Abstract
A motor starting switch including a pair of auxiliary switches operable in response to the stopping of the drive motor of an electrical appliance or the like for disconnecting both sides of an electrical load in the appliance (e.g., for disconnecting a heating element) from the input power lines thereby to reduce shock and fire hazards of the appliance due to a short circuit of the load when the appliance is turned off, and for automatically connecting the load to the input lines of the appliance in response to start up of the motor.
