NKK Switches Process Sealed Subminiature Rocker A19K1H-EA

The A Series is a family of sealed subminiature rocker switches designed for low-voltage, low-current logic-level applications. The switches feature a totally sealed body to prevent contamination, enabling automated soldering and cleaning. They have a 26° angle of throw, nonshorting contact timing, and a terminal spacing of 2.54 mm x 2.54 mm conforming to standard PCB grids. Electrical capacity is 0.4VA maximum at 28V AC/DC, with a contact resistance of 50 milliohms maximum and insulation resistance of 500 megohms minimum at 500V DC. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and electrical life is 50,000 operations minimum. The operating temperature range is -30°C to +85°C. Actuators are nickel-plated brass, contacts are gold-plated phosphor bronze and brass, and the housing is glass fiber reinforced polyamide. No UL or CSA certifications are listed. The A19K1H-EA part number is not explicitly printed, but the series characteristics apply to all variants.
