The sensor includes a linearly movable mass including two sections and spring means urging one of the sections into operative engagement with means including an actuating element. The sensor also includes means releasably securing the two sections together and means releasing the securing means when the two sections have moved a predetermined distance against the urging of the spring. The two sections may be rollers of a rolamite unit. A flexible band extends around a portion of the two rollers. One example of a use for such a sensor is in an air bag safety restraint system.
