ABSTRACT:
A submersible, touch-operated signaler including at least a pair of facially confronting, electrically conductive plates. Strips of resilient, nonconductive material are interposed between the plates to maintain a substantially preset spacing therebetween and to yieldably resist movement of the plates toward each other. The strips are disposed in a plurality of vertically aligned and spaced rows with vertically aligned fluid-draining passages therebetween. Rigid edge containment brackets along adjacent margins of the plates secure the edges of the plates against movement away from each other. Openings extend through a rear electrically conductive plate which align with the vertically oriented passages between the resilient strips to provide free vertical fluid flow into and out of the space between the plates. The touch-operated signaler operates on low voltage.
