Abstract
A velocity change sensor comprises a body having a passage within which is a movable sensing mass normally maintained in an inactive position by a magnetic biasing force, but which is movable from its inactive position to an operating position in response to acceleration exceeding the biasing force. Movement of the mass is fluid damped to delay its movement to the operating position for a period of time during which the acceleration must exceed the biasing force.
