The illuminated control knob from Mentor makes it possible to see the exact setting of the knob, regardless of the ambient light.
The design of the light guide sets can be used for suitable knobs made of plastic or aluminium with a diameter between 20 and 30 mm. They consist of a flexible printed circuit board with an LED assembly and a transparent light guide, both of which are slipped onto the shaft of the switch or potentiometer.
The scaling, which can be adapted for customised specifications, is on the bottom of the light guide, so that the need for smudgeproof properties is only secondary.
The available LED colours - red, green, yellow, orange, blue and white - can be combined by the developer not only for applications for night-time designs, but also to create daylight applications to match the individual corporate design.
Two separately controlled LED groups can display defined settings or warning notices. An optional plate with a window is available for use with Mentor knobs.
This allows the active settings to be targeted and illuminated, so that it is virtually impossible to interpret the display incorrectly.
