NKK Switches Process Sealed Subminiature Rocker A13K1B1

The A Series is a family of sealed subminiature rocker switches designed for low-voltage, logic-level applications. All variants feature a glass fiber reinforced polyamide housing, phosphor bronze contacts with gold plating, and brass terminals with gold plating. The switches have a nominal operating force of 2.73N for momentary and 1.84N for maintained types, with a contact resistance maximum of 50 milliohms and insulation resistance minimum of 500 megohms at 500V DC. They support a maximum resistive load of 0.4VA at 28V AC/DC and operate reliably over a temperature range of -30°C to +85°C. The mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for other types, with an electrical life of 50,000 operations. Terminals are spaced at 0.100 inch (2.54mm) to match standard PCB grids. Right-angle and vertical terminal versions require PCB extension no greater than 0.051 inch (1.3mm) to ensure full rocker travel.
