ABSTRACT:
A polarized miniature relay incorporates a rod-shaped armature pivotally mounted at one end and axially arranged within the coil member with its free end projecting between two oppositely magnetically polarized pole shoes coupled with two opposite poles of a quadripole permanent magnet. A flux plate is connected to the other poles of the permanent magnet and has an aperture which supports the armature for pivoting motion in contact therewith. A very low reluctance for the magnetic circuit results in the magnetic flux paths of the relay.
