ABSTRACT:
The present invention relates to a device for power control to the magnetron in a microwave oven. The two timer switches conventionally used for controlling the power to the magnetron may be replaced by a configuration in which only one timer switch is used. The timer switch formerly used for switching between high power mode and low power mode is replaced by a microswitch with accompanying driving mechanism. The microswitch is controlled through action of a continuous pressing element, cam, and a band spring so that the cooking modes can be switched between high and low power mode in a manner equivalent to that of known timer switches.
