Black Aluminium Rotary Control Knob with Silver Indicator
Black Aluminium Rotary Control Knob with Silver Indicator
This distinctive rotary control knob features a sleek black aluminium outer shell with a precisely machined silver bevelled edge that catches the light beautifully. The circular cap displays a crisp silver position indicator line that extends from the centre to the edge, providing clear visual feedback of the knob's position. The knob's cylindrical body maintains consistent proportions across all sizes, creating a professional appearance that complements modern audio equipment and electronic devices.
The knob's surface presents a uniform black finish with the silver elements creating an elegant contrast. The splined shaft fitting system uses an internal insert that securely grips 6mm splined shafts, making it particularly well-suited for high-quality audio amplifiers, mixing consoles, and precision electronic equipment where reliable shaft engagement is essential. The substantial feel and precise construction make this knob ideal for applications requiring frequent adjustment and professional presentation.

Hole Type

Splined Hole
Knobs designed for splined shafts have holes with multiple grooves or ridges that correspond to the splines on the shaft. This splined hole creates a very tight and secure fit, preventing any movement between the knob and the shaft.
The position indicator can be placed in any of 18 different directions, in increments of 20°
The ridged interior of the hole ensures a strong connection, capable of handling high torque and frequent adjustments without the risk of slippage.
A control knob with a splined hole will not fit onto a round or D typ shaft.
