Switching device comprising a contact block having a fixed part connected to at least one electric terminal and having at least one electric contact zone able to be in contact with a contact zone of a movable part, an actuating device enabling the movable part to be moved from a closed position to an open position of said contact zones. The fixed part comprises two bases. The actuating device is formed by at least one electric coil placed between the bases. The movable part comprises a magnet able to move between two stable positions. The magnet comprises an electric contact zone electrically connected to a first electric terminal and able to be electrically in contact with contact zones connected to a second electric terminal.

Electric switching device, relay, socket and electric apparatuses comprising such a device

The electrical switching device comprises at least a first part comprising at least a first magnetizable element and a first contact zone associated with said first magnetizable element, and at least a second movable part comprising at least a second magnetic element and a second contact zone associated with said second magnetic element. The first or second magnetic element comprises at least one permanent magnetization part to keep the first electrical contact closed and to exert a contact pressure between the first and second contact zones when the movable part is in a first stable position. The electromagnetic relay and/or electrical apparatus comprise electrical contact inputs and control inputs connected to a switching device comprising electromagnetic control coils.

Electrical switching device, relay and electrical apparatus comprising same

A ball actuator comprises a case supporting a striker with an energy storage spring , a control rod movable in translation in a direction parallel to a geometric axis , detent balls and control balls . When the rod is moved in translation by an electromagnetic relay , the control balls escape and enable the detent balls to be freed so that the striker is released. Each control ball is in contact with two detent balls and with the rod so that the forces applied to the rod by the control balls are much lower than the forces exerted by the striker on the detent balls . A high-efficiency actuator is thus achieved requiring a low operating energy and with small overall dimensions.
