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.
