    • The timer switch comprises a setting member for setting a desired period, an escape wheel provided with saw-shaped teeth, a rack interposed between the setting member and the escape wheel for disengaging the setting member from the escape member while the setting member is operated and engaging the setting member with the escape wheel while the escape wheel turns, an anchor provided with a pair of claws, which is disposed so as to be opposed to the escape wheel, an electromagnetic member which begins to rock the anchor intermittently when the setting member is operated, so that the claws of the anchor are alternately engaged with the escape wheel. When the setting member is moved either along or about its axis, the escape wheel is disengaged from the setting member and the electromagnetic member begins to rock the anchor intermittently so that the claws of the anchor are alternately engaged with the escape wheel. Consequently, the escape wheel turns intermittently to engage the setting member with the escape wheel through the rack. As a result, the setting member moves intermittently at predetermined timings and by predetermined pitches.
    • 定时器开关包括设置期望周期的设定部件,设有锯齿状的擒纵轮,设置在设定部件和擒纵轮之间的齿条,用于在设定部件动作时使设定部件脱离脱离部件, 在擒纵轮转动的同时使设定构件与逃生轮接合,设置有与擒纵轮相对设置的一对爪的锚固件,当设置构件 操作,使得锚的爪交替地与擒纵轮接合。 当定位构件沿其轴线或其轴线移动时,擒纵轮与设定构件脱离啮合,并且电磁构件间歇地开始摇动锚杆,使得锚的爪与擒纵轮交替地接合。 因此,擒纵轮间歇地转动,使设定构件与擒纵轮通过机架接合。 结果,设定构件以预定的时间间隔以预定的间距移动。
