<p>PURPOSE: To surely release a door lock at the time of a collision and simplify the circuit structure by connecting a collision detecting sensor to the unlocking circuit section of a door locking circuit in parallel with a door lock switch. CONSTITUTION: When a door lock switch operation knob 19 is operated to the lock side, an action piece 4a is operated to lock a door. When a hand is removed from the door lock switch operating knob 19, it is returned to the neutral position. When the operation knob 19 is operated to the unlock side, the action piece 4a is connected to an unlock side contact point from a moving contact piece to release the lock. When the hand is removed from the operation knob 19, it is returned to the neutral position. When a vehicle collides, a collision detecting sensor 22 is operated, a ball 27 enters between contact points 24a, 25a from a recess 26, both contact points 24a, 25a are short-circuited, and a door locking mechanism section is operated.</p> |
