Abstract
A rotary dimmer switch assembly for use with a vehicle push-pull switch controls at least one light dimming function. The rotary switch assembly comprises a stationary cam contact assembly, and a rotating carder assembly which carries a circuit element having an exposed circuit trace surface. The cam contact assembly is fixed to a circuit board and has a plurality of contact arms having one end biased against the circuit element circuit trace surfaces and the other end electrically connected to the circuit board. The cam contact assembly guides the rotation of the carrier assembly about the longitudinal axis of the push-pull switch. The circuit element rotates with the carrier assembly, which is rotated by rotation of a push-pull switching component, and the circuit trace surfaces sweep across the contact arms thereby controlling the light dimming function. A method of assembling the rotary potentiometer assembly is also disclosed.
