DE2329121B2 - Drive arrangement for rotary switches - Google Patents

Description

In a known arrangement of the above Art (Siemens price list NV March 2, 1973. pp. 10 to 18) there is a catch for the handle in the door e.nes control cabinet, so that the position of the handle When the door is opened, this shave is retained the handle had to hold in every position, are the losses occurring here, ie. Forces to Turning the handle against this detent is relatively large, which means that, for example, the toggle a motor protection switch not also as a switch position indicator can be used; because the locking forces can be so large that the gag cannot be brought into the exhibition without additional information

The invention is therefore based on the object. a drive arrangement of the type mentioned above sharp where it is possible. d.E handle with open To hold the door in the position it has just assumed, but with the door closed the inhibiting action to keep a detent so kle.n that the toggle of a motor protection switch as Schaltstellunganze.ge can also be used.

The free end 13 of the spring 14 stands out from the rotary cylinder 12, so that the inhibiting effect between flange 6, d. H. Rotary cylinder 12 and leaf spring 14 is canceled. The handle can be rotated freely and only needs to apply the forces specified by the switch shaft 10. One on that Flange 6 pivotably held bolt 18 is used to lock the switch position-dependent. Door. That Coupling part can be designed so that the door can be opened in certain positions, i. h., a The recess in the coupling part releases the bolt and thus enables the door to be opened.
