  • High pressure switch with isolated contacts
    Patent number: 7348509
    Abstract: A pressure switch employs electrical contacts isolated from pressure media. By employing a snap action blade in a snap over center configuration, it is possible to provide a hysteresis effect in which the switch actuates at one pressure and deactuates at a different pressure.
    Type: Grant

  • Variable analog output pressure switch
    Patent number: 7255009
    Abstract: A variable analog output pressure switch having a diaphragm attached to a plunger, the plunger controlling the amount of light detected by a photocell or photodetector, the photocell or photodetector outputting voltage roughly proportional to an applied pressure on the diaphragm.

  • Large actuation area switching device
    Patent number: 7250579
    Abstract: A large actuation area switching device includes a housing for holding a switch, means for compression and at least three slotted hinges. The slotted hinges create axes of operation such that a force applied to any point on the surface of the housing actuates the switch.
