摘要：
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.
