Abstract
A remotely controlled relay having a lever and a link, both of which being driven by a bistable polar electromagnet device. The lever is also manually operable. The lever drives a switch circuit to open and close while the link operates the main-circuit opening-and-closing assembly. The display provided on the lever indicates the open and closed conditions of the main circuit. A current is supplied to the coil of the bistable polar magnet device from an external circuit and magnetizes the plunger such that the plunger moves through a stroke between a first and second positions. When the plunger arrives at the center of its stroke while the plunger is moving from the first position to the second position, the lever causes the micro-switch to switch from the a first contact position to a second contact position. When the plunger arrives at the center of plunger stroke while the plunger is moving from the second position to the first position, the lever causes the micro-switch to switch from the second contact position to the first contact position.
