<p>PURPOSE:To enable remote control that can easily be remotely controlled using the conventional single signal line by providing various operation switches in a steering wheel. CONSTITUTION:An operation section 10 provided in a steering wheel and a receiving section 50 provided at a car body side are connected using a single signal line 40. The operation section 10 is comprised with an input switch section 20 for remote operation and a signal voltage conversion section 30 that converts the voltage applied from the receiving section to the signal line into different voltage levels corresponding to the operation status of the switch 20 and the receiving section 50 is comprised with a voltage level decision section 60 that decides the voltage levels on the signal line 40 converted by the signal voltage conversion section 30 and a feeding section that feeds power to a specific and intrinsic load depending upon each voltage level corresponding to the decision signal of the voltage level decision section. Since remote control is made possible using the single line like this, the number of sliding contacts is reduced to one and the wiring between rotary and fixed sections is simple.</p> |
