The A Series is a family of sealed subminiature rocker switches designed for low-voltage, logic-level circuits. They feature a glass fiber reinforced polyamide housing, gold-plated phosphor bronze contacts, and gold-plated brass terminals. Contact resistance is 50 milliohms maximum, insulation resistance is 500 megohms minimum, and dielectric strength is 500V AC for one minute. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for others. Electrical life is 50,000 operations. Operating temperature ranges from -30°C to +85°C. Terminals are spaced at 2.54mm × 2.54mm to conform to standard PCB grids. The angle of throw is 26° with nonshorting contact timing. PCB extension must not exceed 1.3mm to avoid impeding rocker motion, except for double-pole right-angle variants. The switches are not UL or CSA certified.
