Abstract
An electromechanical switch includes a main contact provided with a number of main fixed contacts and a mobile main contact bridge; an auxiliary contact which precedes the main contact in the switch-on process and includes a number of auxiliary fixed contacts and a mobile auxiliary contact bridge; and a contact bridge carrier for actuating the main contact bridge and the auxiliary contact bridge. At least one of the contact parts is spring-mounted. The electromechanical switch has two stable positions of the auxiliary contact bridge or the auxiliary fixed contact. During the switching on process carried out by actuation of the contact bridge carrier via the auxiliary contact bridge or an auxiliary fixed contact in the first stable position, the auxiliary contact closes before the main contact, and during the switching off process by actuation of the contact bridge carrier in the opposite direction, the auxiliary contact with the auxiliary contact bridge or the auxiliary fixed contact in the second stable position opens before the main contact.
