专利汇可以提供Overhead electrical switching device专利检索,专利查询,专利分析的服务。并且An electrical switching device for use at remote locations such as room ceilings comprises a switch mounting plate having an electrical push button switch mounted thereto with an actuating plate confronting the push button and mounted for movement toward and away from the button, the actuating plate having guide rods projecting outwardly therefrom and extending within registering guide sockets in the switch mounting plate. Stops are provided at the end of the guide rods to contain the rods in the guide sockets, and coil springs are positioned about each guide rod between actuating plate and mounting plate to urge the actuating plate away from the mounting plate. The electrical switch device is mounted in a junction box within the room ceiling, and a cover plate mounted flush with the ceiling surface bears flushly against the actuating plate, the springs, guide rods and guide sockets cooperating to align the movable actuating plate parallel to the cover plate and parallel to the local surface of the ceiling. The switching device is actuated by an operator on the floor by depressing the actuating plate toward the mounting plate with a pole. The invention is particularly useful in buildings with movable wall partitions where it is necessary to control electric power flow to the wall partitions.,下面是Overhead electrical switching device专利的具体信息内容。
