Submersible push buttons and underwater switches, sealed against continuous water exposure.
Underwater and submersible controls require interfaces that operate under sustained water pressure with absolute seal integrity. RNC solid-state piezo technology activates through solid metal surfaces with no moving parts, no seal penetrations, and no pressure-vulnerable components. RNC piezo switches are built to operate exactly this way underwater.
Submersible push button, underwater switch, IP69K sealing.
A submersible push button has to keep working after being underwater for hours or days at a time, not just survive an occasional splash. RNC solid-state piezo switches have no moving parts, no button shaft, and no panel hole for water to find, so there is no mechanical seal that can fail under continuous water exposure.
Sealing is rated to IP69K, the same standard used for high-pressure washdown testing, and the fully potted metal construction is built for submerged installations in pools, fountains, and tanks. An underwater switch built this way keeps sensing reliably whether the panel is dry, splashed, or fully submerged, without the sensitivity drift or corrosion that affects conventional buttons in constant wet service.
Because activation is force-based rather than capacitive, standing water on the panel does not register as a touch, and there is no membrane or gasket to degrade with prolonged wet exposure. That combination of a sealed metal surface and no moving parts is what makes the switch suitable for equipment that spends most of its service life below the waterline.
