CAR-MOUNTED SWITCH DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the space for a switch unit and facilitate its mounting and replacement. SOLUTION: A car-mounted switch device includes a plurality of switches 1 each of which serves as a wireless IC tag to work without power supply, in which communications between the switches 1 and a switch control unit 3 are conducted in the form of short range radiocommunication distinguishable by RFID, and the switches 1 are driven using the electric wave from the switch control unit 3 as the electric energy. This can be established without wiring of electric wires between the switches 1 and the switch control unit 3 to lead to suppression of the space required. and also facilitate changing the layout of the switches 1 and designing a variation of the layout extremely. Even if a rotating operation of the steering is conducted, the radiocommunications between the switches 1 and the switch control unit 3 will occur smoothly. COPYRIGHT: (C)2005,JPO&NCIPI
