The new GN 422 is timeless, multifunctional, rugged and attractive. Developing handles with an electrical switching function allows complex functions to be miniaturized and yields a solution for safety-critical applications. In view of the required material characteristics, it was decided to use solid die-cast zinc. In addition to a high level of precision, the robust material satisfies the demands of tough applications. The handles also come with one or two buttons with integrated LED ring lights that shine red or green depending on the polarity.
