    • 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 90° 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.
    • 刮水器驱动装置包括由电动机旋转的驱动齿轮,承载在可附接到电动机或电动机齿轮上的盖的引线框架,并且包括分立的导电迹线的圆周方向,以及可旋转地安装在盖上并承载周向的驻车开关桥 间隔开的触点,每个可以在导电迹线上滑动,以在驻车开关桥与驱动齿轮接合并由驱动齿轮旋转时打开和关闭到驱动马达的电路。 每个触点承载在从形成园区开关桥的径向延伸臂的周向突出的梁上。 驱动齿轮承载的驱动销啮合连续的臂,使驻车开关桥90°转动驱动齿轮的每转,使不同的触点与导电迹线电连接,而不需要引线框架或停放开关的额外工具 桥本身
