Abstract: An acceleration switch array having at least two acceleration switches. Each acceleration switch includes a substrate, an anchor attached to the substrate, an electrically conductive mass disposed around the anchor and secured to the anchor by a spring assembly which permits movement of the mass relative to the anchor, and a plurality of electrical contacts positioned at circumferentially spaced positions around and outwardly from the mass. These electrical contacts are aligned along at least one orthogonal axis. A resistor array is electrically connected between the electric contacts of each acceleration switch for each orthogonal axis so that, upon contact between the mass and any of the electrical contacts, an electrical resistance is presented at an output terminal that is unique for each electrical contact for each acceleration switch.
