Waterproof Switches

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

CPI 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 customisation of your waterproof switch solution.

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