Abstract: An electric switch having a circuit breaker includes a manually operable actuator that moves one contact between a first and a second position. A bimetal member moves another contact between a first and a second position in response to an electric current above a given threshold passing therethrough, and the movement of this contact to the second position releases a catch that retains a spring loaded indicator in its retracted position. The two contacts abut one another closing the circuit when both contacts are in their first positions. An excessive current will therefore break the circuit and release the indicator to move to the extended position. The releasable catch resets after the bimetal member has cooled and it will again retain the indicator in the retracted position when it is subsequently manually depressed.
