Abstract
Abstract A reed switch comprising a first reed of conductive magnetic material and a second reed of conductive non-magnetic material mounted in cooperating spaced relation to said first reed and a cooperating pair of magnetic operators mounted in spaced relation to said first and second reeds and said reeds being positioned between said pair of operators, and including a third operator cooperating with the pair of operators to influence one or the other of said operators to shift said first reed into a first mode or a second mode and latch said first reed in said mode.
