Abstract: A fault interrupter and load break switch includes a trip assembly configured to automatically open a transformer circuit electrically coupled to stationary contacts of the switch upon the occurrence of a fault condition. The fault condition causes a Curie metal element electrically coupled to at least one of the stationary contacts to release a magnetic latch. The release causes a trip rotor of the trip assembly to rotate a rotor assembly. This rotation causes ends of a movable contact of the rotor assembly to electrically disengage the stationary contacts, thereby opening the circuit. The switch also includes a handle for manually opening and closing the electrical circuit in fault and non-fault conditions. Actuation of the handle coupled to the rotor assembly via a spring-loaded rotor causes the movable contact ends to selectively engage or disengage the stationary contacts.

Abstract: The invention relates to a reed contact unit (1) for electric switching functions, comprising a metallic contact blank (2) featuring a base (3) with at least one contact arm (5) configured integral with it, and comprising an electrically non-conducting frame part (7) accommodating fixedly the base (3) of the contact blank (2). To avoid deformations and damage to the contact arms (5) of the reed contact units (1) when used in bulk, at least one of the long sides (12) and the front end (9) of the contact arm (5) are surrounded by at least one frame shank (8) configured integral with the frame part (7), the front end (9) of the contact arms (5) being fixable releasably in the frame shank (8).

Abstract: A switch device for controlling an electric motor which is used, for example, in a power window or sunroof of an automobile. The switch device includes a magnetically attractive piece, an electromagnet, sets of electrical switch contacts, and a spring coil of an alloy which, when heated to a predetermined temperature after being compressed, is restored to a released position.
