Waterproof Switches for Harsh Duty Applications

Momentary Switches & Pendants
Originally developed for military applications, our line of robust Waterproof Momentary Switches and Pendant Switches are unique problem solvers. Their compact, durable form factor has been used by hundreds of customers in Military, Industrial and Commercial applications.
Waterproof Microswitch Technology

CPI takes Micro-Switch Technology further with a rugged sealing design that is truly waterproof (submersible) not just splash proof. The patented ball carrier design of our Ball Switches and Plunger Switches maintain seal integrity through switch activation in harsh duty environments.

Draw-Wire Linear Position Sensors For Multiple Environments
CPI Sensors Now Intrinsic Safety Rated Both ATEX and IEC-EX Certified
Draw Wire Sensors For Hydraulic Cylinders, Accumulators & Industrial Position Sensing

CPI’s high endurance draw wire Linear Position Sensors use a patented linear to rotary converter that provides excellent responsiveness and high accuracy when coupled to a short rod magnetostrictive transducer as the core sensing technology. The assembly is extremely durable and vibration resistant with models covering stroke lengths to 20 meters.

The new CTU Series provides low cost, highly accurate industrial grade position measurement in a small form factor  for light duty applications up to 3 meters.

Control Products’ first sales were to the US government in military applications and switches designed by CPI continue to be used extensively in military equipment. Today CPI provides creative control solutions to a diverse group of markets.
