ABSTRACT:
A universal magnetic switching assembly for detecting relative movement between first and second members, the universal switching assembly including, a flux directing device for selectively directing a majority of applied magnetic flux, such that an externally applied magnetic field cannot be used to defeat the magnetic switch assembly. The magnetic switching assembly also including at least one tamper switch to detect application of an external magnetic field.
