ABSTRACT:
A universal T.V. channel knob has a channel indicator skirt slidably receivable on a cylindrical, molded synthetic plastic knob shaft and relatively attachable thereto in an infinite number of rotative positions to provide for universal replacement usage. A metal, radially depressable slide pin is provided for securing the dial skirt in adjusted rotative position with respect to the knob shank with only minimal projection inwardly along its mounting shank, thereby minimizing any possibility of interference with fine tuner knob assemblies and the like that may be coaxially arranged in close proximity behind the T.V. channel knob assembly.
