PURPOSE: To eliminate the need for an interconnection cable and a connector or the like by incorporating a reception circuit to a lever switch main body, a reception antenna to a lever and a transmission circuit and a transmission antenna to a steering wheel.
CONSTITUTION: A reception circuit 4 is incorporated to a main body 2 of a lever switch 1 operating a light device or the like of a vehicle and a reception antenna 5 is incorporated to a lever 3. A transmission circuit 7 and a transmission antenna 8 are incorporated to a pad of a steering wheel 6, and a remote control switch 9 is provided to the surface of the steering wheel 6 and a horn switch button 10 is provided to both sides of it. A power supply section of the transmission circuit 7 is connected in parallel with the horn switch 10. While the horn switch 10 is not in operation, a power supply voltage subtracting a voltage drop by the horn relay coil is applied to the transmission circuit 7. Thus, no exclusive use power supply line is required. The reception antenna 5 and the reception circuit 4 are connected directly and the transmission antenna 8 and the transmission circuit 7 are connected directly and then no coaxial cable or the like is required and the cost of the control device is reduced.
