  • Electrical switch element, particularly a relay, with swivelling lever switch mechanism
    Patent number: 7939992
    Abstract: An electrical switch element, particularly a relay, is provided with an actuator with a switch contact and a switch mechanism. The switch mechanism translates a driving movement of the actuator into a switching movement of the switch contact so that the switch contact is brought into and out of contact with a mating contact. In order to create a switching movement with a large lift in the case of an actuator which can only execute a driving movement with small lift, the switch mechanism has two swivelling levers connected to each other via the actuator and at least one contact retainer. The contact retainer connects the two swivelling levers in its longitudinal direction with a lever arm larger than the actuator and is configured so it can be deflected transverse to its longitudinal direction.
