Abstract
A sealed reed spring switch in which a single pair of contacting springs carries two or more electrically insulated conducting paths. The electrically conductive, magnetically responsive springs are coated with an insulating material at least on opposing surfaces over which two or more distinct conductive coatings are formed. Two circuits such as a telephone tip and ring circuit, for example, may be simultaneously controlled by a single sealed two-path switch unit.
