    • A magnetic field switch, comprising: A housing defining an interior space containing (a) a first permanent magnet, (b) a Hall Effect sensor, and (c) a switch device connected to the Hall Effect sensor and having a switching status varying in accordance with magnetic induction at the Hall Effect sensor; and a push-button reciprocally movably associated with the housing, the push-button including a second permanent magnet associated therewith, the push-button having a neutral position and an applied position. The first and second permanent magnets are spaced apart with the Hall Effect sensor and the switch device disposed therebetween. The first and second magnets have poles of the same polarity facing one another. The first and second permanent magnets each generate a magnetic field, the opposing magnetic fields meeting at a boundary region in the space between the first and second permanent magnets. In the neutral position of the push-button, the boundary region is positioned immediately above the Hall Effect sensor. In the applied position of the push-button, the boundary region passes through and activates the Hall Effect sensor.
    • 一种磁场开关,包括:壳体,其限定内部空间,所述内部空间包含(a)第一永磁体,(b)霍尔效应传感器,以及(c)连接到所述霍尔效应传感器并具有变化的开关状态的开关装置 按照霍尔效应传感器的磁感应; 以及与所述壳体相互可移动地相关联的按钮,所述按钮包括与其相关联的第二永久磁体,所述按钮具有中立位置和施加位置。 第一和第二永磁体与霍尔效应传感器间隔开,开关装置设置在它们之间。 第一和第二磁体具有彼此相同极性的极。 第一永久磁铁和第二永久磁铁各自产生磁场,相对的磁场在第一和第二永磁体之间的空间的边界区域相遇。 在按钮的中立位置,边界区域位于霍尔效应传感器的正上方。 在按钮的施加位置,边界区域通过并激活霍尔效应传感器。
