Aerospace & Military Industries

Whether for flight or for ground programs, we offer a variety of products that have been qualifie

d to the demanding requirements of the aerospace and military industries.

CPI has supplied reliable thermal switching solutions to various major aircraft manufacturers worldwide for applications in ECS, 

APUs, compressors, galley equipment, and many more. Our most common aerospace designs have been qualified per RTCA DO-160C and MIL-STD-810.

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.
