Abstract
Movement of an inertia mass (4) from a rest position as a result of acceleration or deceleration in excess of a given threshold value causes a hinge-like assembly (8) having two parts (9 and 10) to pivot between two overcenter positions on either side of a center position in which the two parts (9 and 10) occupy a common plane to thereby cause movable electrical contacts (14 and 15) forming part of the hinge-like assembly (8) to engage or separate from further electrical contacts (31 and 32).
