Abstract
A switching device providing highly-reliable, frictionless, adjustment-free operation is described. Comprised of a comparatively small number of moving parts, the various aspects of the invention offer compact, cost-effective, reliable alternatives to their complex electromagnetic and costly solid-state counterparts. The main parts of the invention rely upon the principles of magnetic attraction and repulsion for the switching of a plurality of electrical contacts contained within the switching device. The flexibility inherent in the design of the invention permits the switching device to be configured in a variety of aspects, including the failsafe and latching designs described herein.
