1. A roller band acceleration sensor comprising:

  • (a) an elongated housing of insulating material;

    (b) a reset end cap of conductive material disposed on a first end of said housing;

    (c) an actuate end cap of conductive material disposed on a second end of said housing;

    (d) two rollers disposed within said housing between the first and the second ends of said housing;

    (e) a band of conductive material looped in a generally S-shaped fashion about said two rollers, said band having a reset end connected to said reset end cap, an actuate end connected to said actuate end cap, and a breaking means for breaking electrical conduction between said reset end cap and said actuate end cap when said housing is subjected to a predetermined shock acceleration, said breaking means defining a reset portion of said band between said reset end and said breaking means; and

    (f) insulating means for insulating said reset end cap and said reset portion from all remaining portions of said band when said breaking means breaks electrical conduction between said reset end cap and said actuate end cap.
