ABSTRACT:
A combination turn signal switch and dimmer switch assembly for automotive vehicles comprises a two part lever comprising an actuator and a handle. The actuator is pivoted to a switch housing for rocking movement about an axis on either side of a neutral position for selective turn signal switch actuation. The handle is pivoted to the actuator about an axis transverse to the actuator pivot axis and is movable between a neutral position and a dimmer switch actuation position. The handle has a V-shaped ramp surface engaged by a leaf spring which serves to press the handle toward its neutral position as well as to cam the actuator toward its neutral position. The turn signal switches are keyboard switches mounted on a printed circuit board secured to the housing. The switches are spaced below the path of the actuator and are actuated by forces perpendicular to the actuator path. Spring elements or flexible levers secured to the circuit board and contacting the switches extend into the actuator path. Deflection of a flexible lever by actuator movement transfers actuating force to the corresponding switch.
