Review on Innovative Components AN4C 5S221 Steel Insert by Adam Taylor

These innovative AN4C-5S221 1.38" Star Knobs work great on my Thumlers brass cup as a replacement for their standard wing nut combo and a Washer that is sometimes present is unwieldy. At first I thought they were too big for the handle diameter to clear the mounting bracket and drive rollers. They are a good size for my toggle switches as they have 1/4-20 threads. Be aware if you plan to use this or any other 1/4-20 knob on an Extreme Rebel 17 toggle switch, they will not work as the Rebel is made in China with a 6mm x 1.0 thread will be produced!
