Abstract
A Christmas Tree formed of collapsible sections of trunk and branches with electrical lights mounted in sockets on each branch. Electrical conductors run from a portable supply cord joining the base of the trunk through the trunk and branches with the individual sections of the tree joined together by plug and socket fittings that form both mechanical and electrical connection of the joined members. The top section of the trunk is fitted with a spring-biased member that rests against a ceiling to hold the trunk in a vertical position, with the base of the trunk resting on the floor or other support surface. A multi-pole switch is fitted on the portable supply cord for switching various combinations of tree lights.
