Taper knob bakelite with moulded thread

What are taper knobs in Bakelite with moulded thread and what are they used for?

A taper knob made of Bakelite with a molded thread is a type of control knob commonly used in various electrical and electronic devices. Bakelite, an early form of plastic, is known for its durability and heat-resistant properties, making it ideal for use in electrical applications. The "taper" in the name refers to the shape of the knob, which usually narrows towards one end, allowing for precise control and easy grip. The molded thread indicates that the knob has an integrated screw-like structure on its inner side, allowing it to be securely fastened onto a corresponding spindle or shaft. These knobs are often found on older radio sets, electrical instruments, and various types of machinery, where they serve as user interfaces for adjusting settings like volume, frequency, or intensity.
