Smooth Castle Top Plastic Control Knobs

Smooth Castle Top Plastic Control Knobs

This knob has a smooth, tapered side with a matte finish. A slightly triangular position indicator on the top extends as a line down the side to the base of the knob to provide precise positional information for the user. A ring around the base and voids around the top edge of the knob provide additional colour accenting for applications where colour identity are important such as lighting or mixer channels.

Hole Type

D Shaft Hole

A D-shaft knob features a hole with a D-shaped cross-section, having one flat side and the rest round. This configuration ensures that the knob fits snugly onto the shaft, preventing any slippage and provides absolute psoitoning of the position indicator.

The flat side of the hole aligns with the flattened side of the D-shaft, providing precise control and secure attachment. This type of hole is commonly found in knobs used in audio equipment, industrial controls, and automotive applications.

This type of hole dictates the angle of the position indicator, relative to the flat of the D shape. This is measured in degrees of rotation being either 0°, 90°, 180° or 270°.
