Abstract

A safety relay has a guided contact set (16) and a monostable drive with a H-armature (6). The individual contacts of the set of contacts (16) are located in separate chambers and are actuated by a common actuator (20). In order to miniaturise the relay while having a low power consumption, a mechanically symmetrical H armature (6) with an asymmetrical magnetic effect is provided to ensure the monostable drive. The longitudinal axis of the H-armature (6) is approximately parallel to the longitudinal axis of the driving coil and the axis of rotation of the H-armature is perpendicular to the longitudinal axis of the driving coil. The actuator (20) is actuated by an actuating plate (49) which prolongs the H armature.

Claims
