1. A shock sensor comprising:

  • a) a housing;

    b) a reed switch having a glass capsule defining an axis with at least one reed disposed along the axis and the capsule having a first end and a second end, wherein the reed switch is mounted within the housing;

    c) a first abutment fixed to the housing in proximity to the capsule first end and facing away from the capsule;

    d) a second abutment spaced axially away from the capsule, and spaced from the first abutment;

    e) a magnet slidably mounted within the housing between the first and second abutments;

    f) a load-responsive means for biasing the magnet, said means being mounted between the first abutment and the magnet and adapted to bias the magnet away from the first end of the reed switch while the shock sensor is not subjected to a selected accelerative force; and

    to allow the magnet to approach the first end of the reed switch when the sensor is subjected to a selected accelerative force.
