Soft cover. Condición: Very Good. Softcover pamphlet published in the early 20th century by the great electric company, Westinghouse. 17 pages + List of Circulars in Force, January 1, 1907 at the end of the volume. Illustrated throughout. With a saddle-stapled binding and four hole punches alongside the left edge of the volume. This publication looks at the Unit Switch System of Multiple Control made by Westinghouse. It features many illustrations, including parts & different views of the switch system. With sections on Resistance, Reverser, Line Switch Cut-Out, Master Controller Cut-Out and Reset Switch, Junction Boxes, Train Lines, etc. The edges of the front cover are discolored. With bumped corners, chipped crown/foot of the spine, and wear from rubbing on the covers and spine. Wear also includes a torn spine 1 at the crown, 2 at the foot and with several staple holes near the left side of the book, each going all the way through the interior, cover to cover. The corners of the book by the crown and foot of the spine are creased. Ex-library with minimal markings, limited to a sticker on the front cover with a reference number written in ink. No other marks or writing in the volume. Interior is clean and in good condition. With light toning from age and discoloration at the gutter between pages 10-11 due to rusting staples of the binding.
