## Description

Plastic knob for potentiometer with 6 mm shaft, ideal for precise level control in electronic and industrial equipment. It has compact dimensions of 15x17 mm, firm grip on the shaft for stable adjustments, easy-to-handle finish, blue color for quick identification on the panel.
The plastic rotary knob is intended for potentiometers with a 6 mm shaft and replaces or complements the adjustment knob of a rotary potentiometer. It is used in audio equipment, power supplies, amplifiers, controllers, and in electronics projects where adjustment must be made easily by hand and the potentiometer position should be visible at a glance.
The knob measures 15 x 17 mm and is made of plastic. The shaft diameter it is designed for is 6 mm, a common size for panel-mounted rotary potentiometers.
Among its main features are the black body with a ribbed side surface, which provides a secure grip when turning, the blue top section, and the blue indicator that shows the adjustment position. The knob is a passive mechanical accessory and does not require power.
The knob fits rotary potentiometers with a 6 mm shaft diameter and can be used for new projects or to replace damaged knobs.
Specifications:
Product type: Rotary knob for potentiometer
Material: Plastic
Potentiometer shaft diameter: 6 mm
Color: Blue
Dimensions: 15 x 17 mm
Use:
Before installation, check that the potentiometer shaft has a diameter of 6 mm.
Turn the potentiometer shaft to the desired end position, for example minimum, then align the knob indicator with the corresponding mark on the panel.
Push the knob onto the shaft until it reaches the desired position, without applying excessive force.
Do not force the knob onto a shaft with a different diameter and do not turn the shaft beyond its mechanical limits.
Leave a small gap between the knob and the panel so that the knob can rotate freely without rubbing.
To remove it, pull the knob straight up, without rotating it past the end of the potentiometer travel.
