Abstract:
A wiper drive apparatus includes a drive gear rotated by a motor, a lead frame carried on a cover attachable to the motor or motor gear and including a circumferentially of discrete conductive traces, and a park switch bridge rotatably mounted on the cover and carrying a circumferentially of spaced contacts, each slidable over conductive traces to open and close a circuit to the drive motor as the park switch bridge is engaged by and rotated by the drive gear. Each contact is carried on a beam projecting from a circumferentially of radially extending arms forming the park switch bridge. A drive pin carried on the drive gear engages successive arms to rotate the park switch bridge 90Â for each revolution of the drive gear to bring a different contact into electrical connection with the conductive traces without requiring additional tooling for the lead frame or the park switch bridge itself.
