  • Miniature relay
    Patent number: 4739292
    Abstract: A miniature switch has superior ability to switch small signals with high efficiency. A capsule encloses the switching contacts, the moving contact being provided with a magnetically permeable armature. A pair of magnetic pole pieces extend into the capsule and form an air gap closely adjacent the armature. When a magnetic field is applied across the air gap between the pole pieces, the armature is actuated and initiates the switching action.

  • Miniature relay
    Patent number: 4609897
    Abstract: A relay is disclosed which is sufficiently miniaturized for use in a DIP socket. It employs tapered switching contacts for obtaining maximum deflection with a given force. Novel adjustable fixed contacts are employed. The solenoid portion is designed to avoid offset adjustment problems and maximize the efficiency of magnetic coupling.
