Abstract
The rotary light switch for motor vehicles has a housing (10) and an actuating member (14) mounted rotatably. In a peripheral wall (24) of the housing, a cam surface (26) is recessed, which runs in peripheral direction and rises axially facing axially away from the actuating member. A cam follower (22) projects radially from the actuating member (14) and runs up on the cam surface on rotation of the actuating member, bearing only axially on the cam surface and forcing the actuating member (14) to move axially.
Claims8
A rotary light switch with a housing and with an actuating member mounted rotatably about an axis in the housing, a peripheral wall of the housing being formed with a cam surface which runs in a peripheral direction and rises axially facing away axially from the actuating member, the actuating member having a radially projecting cam follower that runs up and bears axially on the cam surface on rotation of the actuating member forcing the actuating member to move axially.
The rotary light switch according to any of the preceding claims, wherein the cam surface rises linearly axially.
