Abstract
A horn switch (40) for a vehicle steering wheel (20) includes a frame (50) for mounting to the steering wheel (20). The frame (50) includes a horn switch housing (56). A plunger (80) is associated with the switch housing (56). The plunger (80) is movable relative to the switch housing (56) between a non-actuating position and an actuating position. An actuatable cable (150) has a portion positioned in the switch housing (56). The actuating cable (150) includes first and second conductors (156, 158) for electrical connection to a circuit that when closed actuates a vehicle horn (30). The actuatable cable (150) has an expanded condition in which the first and second conductors (156, 158) are insulated from each other when the plunger (80) is in the non-actuating position. The plunger (80) when in the actuating position acting on the cable (150) to place the cable (150) in a compressed condition in which electrical continuity is established between the first and second conductors (156, 158) to close the circuit and actuate the vehicle horn (30).
