Abstract
A weather-tight air conditioning disconnect switch has both plastic and metal enclosure components for low cost assembly. The exterior components include a metal case and cover whereas the interior non-electrical components are plastic-molded. One such molded plastic dead-front shields the electrical terminals within the enclosure and contains instruction and caution indicia integrally-formed on the exterior surface during the plastic molding forming process. ON - OFF indication of the switch is achieved by the orientation of the switch handle with the switch handle receiver.
