In a device (11a; 11b) for switching an electrical circuit having a contact element (15a; 15b) which closes or opens the circuit between a first and a second terminal (13a, 14a; 13b, 14b) and which has one end connected to the first terminal in a conducting fashion (13a; 13b) and, via the second free end of which, the circuit can be closed in a first end position of the contact element (15a; 15b) and opened in a second end position, and having a switchable magnetic field, preferably one whose polarity can be changed to move, by means of an actuator device, the contact element (15a; 15b) into one of its two end positions, the activating device comprises a toggle lever (23a; 23b) to move the free end of the contact element (15a; 15b) into at least one of its two end positions. In this fashion, the holding power or the seating pressure of the free end of the contact element can be increased in its closed end position.
