  • Patent number: 5865303
    Abstract: An electrical rocker switch having a clam-shell like in which a rocker is pivotally mounted. A unitary multi-function operating assembly fabricated from spring stock materials which operates as an over-center spring to establish two rest positions for the rocker. A trifurcated second end of the operating assembly provides springs to urge the contact assembly into intimate engagement with the boss on the underside of the rocker. Cross-members of the operating assembly bear movable contacts which selectively engage fixed contacts on the housing to complete external electrical circuits connected to the operating assembly and fixed contacts. An additional housing can be placed about the clam-shell like housing to seal the switch from the environment.
    Type: Grant

  • Patent number: 5836443
    Abstract: An electrical rocker switch having a clam-shell like in which a rocker is pivotally mounted. A unitary multi-function operating assembly fabricated from spring stock materials operates as an over-center spring to establish two rest positions for the rocker. A bifurcated or trifucated second end of the operating assembly provides springs to urge the contact assembly into intimate engagement with the boss on the underside of the rocker and provide for receiving an electrical conductor. Cross-members of the operating assembly bear movable contacts which selectively engage fixed contacts on the housing to complete external electrical circuits connected to the operating assembly and fixed contacts. An additional housing can be placed about the clam-shell like housing to seal the switch from the environment.

  • Patent number: 5684272
    Abstract: An in-line cord ground fault circuit interrupter has a tripping relay whose various components are an integral part of the GFCI housing, instead of being self-contained. The front cover of the housing has the necessary bosses, guide slots, and screw holes for mounting of all the mechanical and electrical elements of the relay. The rear cover serves as a water resistant enclosure and holds the relay elements in position across the width of the housing. The relay's movable contact arms are attached directly to the printed circuit board of the GFCI. The relay armature is located by ribs on the front cover and is trapped in position when the relay coil and frame assembly is pushed over it using guide slots in the front cover. The armature has integral arms extending to each side wherein each arm has an actuating cam on its end. Gripping ribs and strain relief ribs are placed at the cord entrances to the housing with a chamber formed therebetween.

  • Patent number: 5680287
    Abstract: An in-line cord ground fault circuit interrupter which contains within a common housing the sensing unit and the tripping relay usually found separately packaged at a remote location. The fixed contacts are mounted on fixed contact arms mounted adjacent one surface of a printed circuit board with the movable contacts mounted on movable contact arms mounted adjacent the second surface. The tripping relay operates an armature between an open and a closed condition and by cams on the arms of the armature opens and closes the movable contacts with the fixed contacts. The two portion housing allows the components of the interrupter to be mounted on one portion of the housing which also supports the line and load conductors making assembly of the rear housing portion to the front housing portion easy.
