ABSTRACT:
A cyclable electrical switch construction, a system utilizing the switch construction and methods of making the same are provided, the cyclable electrical switch construction comprising a housing having a cyclable electrical switch therein and a rotatable actuator shaft that extends from the housing for setting the duty cycle of the switch in relation to the rotational position of the shaft in either rotational direction thereof from an "off" position thereof, and an electrical switch unit being carried on the housing and having structure operatively interconnected with the shaft so that the switch unit is actuated from one condition thereof to another condition thereof only when the shaft is rotated from the "off" position thereof in one rotational direction thereof. The cyclable electrical switch is used in a plural load circuit, preferably, as a control of a dual wattage heating element of a cooking unit.
