Elma's New Industrial Illuminated Knobs Improve Visibility of Indicator Characters

FREMONT, California, Nov. 11, 2003 - Elma Electronic, a leading designer and manufacturer of rotary components and electronic packaging products, has announced a new line of Industrial illuminated knobs in various sizes and styles. The new line makes viewing of the indicator characters easier, even in darkness. This unique, new product range is a complete system to illuminate the figure dial under a knob. Illumination is accomplished via SMD LEDs on a flexible PCB strip inside a figure dial made of proprietary lightguide material. The illumination of the lightguide figure dial makes viewing of the indicating characters easier in all ambient light conditions, from a dark room to sunlight. Standard lightguide figure dial marking is available off the shelf, and customer-specific marking is available. All marking is done on the underside of the dial so there are no problems with character deterioration over time. This is as close to permanent print marking as possible. The Lighting Sets (lightguide figure dial and flexible LED strip) are designed to be used with the extensive array of standard Elma knobs in the 20 to 30 mm sizes in several styles. Additionally, the Lighting Sets can be used in conjunction with other manufacturer's knobs. Custom knobs are available with illuminated indicator lines, dots, or characters within the knob itself. As an additional option (for use with Elma's knobs), a knob skirt with single viewing window is available. The skirt's window highlights only one, illuminated character on the figure dial at one time for exact position selection. By allowing only one indicating character to show at any given time, there is little chance of confusing the switch or potentiometer setting. Standard LED colors are super-red, yellow, orange, green, blue and white. Mixtures of colors are available as a special order, as are colored lightguide figure dials. Pricing is in the mid $2.00 range in larger quantities and lead time is 2-4 weeks ARO.
