Black Control Knob With Concave Cap
Black Control Knob With Concave Cap
This distinctive control knob features a tall profile with elegantly tapered fluted sides that narrow towards a smooth cylindrical base. The defining characteristic is its concave top surface, which creates a subtle recessed area that provides comfortable finger placement and tactile feedback during operation.
The knob's fluted exterior offers excellent grip, with vertical ridges running the full height of the tapered section before transitioning to the smooth lower portion. Without any position indicator markings, this knob is particularly well-suited for rotary encoder applications where continuous rotation is required, making it an ideal choice for volume controls, parameter adjustments, and other encoder-based interfaces in audio equipment, electronic instruments, and control panels.

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°.
