DEFINITION
Classification: 318/497
(under subclass 495) Subject matter in which means are provided for connecting the several armature or primary windings in series circuit relationship with respect to each other at one time and in parallel circuit relationship with respect to each other at another time; or for connecting two or more of the windings in parallel circuit relationship with respect to each other and for, simultaneously, connecting two or more of the windings in series circuit relationship with respect to each other.
(1) Note. One of the windings in a parallel connected group may constitute one of the windings in the series connected group as, for example, where one armature or primary winding may be parallel connected windings.
