Tuning knobs

2 March 2011 Switches, Relays & Keypads

The STAR-KNOBS are available in the two diameters of 33 and 41 mm and in two installation versions. The surface-mounted version’s main body is slightly inclined towards the internal axis for ergonomic operation. A 3 mm high ring can be illuminated here if required. The flush-fitting version is characterised by almost flush assembly using a recessed ring. The knob is illuminated by means of a ring between the recessed ring and the lid of the knob. The supplier can offer the latter as standard with and without a finger recess. The knob itself is available in two versions, smooth or with a knurled rim, in the OKW knob colours of volcano (NCS 5502-G) and nero (NCS 9000-N).

For the actual illumination, OKW relies on power-saving LED technology. The PCB for this is included in the range of accessories and has been fitted with six white LEDs. It is mounted using a snap-in technique in a special bracket, with which the knob on the front panel is also secured. This bracket also prevents the light from radiating backwards into the appliance. Two openings also guarantee effective dissipation of the heat that arises through the power loss of the LEDs and the necessary series resistors. The bracket is also responsible for holding the potentiometer, which is secured using a ring nut. The necessary 5 V power supply is not included in the scope of supply.

Different luminous colours can be obtained through the knob or the ring itself. Four translucent colours are available as standard: diamond (white), ruby (red), sapphire (blue) and emerald (green). It is also possible to obtain non-illuminated versions of the STAR-KNOBS if required.
