Abstract
An electromagnetic relay, in particular a motor vehicle relay, contains a magnet yoke, a relay coil, a hinged armature which is pivotable about an axis of rotation and on which a moving contact, as working or switchover contact, is retained relative to at least one fixed contact. A piezo actuator is provided, which keeps the working or switchover contact closed when the relay coil is de-energized as a result of the actuation of the piezo actuator.
Claims21
An electromagnetic relay, comprising:
- a magnet yoke;
- a relay coil;
- a moving contact;
- a first fixed contact;
- a hinged armature being pivotable about a rotation axis and on which said moving contact being held relative to at least said first fixed contact;
- and
- a piezo actuator which, as a result of being actuated, keeps said moving contact closed when said relay coil is de-energized.
