Elma's New Bell-Shaped Knobs are Space Saving and Ergonomic

FREMONT, California, Feb. 10, 2004 - Elma Electronic, a leading designer and manufacturer of rotary components and electronic packaging products, is expanding its electronics knob line with new "bell shaped" or "top-hat" designs in two finishes. The unique shape is both ergonomic and space saving. These 16mm knobs come in soft touch or hard plastic designs, with several indicator line orientations.

The bell or top-hat shaped knobs accept standard, "pan European" D-shape for 6mm shafts with a 4.5mm flat. Indicator lines or dots for pointing references come in various orientations - flat of shaft to 0, 90, 180 and 270 degrees. The indicator lines are available in blue or white. These exclusive design knobs are used in various medical, audio, defense, and industrial applications.

Simply press the knob into place over the encoder or switch and the knob's two internal pressure ridges keep it securely in place under a variety of operating conditions, yet they can be easily removed in necessary. The new range of knobs employ a 2-shot injection design, where one layer of molding covers a second layer. The soft touch versions utilize a firm rubberized material for a soft touch feel.

The bell-shaped knobs also have finger grooves for slip-proof turning action. This adds both ergonomic and aesthetic value. Also, the bottom of the knobs has an expanded diameter, which helps to conceal the panel-mounting nut.

Elma also offers collet knobs in various styles and sizes.

Elma's bell-shaped knobs are approximately $0.60/ea in volume and have a 2 week lead time. For more information on Elma's concentric switches, knobs, and custom design services, please contact Mark Thorsell at 510-656-5829 x228.
