Abstract

PURPOSE: To add a hydraulic pressure so as to be uniformly dispersed over the whole area by bringing a plurality of spacers into contact with an electrode plate when a conductive rubber sheet is pressed by a hydraulic pressure of wave, water flow or the like. CONSTITUTION: The peripheral parts of a conductive rubber sheet 2 and an insulating plate 3 arranged opposite to each other are integrally fixed with watertightness. An electrode plate 5 is fixed to the inner surface of the insulating plate 3, and a plurality of spacers 6 area arranged at a prescribed pitch on the inner surface of the conductive rubber sheet 2 with a prescribed space from the electrode plate 5. Consequently, a hydraulic pressure can be added so as to be uniformly dispersed over the whole area. Since the touch pressure can be thus held constant regardless of water depth, a precise time counting can be performed.
