Elma knobs in bell shape, top-hat designs

Elma Electronic Inc., a designer and manufacturer of rotary components and electronic packaging products, has expanded its electronics knob line with the release of its new "bell-" or "top-hat" shaped knobs in two finishes.

According to the company, the unique shape is both ergonomic and space saving. The 16mm knobs come in soft touch or hard plastic designs, and accept standard "pan European" D-shape for 6mm shafts with a 4.5mm flat.

Users just have to 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. However, the knobs can be easily removed if necessary. The products employ a 2-shot injection design, where one layer of molding covers a second layer.

Available in blue or white, the product's indicator lines or dots for pointing references come in various orientations: flat of shaft to 0-, 90-, 180-, and 270°.
