    摘要： A magneto-motive bistable switch comprising a hermetically sealed contact container having at least one pair of electrical contact points and a free floating ferro-magnetic contactor. An electro-magnetic coil encircles the contact container which is placed within the magnetic flux of two spring loaded permanent magnets. The switch is electrically tripped by a dc trigger pulse thus energizing the coil to thereby magnetically polarize the ferro-magnetic contactor which is thereupon magnetically attracted towards one permanent magnet respectively thus establishing a bridging relationship with at least one pair of electrical contact points. The switch is manually operated by exterior pressure on a switch knob which changes the distance between permanent magnet and contactor which is thereupon attracted to the respective closer permanent magnet thus executing the switching operation. The switch may function as an ac overload circuit breaker when a contactor with a preestablished curie point is used to indicate a sudden power surge. By attaining the curie temperature it loses its ferromagnetic qualities and thereupon falls off the contact points due to the force of gravitational attraction and breaks the circuit. The inventive idea postulates a manually and electrically operable ac and dc switch and overload circuit breaker which functions directionally fully independent (except for the ac overload circuit breaker) is absolutely fireproof and operates within a temperature range of 1,000* Centigrade. The switch comprises a hermetically sealed contact container embodying at least one pair of electrical contact points a free floating ferro-magnetic contactor. An electro-magnetic coil encircling the contact container and the contact container are placed together within the magnetic flux of two spring loaded permanent magnets. The switch is electrically tripped by a dc trigger pulse thus energizing the coil that thereby magnetically polarizes the ferro-magnetic contactor which is thereupon magnetically attracted towards one permanent magnet respectively thus establishing a bridging relationship with at least one pair of electrical contact points. The switch is manually operated by exterior pressure on a switch knob thus changing the distance between permanent magnet and contactor which is thereupon attracted to the respective closer permanent magnet thus executing the switching operation. As an ac overload circuit breaker a contactor with preestablished curie point is applied to indicate a sudden power surge by attaining curie temperature thus losing the ferro-magnetic qualities thereupon falling off the contact points due to the force of gravitational attraction thereby breaking circuit. Resetting is either manually or electrically accomplished.

    摘要翻译： 一种磁动双稳态开关，包括具有至少一对电接触点和自由浮动铁电接触器的气密密封接触容器。 电磁线圈包围放置在两个弹簧加载的永磁体的磁通内的接触容器。 开关由直流触发脉冲电气跳闸，从而使线圈通电，从而使铁磁接触器磁化极化，铁磁接触器分别磁性吸引到一个永磁体，从而与至少一对电接触点建立桥接关系。 开关由开关旋钮上的外部压力手动操作，该开关旋钮改变永磁体和接触器之间的距离，从而吸引到相应的更近的永磁体，从而执行开关操作。 当使用具有预先建立居里点的接触器来表示突然的电力浪涌时，该开关可以用作交流过载断路器。 通过达到居里温度，它失去了铁磁性质，由于重力的作用而使接触点脱落，从而断开电路。

    摘要： A hinge has two leaves held together with a hinge pin and each leaf is provided with a recess opening out of the back face thereof. A magnet is completely contained within the recess on the one leaf, while a magnetic reed switch is completely contained within the recess of the other leaf. When the hinge is closed the magnet actuates the magnetic reed switch, but not when the hinge is open, so that it is possible to maintain surveillance over a door from a remote location. Both the magnet and the switch are completely concealed when the door is either opened or closed so that it is impossible to detect their presence or to tamper with them. No special preparation of the jamb or door is required to install the hinge.

    摘要： An electric switch mounted as an attachment to a radial readout gauge, including a permanent magnet carried by or forming a part of the gauge pointer and which is movable over a graduated scale of the dial face. The magnet of the pointer is capable of moving into a position for closing or opening an electric circuit controlled by the switch. The electric switch includes a knob which is rotatably adjustable over the dial face and which includes a switch located to be actuated by movement of the magnet to a position in proximity thereto for either closing or interrupting the electric circuit controlled by the switch.

    摘要： A remotely actuable switch includes a housing defining a cavity having first and second thermally separated chambers, each enclosing a pair of spaced electrical contacts and each having an associated heating element. An electrically conductive fusible element occupies one of the chambers and electrically bridges the spaced contacts therein. To activate the switch the first heating element is activated to melt the fusible element, allowing a Lorentz force resulting from an applied external magnetic field and from current passing between the bridged contacts to expel the melted fusible material from the first chamber into the second chamber. A helical passage may be used as an alternative to a cavity with discrete chambers.
