Collet knobs from Sifam Instruments are functional knobs that are manufactured in nylon with a fine textured matt finish. The Collet knobs, available from Switches Plus Components , come in a wide range of sizes with a variety of accessories. All knobs are available in black or grey as standard, but other colours are also available.
The main criterion in the design of Collet knobs and accessories has been function, styling handling and simplicity of use. Accessories, including caps, pointers, figure dials and nut covers have been designed to push-fit into the Collet knob body to give added versatility.
All Collet knob bodies, caps, pointers and nut covers are also manufactured in nylon with a finely textured matt finish. Transparent figure dials are manufactured in polycarbonate, and coloured dials are manufactured in nylon. Collets, housings and nuts, fitted into the knobs during manufacture, are of brass and accommodate a wide range of shaft lengths and bush lengths.
Two colour soft-touch Collet knobs: Two colour soft-touch Collet knobs meet the needs of the general industrial and audio market for a soft touch finish as an alternative to the traditional hard surface finish. The 2 shot process, using polypropylene and thermoplastic elastomer, allows the indicator line to be moulded rather than printed. The standard body colour is black and the line, when specified, is white. Other colour combinations are available to order. Both items can be used as a dual concentric set.
