1. A multi-directional momentum-change sensor, comprising:

  • a base member adapted to be able to be fixedly mounted to a surface;

    a column member, having a first end and a second end,wherein said first end is fixedly coupled to said base member;

    a substantially discoid electrical-contact-array assembly, having a first end and a second end, and having a plurality of electrical-contact surfaces disposed radially about the outer surface of the substantially discoid assembly,wherein said first end is fixedly coupled to said second end of said column member; and

    an inertial switching assembly, comprising;

    a pivotable boom member, having a proximal end and a distal end, said proximal end being the end closest to said substantially discoid electrical-contact-array assembly, and having a longitudinally disposed channel,an electrical contact fixedly disposed at said proximal end of said boom member,an spring member configured to resist extension, having a first end and a second end, fixedly coupled on its first end at or near said proximal end of said pivotable boom member, said spring member adapted to be able to be extendable to a length of at least approximately equal to that of said longitudinally disposed channel when predetermined stretching force is applied,a weighted, sliding electrical contact, fixedly coupled to said second end of said spring member, adapted to be movable along said longitudinal channel, and electrically in continuous communication with said proximal-end electrical contact, anda distal-end electrical contact fixedly disposed at the end of said longitudinally disposed channel, at said distal end of said boom member, said distal-end electrical contact positioned such that said weighted, sliding electrical contact can electricallycouple with said distal-end contact when said spring member is extended;

    wherein said inertial switching assembly is adapted to be pivotably coupled about the longitudinal axis of said substantially discoid electrical-contact-array assembly; and

    wherein said inertial switching assembly'"'"'s proximal-end electrical contact on said boom member is adapted to make surface-to-surface electrical contact with at least one of said plurality of electrical-contact surfaces, depending on the pivoted position of said boom member relative to said substantially discoid electrical-contact-array assembly.
