Inertia Switch is the world leader in all mechanical gravity switches for aerospace applications.
Because of the sensitive ITAR regulated nature of parts of the Inertia Switch product line, Allied International provides international OEM and aftermarket support for Inertia Switch acceleration Sensitive Devices. The product line consists of a large variety of acceleration sensitive switches, safety and arming devices, shock sensors, and recorders. Inertia Switch’s patented "Magnetically restrained Seismic System" represents a significant advance in motion sensing.
APPLICATIONS: Only Inertia Switch's magnetically restrained devices meet the latest RCTA vibration requirements for ELT Emergency Locator Transmitters. Other aerospace applications included control of CVR and CDR (Cockpit Voice Recorder and Cockpit Data Recorder) for commercial aircraft, activation of fire extinguishers and erasure of IFF data on crash landing for helicopters, arming of missiles and torpedoes, and parachute deployment for satellites. IS limit switch applications are for military and other severe applications such as for military helicopters to determine whether there is weight on the landing gear or whether all the various access ports and doors are closed. On large commercial aircraft where the conditions are not as severe this function is typically performed by purely electronic sensors.
