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 coupling device comprises a transformer having a primary winding in series with a two-way switch controlled via an optocoupler and a three-position selector switch by a control circuit. In standby mode, the switch is connected to an oscillator defining a switching frequency (49 kHz) ensuring power supply of the control circuit, which circuit is able to detect the presence of a carrier on the transformer secondary winding. In receipt mode, the switch is closed and the control circuit analyzes the modulated information received on the transformer secondary winding. In transmission mode, the control circuit causes switching of the switch at the information modulation frequency (132 khz), performing both power supply of the control circuit and transmission of the information.
