Tailored for switches with three, six, nine, and 12 o’clock positions, the company’s bell-shaped knobs come in hard or soft touch finishes and feature a unique shape that is said to be both ergonomic and space saving. The knobs accept standard, pan European D-shape 6-mm shafts with a 4.5-mm flat. Regardless of the orientation of the D-shape end, the indicator lines or dots come in the four-position options and are available in blue, white, or custom colors. ELMA ELECTRONIC INC., Fremont, CA.
