NKK Switches Process Sealed Subminiature Rocker A28KB-CE

The A Series is a family of process-sealed subminiature rocker switches for low-voltage, low-current logic-level applications. They feature a totally sealed body, 26° angle of throw, and nonshorting contact timing. Terminal spacing is 2.54 mm x 2.54 mm. Contact resistance is 50 milliohms maximum, insulation resistance 500 megohms minimum at 500V DC, and dielectric strength is 500V AC for one minute. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, 50,000 for others. Electrical life is 50,000 operations. Nominal operating force is 2.73 N for momentary and 1.84 N for maintained types. The actuator is nickel-plated brass, the case is glass fiber reinforced polyamide, terminals are gold-plated brass. Operating temperature range is -30°C to +85°C. Humidity resistance is 90-95% for 240 hours at 40°C. No UL or CSA certifications are listed.
