K1 Metal Rotary Knob Series
The K1 series of metal rotary knobs from Elma are made from robust aluminium and are highly engineered to fit D-Shape and round rotary switch shafts from both Elma and other manufacturers.
Designed to fit shaft diameters of 3mm, 4mm, 6mm, 1/8” and 1/4” The K1 series is fixed via the use of an Allen screw. The surface is anodised creating a hard-wearing, scratch-resistant and electrically non-conducting surface.
The K1 series is available in a range of 8 standard styles in black or natural silver colours. Optional red, gold, green, light and dark blue colours are also available upon request. If your project requires a unique colour or design please contact us as Elma are able to create a vast array of customised knobs.
