  • the operation of the safety relay 5 will be explained briefly below. Basically, the operation of a safety relay is known.
  • a magnetic field which pulls the hinged armature 50 in the direction of the contact surface 64 and thus closes the magnetic circuit, builds up in a manner known per se.
  • the movement of the hinged armature 50, the freely movable end 42 of the diagnostic contact spring 40 and thus the actuator 30 is moved toward the end plate 170.
  • the spring contact pieces 44 and 46 and the fixed contact piece 27 are separated and the opener is opened.
  • the longitudinal axis of the hinged armature and thus the longitudinal axis of the diagnostic contact spring 40 parallel or nearly parallel to the coil longitudinal axis.
  • the actuator 30 also presses the contact receiving portion 157 of the load contact spring 150 toward the end plate 170, so that the spring contact piece 160 comes into contact with the fixed contact piece 190 of the load fixed contact carrier 180. As a result, the load contact and a load circuit connected to the load contacts 145 and 184 are closed.
  • the compact design of the relay 5 results from the fact that In particular, the diagnostic contact spring 40, the coil 80, the armature 50 and the load contact spring 150 are sandwiched to each other.
