Waterproof Switch Products – Small and Tough

CPI Waterproof Switches have been solving tough engineering problems for over 50 years. Our switches perform flawlessly under severe environmental conditions where traditional splashproof, weatherproof, or wash-down resistant sealed switches do not survive.

Our switches are truly waterproof.  Used in tough military and industrial switch applications, we stock a wide variety of switch types, as well as an engineering team that can provide complete customization of your waterproof switch solution.

For reliable operation under exposure to water, oil, humidity, sand, dirt, vibration, shock, and temperature, CPI’w waterproof switches get the job done.

Momentary Switches

• Military grade (neoprene cover)
per MS39058

Maintained Contact Switches

Maintained contact pendants are available with the same options as the momentary units. Extremely durable construction in a compact package make these unique problem solvers.

Limit Switches - E1 Series

We offer many limit switch bracket designs, combining mounting and actuators into over 1,200 configurations. Our E1 Series brackets are all stainless steel and offer an economical and easily customizable limit switch solution. The E1 Series brackets can be coupled with most B Series basic switches, providing a broad array of application solutions.

Ball Switches - J4 Series

The original J4 Series ball switch has a patented ball carrier design, which prevents contaminates from jamming the ball, even in the depressed position.

Plunger Switches - J4 Series

Our J4 series plunger switches leverage our hardened actuators and field proven ball switch design, making them among the most rugged plunger switches in the world.

Waterproof Switch Panels

Waterproof - truly submersible switch panels feature CPI's rugged snap-action switches mounted on standard and custom stainless steel face plates. Resistant to solvents, oils, salt spray, UV, temperature cycling, these panels are ideal for long-term outdoor exposure, and can be mounted where others simply will not survive.
