Rotary switch

In a rotatable switch adapted to be installed in a switch panel opening, the switch including a rotatable knob, an elongated housing, a rotatable annular detent body within the housing and connected to the knob in axially spaced relationship, the detent body cooperating with at least one detent element attached to the housing for frictionally holding the knob and the detent body at a set angular position and limiting its total angular motion, an annular rotatable cam member cooperating to open and close spring switch circuit elements, said spring switch circuit elements supported by a switch retainer within said housing and being axially spaced from said rotatable cam member, the improvement comprising:

• said cam member being connected to said rotatable detent body in coaxially spaced relationship for rotation therewith, said cam member having switch controlling cams on at least a portion of its surface area and being connected to said detent body through a releasable variable position connection, said spring switch circuit elements including cam follower portions engageable with said cams for controlling the opening and closing of the switch elements when the cam member is rotated, whereby adjustment of the angular relationship between said cam member and said detent body can be carried out.
