The A Series is a family of process-sealed subminiature rocker switches designed for low-voltage, low-current logic-level applications. The switches feature a totally sealed body, gold-plated phosphor bronze contacts, and glass fiber reinforced polyamide housing. They have a contact resistance of 50 milliohms maximum, insulation resistance of 500 megohms minimum, and dielectric strength of 500V AC for one minute. The operating range is 0.4VA maximum at 28V AC/DC, with a mechanical life of 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for others. Electrical life is 50,000 operations minimum. Nominal operating force is 2.73N for momentary and 1.84N for maintained types. The angle of throw is 26°, and terminals have a 2.54mm x 2.54mm spacing. Operating temperature ranges from -30°C to +85°C. The switches support wave and manual soldering. No UL or CSA certification is provided.
