Abstract
An electrical receptacle of the twist lock type adapted to receive a photoelectric controller can be assembled into a luminaire without requiring the luminaire housing to be turned over and can be oriented in the field without use of tools. The receptacle is retained in an aperture through the housing by a snap ring having tabs on the inside edge which engage ledges in the body portion of the receptacle. The snap ring has leaf springs which hold the receptacle resiliently down against the housing. By lifting up the receptacle, keying pins and recesses in the receptacle and housing are disengaged and the receptacle may be turned to a different orientation.
