ABSTRACT:
A linear vehicle transmission switch (10) has first and second interfitting housing members (12, 14) each having an electrically conductive lead frame (12m) insert molded in electrically insulative material and formed with exposed segments (12f) of lead frame material along linear tracks. An elongated actuator (16) is slidably received in a channel of one of the housing members and is disposed along a side of the tracks. A paddle (16b) extends transversely across the tracks. Ribs are disposed between tracks and dimensioned to limit rotational movement of the paddle. A pair of stabilized contact switches is disposed on the paddle for each track. The housing members have a selected camber to lower the force required to move the actuator. The lead frames are plated to reduce contact resistance and improve wear.
