    • A switch employing such magneto-sensitive switching element as, for example, reed switch or the like and generally used for crime prevention purpose with a high reliability, wherein the switching element is initially set in either one of its ON and OFF states by a permanent magnet disposed adjacent the element and rotatably about its central axis perpendicular to its longitudinal axis and such initially set state of the element is turned to the other state to actuate an alarm device when another permanent magnet mounted, for example, to a door approaches the rotatable magnet and magnetically varies initial relationship of the rotatable magnet to the element.
    • 采用这种磁敏开关元件的开关,例如簧片开关等,并且通常用于具有高可靠性的防止犯罪目的的开关元件,其中开关元件最初被设置在其ON状态和OFF状态之一 设置在元件周围并与其纵向轴线垂直的中心轴线可旋转的磁体,并且元件的这种初始设定状态转到另一状态以在另一个永久磁铁(例如安装在门上)接近可旋转 磁体并且磁性地改变可旋转磁体与元件的初始关系。
