摘要:
An electrical overload protection device for readily identifying and resetting a tripped circuit breaker includes a button, which is retained in depressed and extended configurations by a biaser. A first end and a second end of a plate spring are attached to the housing and the biaser, respectively. A bimetal strip, which is attached to and positioned in the housing, is reversibly deformable and thus bendable upon exposure to a specified current. Depressing the button contacts the biaser with the bimetal strip to complete an electrical circuit, which, should it exceed the specified current, bends the bimetal strip to actuate the plate spring to extend a shaft from the housing. The bending also disengages the biaser from the bimetal strip and breaks the electrical circuit. Depressing the shaft reverses deformation of the bimetal strip and reextends the button so it is again depressible to complete the electrical circuit.
