摘要：A matrix relay is formed with a plurality of latching relays arranged in a matrixand mounted on a base (1) of an electrically insulative material. Each of the latchingrelays comprises an excitation coil (50), permanent magnet (40), a pair of first and secondfixed contacts, and an armature (73) carrying a pair of first and second movable springs(72a,72b) each providing movable contacts. The armature (73) is magnetically coupled tothe excitation coil (50) so as to be movable in response to energization of the coil bycurrent of selective polarity between close and open positions of the fixed and movablecontacts. A plurality of the armatures of the latching relays arranged in a row of thematrix are assembled into a single armature block to be mounted on the base as a singleunit. The armature block comprises a single pair of first and second supporting membersmade of an electrically conductive material. All of the first movable springs and all of thesecond movable springs of the latching relays of the armature block are connectedrespectively to the first and second supporting members mechanically and electrically, sothat two row paths for electrical signals common to the latching relays arranged in the

row of the matrix are provided. This simplification of the structure and electric circuit ofthe matrix relay would be useful to small-size the matrix relay without complicatedfabrication process.
