Abstract
A vehicle collision detecting apparatus is provided which includes a casing having an opening, a base support member fitted into the opening of the casing to retain a movable contact and a stationary contact, a mass member biased by a spring in a first direction along a given path of travel defined in the casing to urge the movable contact into constant disengagement from the stationary contact, and a stopper member formed on the base support member to restrict movement of the mass member in the first direction urged by the spring to hold the movable contact at a given contact gap away from the stationary contact. The mass member is responsive to acceleration caused by impact acting on the apparatus to move in a second direction opposite the first direction against a spring force exerted by the spring to engage the movable contact with the stationary contact to provide a signal indicative of occurrence of a vehicle collision.
