Description Photo shows two sets of kit number 628-0061 The CTC Knob Kit is to be used to dress up rotary switches which are used around the layout or when building a CTC panel. The CTC Knob kit will give the rotary switches the look and feel of the control panel knobs used by the real railroads for many years. The knob which has a spring insert will press fit on the shaft of a rotary switch that has a flat or D shaped shaft. The knobs and plates are molded plastic in a silver color. Decals are provide for the numbering of the plates. Plates are reversible with Switch on one side and Signal on the other side. Plates will need to be painted black then lightly sanded to expose the raised silver areas. CTC Knob kit instruction sheet: ctc-knob-instructions
