Abstract
A gas damped deceleration switch is calibratable to enable the switch to perform in a desired manner in response to deceleration pulses of various magnitudes and durations. A vacuum which is generated upon initial movement of a mass away from a rest position toward an activated position restrains movement of the mass away from the rest position. The vacuum is adjustable by means of an adjustable flow of gas into the vacuum. Adjustment of the flow of gas into the vacuum adjusts the degree to which the vacuum is generated for a given rate of movement of the mass away from the rest position, and thereby adjusts the magnitude and duration of a deceleration pulse required to overcome the gas damping forces resisting movement of the mass upon generation of the vacuum.
