ABSTRACT:
The present invention provides an apparatus for locking a gear train in high and low gear modes. A printed circuit board has first, second and third conductive pads, each of which are in electrical communication with a main circuit. A conductive clip having first and second contact portions is in slidable contact with the conductive pads, and is adapted to shift between a high gear position and a low gear position in response to actuation by an actuator. The low gear position is defined when the first contact portion contacts the first conductive pad and the second contact portion contacts the second conductive pad, and the high gear position is defined when the first contact portion contacts the second conductive pad and the second contact portion contacts the third conductive pad. The actuator is adapted to actuate the clip into the respective high and low gear positions in response to a signal from the main circuit and to cease actuation when the clip is at the respective high and low gear positions. The signal may, if desired, originate from a radio frequency transmitter. A gear selector is in mechanical communication with the gear train and the actuator, and is adapted to lock the gear train into the high gear mode when the clip is actuated into the high gear position and to lock the gear train into the low gear mode when the clip is actuated into the low gear position. Preferably, the clip is mounted to the gear selector and disposed between the gear selector and the printed circuit board. A method for locking a transmission into respective high and low gear modes is also disclosed.
