Abstract

A magnetoresistive-based electronic switching apparatus and method. A housing having a first compartment contains switching electronics and a second compartment contains an actuation assembly. A barrier can separate the first compartment from the second compartment. An actuating magnet can be associated with the actuation assembly within the second compartment. The actuating magnet provides a magnetic field that can activate a magnetoresistive device located within the first compartment. Additionally, a magnetoresistive device responsive to the magnetic field of the actuating magnet can be utilized, wherein the magnetoresistive device located within the first compartment in association with the switching electronics provides a solid-state magnetoresistive switch thereof.
