Abstract
The present invention provides an improvement to a coupling device which allows for quickly changing electrical fixtures without rewiring. The quick change mounting fixture comprises a combined electrical and mechanical two-piece male and female fastening device. A female receptacle plate is mounted to a standard ceiling or wall-mounted electrical junction box, and a male tap support plate which also functions as a fixture support may be selectively rotatably mounted to the female receptacle plate. Rotation of the male tap support plate through a predetermined angle with respect to the female receptacle plate automatically aligns respective live and neutral electrical contacts supported on the respective plates. The improvement comprises a ground spring electrical contact mounted to the male plate which engages the suitably grounded female plate before the male and female electrical contacts of the respective plates become electrically engaged through the rotation of the male plate relative to the female plate. The resilient force of the spring contact tends to urge the respective plates apart and therefore helps to insure snug electrical connections between the respective live and neutral electrical contacts on the male and female plates after they have been rotated into alignment.
