ABSTRACT:
A method and apparatus for use in detecting non-parallel reed switch contacts, comprising digital circuitry for measuring the durations of contact bounces (open contact states) after the initial operation or closure of the reed switch contacts and a comparator stage; the output of the digital measuring circuitry is applied to the comparator stage which determines if the duration of any contact bounce is greater than or less than a digitally programmed reference number corresponding to a duration for an acceptable reed switch. Reed switch operating circuitry is also provided to operate and deactuate the reed switch contacts for a predetermined number of test cycles.
