Ball knobs are a common place component used for many applications, and have a classic design which has stood the test of time. They are designed to fit snugly into the palm of the hand for comfortable usage. They are available in a wide range of materials and can be fitted by either pressing into place or via a thread.
Push pull knobs are ideal in situations where a switching function is needed, and provide more robust option than a standard switch. The mushroom shape and waisted shape variations of these are designed to allow the fingers to fit easily underneath making them more ergonomic where the knob would be in frequent use, while those with a concave top provide a comfortable thumb rest.
All handles and knobs supplied by Berger Tools are of excellent quality, and are stocked in the UK.
