ABSTRACT:
Apparatus for proximity magnetic switching wherein magnet assemblies are used in combination with magnetic reed switches by placement of the reed switch axis in a magnetic field null position which is shifted or unbalanced by proximation of certain magnetic materials to actuate the magnetic reed switch. In particular, such proximity magnetic switch is made weather proof and entirely sealed from its environment by molding the magnet assembly and reed switch assembly in fixed orientation within a potting compound which then exposes an actuating surface for sensing the presence of a magnetically permeable material.
