The invention relates to an electric rotary switch comprising a switching rotary unit (5) arranged in a housing provided with at least one switching contact (13) acting on switching contact paths (2) associated to socket (1). The rotary switching unit (5) is coupled with an actuating element (8) and interacts with a locking sleeve (9), bevel (10), or indentation (11) for determining switching positions. The locking sleeve (9), bevel (10), or indentation (11) are associated, in part with a face oriented towards the socket (1) of the rotary switching unit, and in part with the rotary switching unit.
