ABSTRACT:
A sealed two-plate swimming pool touchpad construction that is unaffected by pressure, in which a resilient, compressible, non-conductive spacer material such as rubber tubing is seated in an array of spaced recesses or grooves on the inside face of the rear plate to insulatively space a conductive, flexible front plate from the rear plate. The front plate is joined and sealed in watertight fashion to the rear plate around the array of grooves and spacer material. Conductive portions of the inside face of the front plate are flexed into switch-closing/signaling contact with conductive portions of the inside face of the rear plate between the spacer material when a swimmer makes contact with the front plate.
