Abstract

A microwave oven having an electrical switch construction provided with an electrical switch that in one operating condition thereof operates the power unit of the oven and that in another operating condition thereof turns off the power unit. A timer is operatively associated with the switch for causing the switch to be repetitively in one of the conditions thereof a certain percentage of a certain increment of time and for being in another condition thereof for the remainder of the certain increment of time, the timer being adapted for selecting the amount of the certain percentage of the certain increment of time within certain limits whereby a slow to fast defrost cycle of the oven can be provided. The timer includes a rotatable cam member having a cam part for caming the switch to one of the operating conditions thereof during each revolution of the cam member, the cam part of the cam member being radially moveable relative thereto. The timer is adapted for selecting a radial position of the cam part for caming the switch or a radial position of the cam part that will not cam the switch.
