ABSTRACT:
An adjustable cycling switch has one condition for direct application of power to the primary winding of a transformer coupled at its secondary to energize a magnetron that provides microwaves in a microwave oven or the like. The cycling switch also has a second condition for variable adjustment to provide for periodic cyclical energization of the mentioned transformer and magnetron to reduce the effective average microwave power. During such cyclical energization of the transformer and magnetron, power is briefly supplied to the transformer through a surge protection or current limiting resistor at the beginning of each such cycle to reduce the high currents that may otherwise occur in the circuit which could damage switch contacts, the magnetron, and other circuit components; and afterwards full power is supplied and is later cut off.
