Model 639AS760 Miniature Inertia Switch

BC Systems Model 639AS760 miniature inertia switch for safe and arming applications reacts to preset G-force up to 1000 Gs.

Electronics Model 639AS760 miniature inertia switch reacts to a preset G-force to control an event, process or procedure by providing a direct signal when the Gforce has been reached. The switch may be set to respond to gradual or sudden acceleration and/or deceleration up to 1000 Gs. It is hermetically sealed and meets all applicable MIL Specs and DOD Standards appropriate for its use.

Measuring just .921″ high by .740″ in diameter without the wires, the switch is suitable for a variety of military aerospace and airborne applications such as would be found in satellite and missile systems. It operates by sensing the preset G-force limitation and then switching an event – or sequence of events – on or off depending upon function.
