摘要： A matrix relay is formed with a plurality of latching relays arranged in a matrix and mounted on a base (1) of an electrically insulative material. Each of the latching relays comprises an excitation coil (50), permanent magnet (40), a pair of first and second fixed 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 to the excitation coil (50) so as to be movable in response to energization of the coil by current of selective polarity between close and open positions of the fixed and movable contacts. A plurality of the armatures of the latching relays arranged in a row of the matrix are assembled into a single armature block to be mounted on the base as a single unit. The armature block comprises a single pair of first and second supporting members made of an electrically conductive material. All of the first movable springs and all of the second movable springs of the latching relays of the armature block are connected respectively to the first and second supporting members mechanically and electrically, so that 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 of the matrix relay would be useful to small-size the matrix relay without complicated fabrication process.

摘要： PURPOSE:To provide a compact and economical optical waveguide switch without necessitating a liquid injection/exhaust device and having a high switching speed by providing a gap variable means varying the width of a gap continuing to the groove of an intersection part between an optical waveguide for input optical signal and an optical waveguide for output optical signal. CONSTITUTION:An electromagnet is constituted of a soft magnetic 8 and a coil 7, and magnetic field is generated when current is allowed to flow through the coil 7, and a soft magnetic hooked cross shape beam 10 is attracted, and a variable gap member 13 attached to the beam 10 is moved. When the current is not allowed to flow through the coil, the gap 11a becomes smaller than the gap of the groove 5 by being compressed by the variable gap member 13, and a silicone oil 12 is gathered to the gap 11a by a capillary phenomenon, and becomes the state 12a of the silicone oil to form a reflection state. When the current is allowed to flow through the coil 7, the variable gap member 13 is moved upward, and the gap becomes the gap 11b larger than the gap of the groove 5, and the silicone oil 12 is gathered to the groove 5 by the capillary phenomenon, and becomes the state 12b, and a transmission state.
