The components feature a 12-mm diameter bushing for standard panel openings and a behind-panel dimension of 27 mm. Other features include a positive detent mechanism, dielectric strength of 1.5 kV between contacts and case, mechanical life of 30,000 operations minimum, and an electrical life of 10,000 operations minimum.
