Application notes

Hermetic limit switches

to detect and indicate the position of rotor components, such as the blades or pitch control mechanisms. The limit switches are hermetically sealed to prevent the entry of liquids, dust, or gases.

Limit switches offer

SIDE STICKS CONTROLLERS

as a lateral control element that replaces the traditional cyclic stick to pilot the helicopters.
