DEFINITION

Classification: 338/132

(under subclass 130) Subject matter wherein the resistors are of the angularly adjustable contact type, and are disposed behind one another with the contact or element rotation occurring about a common axis; together with an actuating shaft extending along this axis, or with the operating shafts of the respective resistors extending along this axis and including coupling structure to enable these shafts to rotate in unison.
