Abstract
A push-to-turn thermal cycling switch for regulating the wattage of a resistance type surface heating unit of a domestic cooking range of the electric type is disclosed. The duty cycle of the heating unit, and thus its heat output is regulated by the switch cycling on and off in accordance with movement of a switch-contained bimetallic element heated by current flowing to the heating unit via the switch. The switch cycling is determined by the position of a disc cam member carried on an axially shiftable, user-rotatable shaft having a detent means for rotatably locking the shaft at an 'off' position. The shaft is formed in a single step die-casting operation. A latch secured disc cam retainer facilitates machine assembly of the switch components.
