ABSTRACT:
The electric power control switch of the present invention includes a plurality of contact assemblies which are repeatedly opened and closed by a motor driven timing cam and two manually operated control cams. The control cams also control the position of associated operating levers which cooperate with additional plural contact assemblies. The relationship of the motor driven timing cam, manually operated control cams and operating levers provides an unique switching arrangement whereby the period for operation of an oven, range or other electrical appliance is widely varied and switch contact life is enhanced.
