Abstract
A switch structure detects acceleration in a preselected direction such as, for example, along the pitch axis of an aircraft. The switch has a spring supported mass urged toward a stable centered position within the switch housing. Acceleration displaces the mass such that it trips a spring wire switch mechanism for controlling such avionic devices as the autopilot system of the aircraft. A pair of solenoid coils are wound around the spring mass system on opposite sides of the centered position of the mass. The switch may be preflight tested by successively energizing the solenoid coils to attract the mass toward the centers of the solenoid fields, thereby artifically displacing the mass against the spring wire switches.
