ABSTRACT:
A non-water-tight touch pad for swimming competitions mounted partially submersed on the finishing wall of a swimming pool. The pad includes two plates located in front of each other. The front plate is perforated plastic material and is loosely inserted in a frame consisting of channel sections on the four sides and movable towards the metal back plate.
Resting between the two plates, a plurality of parallel metal strips are mounted on the back metal plate but remain insulated from the back metal plate while connected to each other. A number of conductive springs shaped as seagull wings are welded on each parallel strip. These springs are mounted perpendicularly to the strips and act as spacers between the two plates and act as electric movable contacts between strips and the rear plate as soon as any pressure is applied on the front plate.
A plurality of plastic levers are mounted on the upper side of the touch-pad permitting a vertical force exerted by a backstroke swimmer to be tranferred to the sensitive front plate.
