History

No other developer of switches and sensors has been so integral to the growth and innovation of the aerospace industry.

For more than 65 years, Hydra-Electric Company’s dedication and commitment has been to provide its global customers with the most advanced electro-mechanical solutions for monitoring and control of pressurized operating systems.

Hydra-Electric started its business in 1948 in the heart of the aerospace development community in Burbank, California. Hydra began working closely with Lockheed Martin's engineering facility in the 1950’s providing them with pressure switches for many of their early aircraft, such as the U2 and the SR71 Blackbird. Hydra-Electric’s first product was actually not a pressure switch but a fuel tank valve for aircraft built by General Dynamics. The fuel tank valve allowed the aircraft to distribute fuel evenly between the two aircraft wings, so that it was balanced during flight.

Our first pressure switch was designed for the Lockheed T-33. The switch is quite similar to today’s designs, as it incorporated a negative rate disk spring and many other common features found in today’s units.

Hydra-Electric switches were also chosen for America's first major jets, such as the P80, F86, F100, F104, B52 and B707. In the 1960’s, switches were created for the X15, F4, DC8, DC9 and most NASA space flights, including the Apollo moon missions. Since 1970, thousands of systems were developed in global military and commercial aerospace applications. Today, Hydra-Electric switches are widely used on military, commercial, business jet and helicopter operating systems; turboprop, turboshaft, turbofan and rocket engines; weapons systems, ships and numerous industrial and commercial applications.

More recently, Hydra-Electric has expanded its product offering to include temperature, pressure and multi-function sensors based on breakthrough technology.

Today, Hydra-Electric products are widely used on military, commercial, business jet and helicopter operating systems; turboprop, turboshaft, turbofan and rocket engines; weapons systems, ships and numerous industrial and commercial applications.
