuable by a centrifugal actuator upon start up of the motor so as to energize the high speed and auxiliary windings of the motor for start up of the motor and for deenergizing the auxiliary winding and energizing the selected high or low speed winding of the motor after the motor has accelerated to a predetermined operating speed. The switch has a resilient, current carrying, force transmitting member interconnecting the plunger of the switch operated by the centrifugal actuator and a switch arm for energization of the auxiliary winding and for effecting movement of the switch arm within the switch.
