  • Underwater zoom switch
    Patent number: 5089671
    Abstract: Conductive pads are disposed in a housing which consists of a degassed, non-compressible, electrically insulating fluid. One of the pads is mounted on the underside of a push-button, and the push-button is surrounded by a flexible membrane which closes one end of the housing. When the push-button is pressed, the fluid between the conductive pads is displaced, and the membrane stretches sufficiently to accommodate the displaced fluid.
