Abstract
A switch including: a first body having holes located at a longitudinal position; a movable second body having a concavity corresponding to the holes; a retaining ball positioned in the holes and corresponding concavity for restraining the second body from movement relative to the first body; an elastic element disposed on the body; a mass disposed on the elastic element, the mass moving the elastic element upon an acceleration event; and first and second electrical contacts positioned on the body such that when the acceleration event has a predetermined magnitude and duration, the mass moves past the longitudinal position to permit the retaining ball from releasing from the holes, thereby permitting the second body to move towards the first and second electrical contacts; wherein the second body includes a conductive portion for closing an electrical circuit between the first and second electrical contacts.
