PURPOSE:To prevent a waste of electric power due to forgetting switching off by providing an electronic circuit to control concentrically an operation of a plural automobile load and a reset circuit to reset the electronic circuit when closing touch switches and ignition switch. CONSTITUTION:Upon turning an ignition switch 10 on, a reset circuit 18 generates a reset pulse to reset FF1-3 once through OR gates 15-17. If a touch switch 4, for example, is turned to ON position here, FF1 puts out power to a relay coil 21a through an amplifier 25 and a diode 28 and energizes it to turn a contact 21b on. A fog lamp 24 lights up accordingly. Then, from turning a touch switch 5 to ON position, relays 20, 21 operate likewise to light a tail lamp 23, and FF1 is reset; from turning a touch switch 6 to ON position, a head lamp 22 also lights up, and FF2 is reset then. |
