AMI DODUCO Introduces Cadmium-free Contact Materials for House-wiring Switches.

PFORZHEIM, Germany -- AMI DODUCO, a Technitrol (NYSE:TNL) Company, presented favorable test results on several cadmium-free contact material alternatives for house-wiring switches at the 10th International Conference on Switching Arc Phenomena in Lodz, Poland.

Traditionally, house-wiring switches have had to withstand only small loads required by simple tungsten light bulbs. Due to today's high-performance halogen and fluorescent lamps with start-up peaks of over 200 amps, loads have become much more demanding, calling for cadmium-bearing materials such as silver cadmium oxide. The continued use of silver cadmium oxide materials is a concern because it is unclear when the European Union's Restriction of Hazardous Substances Directive will prohibit the use of cadmium in house-wiring switches, as is already the case with industrial switches.

Tests confirmed that AMI DODUCO's silver zinc oxide 92/8 with the additive silver tungstate (Ag2WO4) demonstrates the service longevity, weld resistance and minimal heat attenuation required for high-load household switches. In addition, high workability makes this a very practical material.

"We carried out comprehensive material tests with silver nickel, silver tin oxide and silver zinc oxide on a specially developed, practice-oriented test rig to develop the required test data," AMI DODUCO's Oliver Lutz told conferees. "As a result, our patented silver zinc oxide material with silver tungstate was approved for general use."
