<p>A push-button switch including a sliding member (2), a lock pin (6) for locking the sliding member (2) at a certain location, a heart cam including a lock cam along which the lock pin (6) slides, and a movable stopper member (5), disposed at the heart cam, for holding the lock pin (6) in a lock position as a result of cooperating with the lock cam or for unlocking the lock pin (6). The push-button switch incorporates a self-restoring function, wherein friction between the lock pin (6) and the lock cam during an auto-off state is reduced to decrease the amount of force required to unlock the lock pin, thereby reducing the solenoid actuating current, and simplifying the actuating structure, as a result of which a more reliable product with a longer life and a smaller size can be produced. <IMAGE></p> |
