Pointer Knob


      • Material: Pointer knobs are typically made of plastic, metal or a combination of both materials. They need to be durable to withstand frequent use.
      • Design and Color: They come in various designs, shapes and colors to cater to different aesthetic preferences and functional requirements.
      • Markings: Many pointer knobs have markings on their surface to indicate the position or level of the adjustment. These markings can be numeric values, lines or symbols.
      • Grip: The outer surface of the knob usually has a textured or ribbed pattern to provide a better grip for users while rotating.


A pointer knob often referred to as a rotary knob or potentiometer knob is a common component used in electronic trainer kits and various electronic devices. It is designed to allow users to interact and adjust settings on electronic circuits, instruments and systems. The knob is typically mounted on a shaft of a potentiometer which is a variable resistor used to control voltage levels or adjust signal parameters.

  • Adjustment of parameters: The primary purpose of a pointer knob is to adjust various parameters in electronic circuits or systems. These parameters can include volume levels, brightness, frequency, gain and more By turning the knob users can increase or decrease these values.
  • User Interface: Knobs provide an intuitive and tactile way for users to intercat with electronic devices. This is especially useful in electronic trainer kits where users are learning about circuits and experimenting with different settings.
  • Analog control: Pointer Knobs are often used in analog devices where continuous adjustment is required. For example they are used to control the tuning of analog radios or the level of an audio amplifier.
