  • Shock sensor employing a spring coil for self-test
    Patent number: 6335498
    Abstract: A reed switch based shock sensor provides for passing electrical current through the coil spring used to bias the shock sensing magnetic mass. The spring is wrapped around the reed switch, allowing the coil spring to act as an electrical coil. The coil generates a magnetic field of sufficient strength to cause the reed switch reeds to attract and so close the reed switch, thus allowing the reed switch to be tested without the addition of a test coil.
