NKK Switches Process Sealed Subminiature Rocker A25K1B-EA

The A Series is a family of sealed subminiature rocker switches designed for low-voltage, low-current logic-level applications. Each switch features a totally sealed body to prevent contamination and support automated soldering and cleaning. Terminals have a 2.54mm x 2.54mm spacing compliant with standard PCB grids. Electrical capacity is 0.4VA maximum at 28V AC/DC, with contact resistance of 50 milliohms max and insulation resistance of 500 megohms min at 500V DC. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, 50,000 for others. Nominal operating force is 2.73N for momentary, 1.84N for maintained. The actuator is nickel-plated brass, the housing is glass fiber reinforced polyamide, and contacts are phosphor bronze with gold plating. Operating temperature ranges from -30°C to +85°C. The angle of throw is 26°, with nonshorting contact timing. The A Series has not been tested for UL or CSA certification.
