SAFETY RELAY WITH GUIDED CONTACT SET AND MONOSTABLE DRIVE

摘要

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