Circuit breaking switch with fusible element that responds to current overloads

摘要

This invention provides a switch adapted to close upon pressing by an actuator of a movable piece initially in an open switch position, the actuator being made of a material which melts at a predetermined temperature. The switch opens when melting of the actuator by the heat generated from an overcurrent allows the movable piece to return to its initial position. The movable piece is made of a material which fuses at a predetermined temperature, such that the switch opens upon fusion of the movable piece by the heat generated from the flow of an overcurrent through the movable piece.
