  • Patent number: 9653232
    Abstract: A rotary electrical switch comprises a housing having a first rotary contact space for accommodating a rotary contact and a plurality of stationary contact spaces for selectively accommodating at least one stationary contact. The housing comprises one or more closing elements for closing one or more of the stationary contact spaces not in use for accommodating a stationary contact. Another aspect comprises a locking spring member having a first portion being a resilient spring member configured for releasably engaging a locking member, while a second portion is configured for mechanically coupling to a spindle portion for imparting a rotational force on at least one rotary contact of the switch.

  • Publication number: 20110259718
    Abstract: A rotary electrical switch comprises at least one rotary contact and a stationary contact. The switch may comprise a housing with a first space for accommodating the rotary contact, a second space for accommodating the stationary contact, and a third space for accommodating the stationary contact. The second space and/or the third space is substantially closed or closable when the stationary contact is arranged in the third space or the second space, respectively. First and second stationary contacts may be arranged offset in the axial direction and/or the angular direction with respect to the axis of rotation, with first and second rotary contacts being arranged for concurrently contacting the first and second stationary contacts, respectively, in a first rotary orientation about the common axis of rotation. An improved locking spring is also provided.
