  • Patent number: 4272746
    Abstract: A multipole, double throw relay includes a base with a coil and armature mounted at the center of the base. A terminal block with an L-shaped cantilever contact blade is mounted on one side of the coil. The contact blade extends up and over the coil, passes through a contact blade lifter affixed onto the armature and projects between a pair of contacts associated with a contact block assembly mounted on the opposite side of the coil. Operation of the coil causes the lifter to engage and move the flexible contact blade. The lifter has a lost motion action that prevents contact flutter and provides for a more efficient switching operation.

  • Patent number: 4270108
    Abstract: An improved two position control switch includes a spring biased pivoting armature with a projecting cantilever spring wire. The spring wire can be flexed in a direction transverse to the pivoting movement of the armature. The spring wire flexes to cooperate with a cam track thereby retaining the armature in one of two stable positions. Switching between positions occurs in response to pulse signals to the armature coil.

  • Patent number: 4255626
    Abstract: An improved four-way switch operated by a single manual push button at the end of a control column includes an axially extending shaft mounted to pivot on a stud. The shaft and stud are retained within a housing. An elastomeric washer with a frusto-conically shaped center passage is affixed on the shaft and engages the housing to radially bias the shaft and thereby maintain the shaft in proper axial alignment. Contacts are attached to the shaft and engage selected contacts on the housing when the shaft is pivoted. Guide slots in the housing cooperate with the pivotal shaft to control the direction of pivotal movement of the shaft.

  • Patent number: 4019165
    Abstract: An improved multiple-pole, miniature relay includes a housing with a coil, a core, an attached field piece, armature and armature return spring positioned therein. The armature engages a lifter which is restrained from movement within the housing except in a direction parallel to the axis of the core. The lifter is connected with a plurality of pivotal contact blades. One or both ends of the blades have contacts thereon adapted to engage with contact pins depending upon the mode of pivotal movement. Electric contact is maintained through the blades by mounting the blades upon additional contact pins.
