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.
