(54) Rotary switch


(57) A rotary electric switch has a rotor (1) which can turn relative to a stationary base assembly (3), and which carries a sliding contact member (2) designed to bridge between a stationary feed contact member (6) and a stationary output contact member (4) on rotation of the rotor (1). An auxiliary butting contact member (5) is biased by a spring (7) towards butting engagement with contact members (4,6) and against a camform (9) on the rotor (1). As rotor (1) turns electrical contact between contact members (4,6) is first made through sliding contact member (2) and then additionally through auxiliary member (5).
