CPI Switches Help Military Vehicles Survive

Military hardware never stops evolving, because threats never stop evolving. Yet proven technology like CPI thermal and waterproof switches continue to be designed into modern hardware. It comes back to survivability and endurance, and we pretty much own that.

Whether for flight or for ground programs, we offer a variety of switch and sensor products that are qualified to the demanding requirements of the aerospace and military industries.

CPI Thermal Switches for the Military

CPI has supplied reliable thermal switching solutions to various major aircraft manufacturers worldwide for applications in ECS, APUs, compressors, galley equipment, and much more. Our most common aerospace designs have been qualified per RTCA DO-160C and MIL-STD-810.

One interesting aspect of our thermals is their ability to detect cold as well as hot. With programmable set points down to -40F our switches have been used to activate heating systems that preserve electronics operation in cold weather. Our switches won’t freeze up or suffer from sticky contacts thanks to our proprietary design and materials.

General Product Features – Thermal Switches

  • Hermetically sealed designs available
  • Glass-sealed MIL connectors
  • Setpoints available from 0F to 1750F (depending on model)
  • Thread and surface mount designs
  • Various probe lengths
  • Meet the requirements of RTCA DO-160C

Waterproof Switches for the Military

Due to their compact size and low profile, our Waterproof Momentary Switches are a popular choice for push-to-talk (PTT), laser sighting, and field night vision applications. These same switches mounted in our robust bracket & actuator designs have provided solutions for tank turrets (M1 Abrams), engine kickdown (HMMWV), and various limit switch applications for the HMET programs. Our most demanding application yet, cab position indication for the LTAS chassis, employs our J4 Plunger Switch capable of withstanding high vibration. These units still function with the plunger encased in hardened sand and/or ice.

 Waterproof Switches for ground applications 

  • Completely waterproof – rated to IP68 / MIL-STD-810
  • Hardened stainless steel actuators (J4 Plunger Sw.)
  • Cold temperature rating down to -61F (Neoprene covered switches)
  • Electromechanical endurance over 5 million cycles
  • Various actuator and mounting configurations
  • Fits in tight spaces

Customizations Available

  • Custom wire lengths
  • Sealed terminations include MIL-compliant connectors
  • Wire harnessing and abrasion protection
  • Customized mounting / actuators

CPI Switches Started out with the US Military

Back around 1945, our first thermal switches were actually produced for the US military. We’ve come a long way since then, but the standalone reliability of our products has remained our “raison d’etre.”
