Abstract
A transfer switch for interconnection in a power supply system for an electrical load, such as a traffic signal, for selectively switching between primary and alternate power sources. The transfer switch includes a housing having a cover that is movable between open and closed positions for selectively providing access to an interior. An input receptacle is configured to engage an electrical connector of the alternate power source. The input receptacle is movable between a first position for facilitating engagement of the connector with the receptacle when the cover is open, and a second position when the cover closed. A selector switch is contained within the interior and interconnected with the load and the primary and alternate power sources. The selector switch selectively connects the primary power source and the alternate power source to the load, and the cover prevents access to the selector switch when the cover is closed.
