Twin break transfer switch

摘要

An electrical transfer switch for providing electrical power from either one of two sources of electrical power to a load, and characterized by at least a pair of spaced power contacts disposed on a base which contacts are electrically connected to different sources of power; a load contact on the base and interconnected with a load; an electrically conductive bridge pivotally supported intermediate the ends thereof on the base for rotation between different angular positions as power for the load is transferred from one power source to another power source.
