HaydonKerk environmentally and hermetically sealed switches
The HaydonKerk range of environmentally and hermetically sealed switches is designed for high reliability in extreme environments.
The sealed switches are filled with dry nitrogen and used in commercial and military aircraft, military ground equipment, space applications and industrial applications with harsh environmental conditions, such as gas turbines, thrust reversers, high-temperature valves and research instrumentation.
The switches are variously rated between -55 up to +400°C, as low as 1x10-8 atm cc/s leak rate, up to 1M cycles, and some are rated explosion proof. They are available with leaf spring, roller or roller lever actuation, and stainless/ceramic mounts when required, and the metal corrosion-resistant housings of some switches withstand most media and allow immersion in fluids such as synthetic hydraulic oils and jet fuels.
