Abstract

A power control includes a thick film resistor on an electrically insulating support plate, for heating a bimetal strip operating switch contacts connecting power to a load, and to the resistor. The support plate is secured and the resistor thereon is electrically contacted by means of a resilient clip at one end, in the vicinity of a fixed end of the bimetal strip. An opposite end of the support is connected to a power source via a movable contact spring. An opposite free end of the bimetal strip acts directly on the switch contacts to disconnect power upon bending of the bimetal strip with heat. The bimetal strip and a control operator for biasing the bimetal strip are shaped like an L, with two legs pivotable around a pin adjacent the base of the bimetal strip.
