Transistor Radio Volume Control Potentiometer & 21mm Red Thumbwheel Knob, 5K

This is a new, 5K linear pot with a 21mm red plastic thumbwheel attached as often seen on small radios. The switch contacts open when the knob is turned fully anti-clockwise. The wheel thickness measures 2.4mm.

The pot body diameter is 16mm. The track tolerance is +/-20% with maximum power of 0.1W. The switch maximum rating is 12V, 0.5 Amp. The fixing screw for the knob is a cross-head type, but the design is such that you can fit it using a small 2mm flat blade screwdriver without any trouble.
