PURPOSE:To preclude the engine from starting if the safety belt is not outfitted in such a way that a belt switch is inserted into the circuit to connect through a timer to an ignition switch at a relay contact which is connected to a servo motor switch. CONSTITUTION:A time constant circuit 2, a voltage applying circuit 5, and a relay energizing circuit 6 are branched from a driving circuit 1 which is connected to a power supply terminal (a). A relay contact Rs is inserted to the circuit 1, a servo motor switch 8 is inserted through a ground terminal e, and an extension circuit 7, and its final end is grounded. While an ignition switch 9 is inserted through a set switch 20 to the power source B, which is branched to an indicating lamp 11, and connected to a ground terminal g, and then circuits 10, 13 are drawn out through a normal switch 12. The circuits 10, 13 are respectively connected through a belt switch 12 to power supply terminals a, b. The terminal b is connected to a coil Rc' of a relay contact Rs', and the contact Rs' is connected through an IC circuit, a tape circuit, a door switch 24, and a loudspeaker 25 to a switch 14. |
