ABSTRACT:
A polarized bistable electromagnetic relay arrangement comprising at least two monostable instantaneous electromagnetic relay devices with a L-shaped yoke, a permanent magnet disposed between both relay devices so that one magnetic pole be magnetically connected by polar masses to both yokes of the relay devices and polar masses magnetically connect the other pole of the magnet to both blades whereas the magnetic circuits of both relay devices are designed so that the magnetic flux produced by one energized coil passes in series through both blades while superposing themselves to the magnetic flux produced by the permanent magnet.
