Plain Black Rotary Encoder Control Knob

A plain black rotary control knob. This knob has a matte finish, with straight sides and a slightly concave top surface. There is no position indicator on the knob, so it is well suited to continuous rotation applications such as rotary encoders, tuners and multi-turn potentiometers.

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°.
