Definitions

  • the invention relates to a switching device with an NC switching element, whose movable contacts by one Slider can be actuated.
  • a generic switchgear has long been included in the scope of delivery from various switchgear manufacturers. It includes in essentially an actuator, a fastening part for fastening on a front panel and a positive opening NC switching element.
  • the normally closed switching element can be via a Actuate slide that can be coupled to the actuator. Will this Coupling, usually a snap or screw connection, between actuator and slide not or not properly the switching device loses, e.g. a EMERGENCY STOP command device, its functionality and thus its Protective function without being noticed because the EMERGENCY STOP circuit remains closed despite actuation.
  • the invention has for its object a switching device create the above type, which is a safe shutdown of a consumer circuit.
  • the task is accomplished by using the break contact in Series normally open switching element solved, the movable Contacts are actuated via the slide, the NO travel of the NO switching element and the NC travel of the NC switching element are matched to one another in such a way that to turn on the switching device by pressing the Slider a switching state can be reached in which the Normally open and normally closed switching elements closed at the same time are and that from this switching state by actuation of the slide the NC switching element in the OFF state is transferable.
  • the invention is advantageously used in EMERGENCY STOP command devices utilized.
  • the figure shows an EMERGENCY STOP command device 1, which is an actuator 2, a fastening element 3, and an NC switching element 4 and a normally open switching element connected to it 5, which can be operated via a slide 6 are.
  • the contact bridges 7 are spring-loaded in windows of the slide 6, not shown here arranged and in the longitudinal axis of the slide 6 movably mounted.
  • the switching elements 4 and 5 are housed with the slide 6 in a housing 10 as an assembly, the one intended for coupling to the actuator 2 End of the slide protrudes from the housing 10.
  • the Drawing shows the switching state in which the normally closed switching element 4 closed and the normally open switching element in the open Condition is, with the movable contacts 9 around the Normally open travel s from the fixed contacts of the normally open switching element 5 are spaced.
  • the slide 6 can be operated translationally by at least the closer path s into one Move switching state in which both the normally closed switching element 4 and the normally open switching element 5 in the closed Condition. This is the ON state of the EMERGENCY STOP command device 1 in which the consumer circuit is closed is. Only when the actuator is operated again 2 is by a further displacement of the slide 6 by one NC path, the NC switching element 4 opened and thus the circuit is interrupted.
