NKK Switches Process Sealed Subminiature Rocker A1RKH

The A Series is a family of sealed subminiature rocker switches designed for low-voltage, logic-level applications. It features a glass fiber reinforced polyamide housing, phosphor bronze contacts with gold plating, and gold-plated brass terminals. The switches have a 26° angle of throw, nonshorting contact timing, and a terminal spacing of 2.54mm x 2.54mm that conforms to standard PCB grid layouts. Electrical ratings include a maximum resistive load of 0.4VA at 28V AC/DC, contact resistance under 50 milliohms, and insulation resistance of at least 500 megohms. The mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, with an electrical life of 50,000 operations. Operating temperature ranges from -30°C to +85°C. The switches support surface-mount PCB terminating styles including right angle and vertical, with soldering compatible to wave and manual profiles. The A Series is not UL or CSA certified.
