Electric switch

An electric switch comprising:

• a housing;
• a manual actuating element, wherein the actuating element is movably mounted and configured to have two different actuating positions which correspond to two different switching positions;
• at least two electric contacts in the housing, each electric contact led out of the housing as electric connections, one contact being designed as a fixed contact and the other as a moving contact;
• wherein a bistable actuator for remote control is integrated in the housing of the switch;
• the actuating element interacts directly or indirectly with a control lever of the bistable actuator;
• the actuating element, the control lever of the bistable actuator, and the movable electric contact are forcibly coupled to one another;
• wherein the bistable actuator holds a permanent magnet between two yoke halves,
• wherein, through contact of the actuator with an arm of the control lever, the permanent magnet generates a closed magnetic circuit with magnetic flux generated by the permanent magnet for enabling a self-holding position of the control lever,
• wherein on both sides of the actuator there is a respective excitation winding which, when energised, generates an electromagnetic magnetic flux whose direction is opposite to the direction of the permanent magnetic flux;
• wherein the control lever comprises a driving head engaged with the actuating element, the control lever is pivotally connected to the bistable actuator, and forced to be pivoted by an interaction between the driving head and the actuating element in response to an operation of the actuating element, or energization of the excitation windings to generate an electromagnetic magnetic flux acting on the control lever.
