ABSTRACT:
A mechanical-type automatic circuit-breaking appliance switch assembly includes a switch housing, a switch unit, an elongate switch actuator and a biasing member. The switch housing is formed with a slide channel and is formed with an opening that is aligned with the slide channel. The switch unit is disposed in the switch housing adjacent to the slide channel. The switch unit has contact terminals that extend out of the switch housing, and a switch contact that faces the slide channel and that is capable of being pressed to operate the switch unit from a circuit-breaking state to a circuit-making state. The switch actuator is received in the slide channel and has first and second portions. The switch actuator is movable in the slide channel between a first position, where the second portion extends out of the switch housing via the opening and the switch actuator does not press the switch contact to operate the switch unit in the circuit-breaking state, and a second position, where the second portion extends into the switch housing via the opening and the switch actuator presses the switch contact to operate the switch unit in the circuit-making state. The biasing member is disposed in the switch housing and biases the switch actuator to the first position.
