Rotary stepping switch with contacts on disc and support plate - has several contacts on concentric paths and radial contact bridges for two circular paths

摘要

The switch has a plate (3) on which is rotatably mounted a disc at a given spacing. Underneath the disc are mounted on the plate contacts on concentric circular paths. The disc has several retaining positions each for a contact bridge of identical shape. The bridging span is identical and designed to bridge in each case two contacts (10). Several concentric contact paths are provided. The contact bridges are insertable through the central radial opening in different angular positions in such manner that each can bridge two circular paths of any arbitrary distance. Preferably on the plate side away from the disc is mounted a similar second disc, rotatable together with the first one.
