NKK Switches Process Sealed Subminiature Toggle A22KH-BB

The A series is a family of process-sealed subminiature toggle switches designed for low-voltage, low-current logic-level applications. The switches feature a total sealed body construction, gold-plated phosphor bronze contacts, and glass fiber reinforced polyamide housing. They provide a 26° angle of throw, nonshorting contact timing, and a terminal spacing of 2.54 mm x 2.54 mm matching standard PCB grids. The operating temperature range is -30°C to +85°C, with a mechanical life of up to 100,000 operations for On-None-On and On-Off-On circuits, and an electrical life of 50,000 operations. Contact resistance is 50 milliohms maximum, and insulation resistance is 500 megohms minimum at 500 V DC. Soldering is compatible with wave and manual methods. The A22KH-BB variant includes a short paddle toggle and vertical PC terminals with a bracket, consistent with the series' dimensional and functional specifications.
