Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
A turn signal switch assembly comprising a support having a mounting surface, a manually operable turn signal lever pivotally mounted on the support for rocking movement in a path generally parallel to the mounting surface, right and left turn signal switches on the mounting surface for selective operation by the lever upon rocking movement thereof in either direction, an element of each switch being movable generally perpendicular to the path of the lever for switch actuation, and means for translating the lever motion to a switch actuating motion comprising yieldable leaf spring means secured to the support and lying in part between the lever and each switch, the spring means having for each switch a portion extending into the path of the lever so that movement of the lever against the portion causes deflection of the spring means against the said element in a direction to actuate the switch.
Claim 2
Dependent Claim
149 words
A turn signal switch assembly comprising a support having a mounting surface, a manually operable turn signal lever pivotally mounted on the support for rocking movement in a path generally parallel to the mounting surface, right and left turn signal switches on the mounting surface for selective operation by the lever upon rocking movement thereof in either direction, an element of each switch being movable generally perpendicular to the path of the lever for switch actuation, and means for translating the lever motion to a switch actuating motion comprising yieldable leaf spring means secured to the support and lying in part between the lever and each switch, the spring means having for each switch a portion extending into the path of the lever so that movement of the lever against the portion causes deflection of the spring means against the said element in a direction to actuate the switch.
Claim 3
Dependent Claim
172 words
A turn signal switch assembly comprising a support having a mounting surface, a manually operable turn signal lever pivotally mounted on the support for rocking movement between two limits in a path generally parallel to the mounting surface, right and left turn signal switches on the mounting surface adjacent the limits of the path of the lever for selective operation by the lever upon rocking movement thereof in either direction, an element of each switch being movable generally perpendicular to the path of the lever for switch actuation, and means for translating the lever motion to a switch actuating motion comprising yieldable leaf spring means secured to the mounting surface and lying in part between the lever and each switch, the spring means having for each switch an arcuate cam portion extending generally transverse of the mounting surface into the path of the lever so that movement of the lever against the cam portion causes deflection of the spring means toward the mounting surface against the said element to actuate the switch.
Claim 4
Dependent Claim
172 words
A turn signal switch assembly comprising a support having a mounting surface, a manually operable turn signal lever pivotally mounted on the support for rocking movement between two limits in a path generally parallel to the mounting surface, right and left turn signal switches on the mounting surface adjacent the limits of the path of the lever for selective operation by the lever upon rocking movement thereof in either direction, an element of each switch being movable generally perpendicular to the path of the lever for switch actuation, and means for translating the lever motion to a switch actuating motion comprising yieldable leaf spring means secured to the mounting surface and lying in part between the lever and each switch, the spring means having for each switch an arcuate cam portion extending generally transverse of the mounting surface into the path of the lever so that movement of the lever against the cam portion causes deflection of the spring means toward the mounting surface against the said element to actuate the switch.
Claim 5
Dependent Claim
222 words
A turn signal switch assembly comprising a support comprising a housing and a circuit board having a mounting surface, a manually operable turn signal lever pivotally mounted on the support for rocking movement in a path generally parallel to the mounting surface, right and left turn signal switches on the circuit board mounting surface connected to conductors on the circuit board and positioned adjacent the limits of the path of the lever for selective operation by the lever upon rocking movement thereof in either direction, an element of each switch being movable generally perpendicular to the path of the lever for switch actuation, and means for translating the lever motion to a switch actuating motion comprising for each switch a yieldable spring lever secured to the circuit board by a fastener extending through the spring and the circuit board and by a tang on the spring formed to engage a cooperating aperture in the circuit board, the spring lever lying in part between the turn signal lever and the switch, each spring lever having an arcuate cam portion extending away from the mounting surface into the path of the turn signal lever so that movement of the turn signal lever against the cam portion causes deflection of the spring lever toward the mounting surface against the said element to actuate the switch.
