Abstract: In a bistable electromagnetic relay composed of a U-shaped yoke provided with excitation coils, the arms of the yoke are inserted between the pole-pieces of a pivotally mounted H-shaped armature comprising a permanent magnet. A flexible strip attached to the armature carries two movable contacts which are applied against two stationary contacts in order to provide an electrical connection between the contacts. Only a very small proportion of the flexible strip performs a conducting function, there is no permanent connection between the strip and a fixed terminal, and a very short path is provided for current flow. The double-break action of the relay has the effect of reducing stray capacitance between open contacts.
