Definitions
- the invention relates to a rotary switch with for Rotary motion relevant components in a first housing, in particular with an actuating element and a rotatable Inner part, about the opening and closing of switch contacts of the rotary switch takes place.
- Such rotary switches have been part of the delivery program for some time of electrical companies.
- applications e.g. in storey parking systems, where it must be ensured that a switching operation or a removal of the key with key rotary switches only under certain conditions. It must be ensured that a release of the switch To switch back to the zero and thus key withdrawal position only possible if the required Conditions are met, which is supported by appropriate information, e.g. via electrical current, given to the rotary switch becomes.
- the invention is therefore based on the object, a rotary switch in a simple way to modify such that Switch back to the zero and key withdrawal position depending on one with an electrical circuit entered condition can be locked.
- a simple, integrated position query for the bolt is given if the blocking element has acknowledgment contacts, which are opened or closed depending on the position of the armature become.
- a rotary switch 1 shown here in particular a key rotary switch, which is connected to a blocking element 2.
- suitable rotary switch 1 is the front lying actuating cylinder 3 with a lock 4, a itself to subsequent cylindrical housing part 5 and a rotatable inner part 6 shown with the actuating cylinder 3 communicates.
- This essentially consists of one Housing 7 with an electromagnet 8 and associated connection contacts 9, a bolt 10 and Acknowledge contacts 11th existing blocking element 2 is on the housing part 5 end snapped.
- the with the armature 12 of the electromagnet eighth connected bolt 10 protrudes into the housing part 5.
- He is as the armature 12 so displaceable in its longitudinal axis, that its contoured end form-fitting with the inner part 6 connects and in this way the rotational movement of the Rotary switch 1 locks.
- it is also possible through Engagement of the bolt 10, e.g. on the actuating cylinder 3, the Lock rotary motion.
- the bolt 10 is in current flow through the electromagnet 8 against a retaining spring 14 after moved down or against a pressure spring down, to lock in this way the rotational movement of the inner part 6 or release.
- the current flow is with a certain State associated with the provision of the Rotary switch 1 in its zero or key withdrawal position allowed or prevented.
- the acknowledgment contacts 11 are position-dependent here by the bolt 10 closed, creating a simple position query of the locking element 2 is made possible.
- the bolt 10 itself as an extended anchor, then the at least in its functional area as an anchor made of ferromagnetic Material exists.
- the previously described embodiment of the rotary switch 1 has the Advantage that the electrical area completely protected behind the front panel or in a housing remains what a considerable simplification for compliance with certain types of protection represents.
