Abstract
A shock sensor has a housing with two portions. A first portion resiliently engages a reed switch which has staple formed leads. A second portion extends adjacent one of the reed switch leads and has modular components which permit consistent shock-sensing results to be obtained from reed switches of varying sensitivity by selection of appropriate components. The second portion is a closed-ended hollow tube in which a bobbin with a centrally located guide bar is inserted. A first disk extends outwardly from the guide bar. A self-test coil is positioned on the bar between the first disk and a second disk. A biasing spring extends between the closed end of the tube and the magnet, which is mounted on the bar. The magnet is abutted against a second disk which extends from the bar. The second disk positions the actuation magnet with respect to the reed switch when it is in its non-actuated position. By substituting different bobbin and the actuation springs, shock sensors are easily created which achieve identical functions with reed switches of varying amp turn requirements for actuation.
