More often than not, the importance of peripheral car parts such as the radio control knob is understated if not completely ignored. We only realize its importance after noticing that it's broken and the entire car stereo becomes useless altogether. Don't worry because among thousands of replaceable car parts, the radio control knob is probably the easiest one to change. But, replacing the knob isn't really the problem ? the problem is in choosing the right knob for your car stereo. Fortunately, here's a guide that will help you explore some of the most common radio control knobs, and hopefully will help you decide on which one to buy.
Compared to standard models of radio control knobs, the collet knob is designed to integrate function and versatility into one. The collet knob has a soft touch finish unlike other types of control knobs that have hard surfaces. In addition, the collet knob uses polypropylene and thermoplastic elastometer in order to mold the markers rather than simply printing it. Commonly, collet knobs are colored in black and white which interchanges between the marker, the body and/or the surface.
In terms of durability, the push-on knob is the name of the game. Push-on knobs are created using a two-shot molding procedure that allows creating the two parts simultaneously without the need for assembly. It has a hard touch finish due to polypropylene content that gives it more durability compared to other knobs.
The slider knob is specially designed to provide the user with the ease of control. However, while a slider knob is perfect for that aspect, it takes a lot of space. This is because the slider knob requires occupying at least three inches of a horizontal line to set the control parameters and visual aids. Moreover, slider knobs are available in soft touch and hard surface models.
