PURPOSE:To prevent a battery from dying, by providing a third contact point to be connected to the battery only when a starter contact point is connected with a battery contact point. CONSTITUTION:A starter circuit is provided with a register short relay 8 as a switch mechanism including a coil 8a connected to a register short contact point R as a third contact point in an ignition switch 3 and a contact point 8b connected in series to a coil 4a of a starter relay 4. Accordingly, even when a starter contact point in the ignition switch is leaked because of dew condensation, etc., the third contact point is hardly simultaneously leaked, and therefore no feed circuit of a starter motor is formed, thereby causing no rotation of the starter motor. Thus, a battery may be prevented from dying. |
