摘要： A pushbutton has a body including a barrel and a plunger longitudinally movable in the barrel. A plurality of longitudinally extending teeth on the plunger engage a plurality of longitudinally extending teeth on a rotatable ratchet coaxial with the plunger. The ratchet is spring loaded against the plunger. A rotatable electrical contact cup connected to the ratchet makes or breaks contact with a fixed electrical terminal in the body. The plunger teeth each include a driving face which causes rotation of the ratchet. The driving face has an angle from a normal to the longitudinal direction of the plunger wherein the angle is at least the arctangent of the coefficient of friction between the ratchet teeth and the plunger tooth plus the arctangent of the effective coefficient of friction between electrical contacts in the switch, plus a margin of safety greater than the arctangent of the effective coefficient of friction between other parts of the switch. The angle is up to about 30 degrees.

摘要： A push-button switch including a sliding member, a lock pin for locking the sliding member at a certain location, a heart cam including a lock cam along which the lock pin slides, and a movable stopper member, disposed at the heart cam, for holding the lock pin in a lock position as a result of cooperating with the lock cam or for unlocking the lock pin. The push-button switch incorporates a self-restoring function, wherein friction between the lock pin 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.
摘要翻译：一种按钮开关，包括滑动构件，用于将滑动构件锁定在特定位置的锁定销，包括锁定销滑动的锁定凸轮的心形凸轮以及设置在心脏凸轮处的可动止动构件，用于由于与锁定凸轮协作或解锁锁定销，锁定销锁定在锁定位置。按钮开关包括自恢复功能，其中在自动关闭状态期间锁定销和锁定凸轮之间的摩擦减小以减少解锁锁定销所需的力的量，从而减小螺线管致动电流，并且简化了致动结构，结果可以产生具有更长寿命和更小尺寸的更可靠的产品。
