ELMA ELECTRONIC Bell-shaped knobs for electronic switches in the 3, 6, 9, and 12 o’clock indicating positions come in hard or soft touch finishes. The ‘bell-shaped’ or ‘top-hat’ designs are ergonomic and space saving. Devices accept standard, ‘pan European’ D-shape for 6mm shafts with a 4.5mm flat. Regardless of the orientation of the D-shape end, the indicator lines or dots come in the 4 position options and are available in blue, white, or custom colors.
