Definitions

  • the invention relates to a rotary switch for the Rotational movement relevant components, especially with a Actuator and a rotatable inner part, through which by converting the rotary movement into a translational movement the opening and closing of switching contacts of the rotary switch he follows.
  • Such rotary switches have been part of the delivery program for a long time of electrical companies.
  • rotary switches e.g. for multi-storey parking systems, where it must be ensured that a switching operation or removing the key with key rotary switches can only be done under certain conditions. It it must be ensured that the switch is released to switch back to the zero and thus key withdrawal position is only possible if the necessary Conditions are met, which is indicated by appropriate information, e.g. via electrical current, given to the rotary switch becomes.
  • the invention is therefore based on the object of a rotary switch to modify in such a simple way that a Switch back to the zero and key withdrawal position depending on one with an electrical circuit recorded condition can be locked.
  • An advantageous embodiment is when the locking element has an electromagnetic drive with an armature, which is connected to the bolt.
  • the bolt at least partially made of ferromagnetic material is and serves as an anchor.
  • a simple, integrated position query for the bolt is given if the blocking element has acknowledgment contacts, which opened or closed depending on the position of the anchor become.
  • a rotary switch 1 here shown in particular a key rotary switch, which is connected to a locking element 2.
  • the suitable rotary switch 1 on the front panel is the one on the front lying actuating cylinder 3 with a lock 4, a adjoining cylindrical housing part 5 and a rotatable inner part 6 shown with the actuating cylinder 3 communicates. That essentially from one Housing 7 with an electromagnet 8 and associated connecting contacts 9, a bolt 10 and acknowledgment contacts 11 existing locking element 2 is on the end of the housing part 5 snapped. The one with the armature 12 of the electromagnet 8th connected bolt 10 protrudes into the housing part 5.
  • He is as the anchor 12 is displaceable in its longitudinal axis, that its contoured end is form-fitting with the inner part 6 connects and in this way the rotary movement of the Rotary switch 1 locks.
  • the bolt 10 e.g. on the actuating cylinder 3, the Lock rotary motion.
  • the bolt 10 is through when current flows the electromagnet 8 against a retaining spring 14 moved up or against a pressure spring, in order to block the rotational movement of the inner part 6 or release.
  • the current flow is with a certain one State connected in which the provision of the Rotary switch 1 in its zero or key withdrawal position should be permitted or prevented.
  • the acknowledgment contacts 11 are here dependent on the position of the bolt 10 closed, making a simple position query of the locking element 2 is made possible.
  • the bolt 10 itself be designed as an elongated anchor, which then at least in its functional area as an armature made of ferromagnetic Material exists.
  • the previously described embodiment of the rotary switch 1 has the Advantage that the electrical area is completely protected behind the front panel or in a housing remains, what a considerable simplification to comply with certain protection types represents.
