Abstract
A sensor comprising: an inertial mass movable from a first position to a second position in response to a acceleration (deceleration) signal of predetermined amplitude and duration; electrical contacts and a conductor on the inertial mass for indicating that the inertial mass has moved to the second position; an electrical conductor, reactive with other elements of the sensor for generating an electro-magnetic force tending to dampen the motion of the inertial mass; and a magnetically attractive element or magnet for biasing the inertial mass towards the first position.
