The A Series is a family of sealed subminiature rocker switches designed for low-voltage, logic-level applications. All variants feature a 0.100-inch (2.54mm) terminal spacing, 26° angle of throw, and nonshorting contact timing. The housing is glass fiber reinforced polyamide, with phosphor bronze contacts gold-plated and nickel-plated brass actuators. Electrical ratings include 0.4VA maximum at 28V AC/DC, 50 milliohm contact resistance, and 500 megohm insulation resistance. Dielectric strength is 500V AC for one minute. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits; electrical life is 50,000 operations. Operating temperature ranges from -30°C to +85°C, with 90-95% humidity tolerance at 40°C. Wave soldering is recommended. Installation requires PCB extension beyond the housing to not exceed 1.3mm for right-angle and vertical terminal variants. The switches are not UL recognized or CSA certified.
