Momentary Waterproof Switches – Instant Control, Lasting Protection
When quick response and absolute reliability matter, CPI’s Momentary Waterproof Switches deliver unmatched tactile precision and environmental endurance.
Built to perform in the toughest industrial and military conditions, these switches are fully submersible, maintaining seal integrity even during continuous operation and repeated activation cycles.
The design employs a rugged snap-action mechanism, encapsulated in either military-grade neoprene or industrial-grade Santoprene® housings.
This ensures dependable switching action across a wide range of temperatures and environments — from arctic cold to desert heat — with zero compromise on sealing or responsiveness.
Robust Design and Configurable Options
CPI’s momentary switches are available in multiple form factors — from low-profile pushbuttons to internal lever types — and can be supplied with custom cable terminations, coil cords, or mounted using CPI’s HS Series brackets, allowing easy installation on pipes, control arms, or vehicle frameworks.
Each switch is individually sealed to IP-rated waterproof standards, providing consistent performance in wet, dusty, or corrosive conditions.
Optional UL recognition is available upon request for compliant projects.
