Knobs are rotary adjustment devices designed to adjust manual input to an electrical or mechanical system turned or grasped by a human operator. These devices provide tactile and visual features for human-machine interface (HMI) controls, along with solid grips for adjustable fasteners. They may be colour-coded, comprise indicators (dots, notches, or lines), or numbered and are selected by type, shaft size, material, style, and diameter.
We house various knob types from the enclosure, storage, and material handling family, including spinners, control knobs, wing knobs, ball knobs, multiple lobed knobs (star knobs), and knurled finger knobs. They are made of various materials with a wide range of applications.
Factors When Selecting a Knob
There are varieties of knobs, and choosing the correct one for a specific application depends on the type of environment in which it will be used. For instance, environments with extra moisture, grease, or oils are not favored for polished ball knobs and vice versa.
Different styles of Knobs
As mentioned above, they are available in various shapes and styles for industrial, machinery, and assemblies. Some of the most common include:
These feature flat heads, are large with round knobs, and are designed to be easily operated by one hand. They also comprised a small hand to facilitate easy turning.
Control knobs, also called instrument, electronic, or electrical knobs, are designed to control or adjust electronic or electrical devices. They offer instruments or machines an exact adjustment along with controlled circular motion levels.
They come in various sizes, are round in shape, and are ideal for directional movements such as up-down and left to right. They are also used for control handles and levers. In addition, they also function as a pull or tightening.
Wing knobs have an ergonomic and simple design with a wing-shaped head. They are used in high torque applications, fingertip control, and low adjustment tightening.
They are also referred to as star knobs, and are ideal for applications that require secure grips. Furthermore, their unique style is preferred for turning, adjusting, and clamping applications with strong grips.
These knobs are designed for applications where operators are in contact with damp environments. They feature grooved outer edges and are ideal for non-slip firm grips.
