Abstract
Abstract An adjustable duplex receptacle which contains four bus bars is disclosed. One of the bus bars is attached to a spring-loaded leg which, with the use of an adjustable, rotatable pin, can be caused to contact either of two of the other bus bars. The pin may be locked into one position by means of a locking mechanism.
