Helicopter Rotary Wing aircraft require specially engineered switches with higher vibration tolerances and pressure sensitivities, which Hydra-Electric have been creating for decades. As this field has evolved into higher stress capabilities, greater flight-time requirements, more vertical take-off applications in jets and military craft applications, Hydra Electric has met the challenge and maintained their distinction as the specified switches of choice for these following manufacturers. | Bell Helicopter | V22, A609, Bell 430, Bell 412, Bell 407 | | McDonnell Douglas (Boeing) | AH-64 | | Agusta | BA609 | | MD Helicopter | MD 600, MD 530, MD 520 | | Sikorsky | S76, S92 | | | |  |
