This is really the fanciest, best feeling knob we\’ve ever seen. Using this knob sort of reminded us of driving along the Amalfi coast in a perfectly restored \’65 Porsche – meaning we really, really liked it. We hand selected the best knobs for your project in different sizes and varieties. This one\’s the Solid Machined Metal Knob – 1\”. It has a nice, weighted feel that spins easily and doesn\’t sacrifice versatility or comfort for durability. It feels solid, much more so than a knob with a plastic inside and metal shell. There\’s a grooved rubber band that fits in an indented section of the knob for easy grip and a clear white arrow on the top so you know where you\’re turning to or from. Best of all, a small set screw is pre-installed, so this beautiful knob works on both our Potentiometers and Rotary Encoder making it incredibly useful whether you\’re rotating to a position with a potentiometer or you just want something that rotates all the way around.
