Abstract (en)
[origin: US4475093A] A polarized electromagnetic relay has two L-shaped yokes with a permanent magnet disposed therebetween. Each yoke has a long leg and a short leg with a coil wound around the long legs of the yokes. The long leg of a similarly L-shaped armature is also disposed between the long legs of the yokes and the armature is pivotally mounted at its short leg so that the free end of the long leg of the armature executes switching movements between the short yoke legs and forms a rectangle in combination with the yoke arrangement. The armature may be mounted centrally or single-sided with respect to the yoke legs for monostable or bistable switching behavior of the relay. The compact arrangement of the yokes and armature permits a number of contact elements to be disposed beneath the coil at both sides of the long armature leg, with the armature causing movement of spaced spring contact elements for making and breaking with corresponding fixed contact elements.
