Abstract
An omni-directional inertia switching device is presented. The inertia switching device comprises a housing having a conically shaped upper portion for retaining a ball member within the housing. The ball member is supported by a flat spring having a star shaped opening therethrough. The flat star spring is comprised of electrically conductive material. A lower contact member and the conductive flat star spring are separated by an insulator except for a central opening corresponding to the portion of the flat star spring where the ball member is located. Further, the flat star spring and the lower contact member have terminals which extend from the housing for connection with an external device. The device of the present invention is actuated when a preselected amount of inertia force causes the ball to overcome the biasing forces of the flat star spring bringing the flat star spring and the lower contact member into electrical contact. The inertia switching device may be ganged to define a digital switch accelerometer, wherein each switch is configured for an incremental measurement; e.g., increments of 1 g.
