PROBLEM TO BE SOLVED: To prevent a burglar and to provide convenience of maintenance of a good interior environment by connecting an ignition contact to an igniting device in series, connecting a third contact to a first contact in series, and connecting the first contact to the ignition contact in parallel. SOLUTION: A bypass circuit 7 is connected to a main circuit 6, in which an ignition contact 4 and an ignition device are connected to a battery 2 in series, even when the ignition contact 4 is turned off. In the bypass circuit 7, a relay coil 8 is connected between the positive electrode and the negative electrode of the battery 2, and between the relay coil 8 and the positive electrode, a first contact 9 and a second contact 10 are connected is series, while the first contact 9 is connected to the ignition contact 4 in parallel. Between the relay coil 8 and the negative electrode, a third contact 11, which is actuated when a side brake is applied, is connected. In addition, a return pressing button 12 is connected, and a self-hold circuit 13 consisting of relay means is constructed. |
