NKK Switches Process Sealed Subminiature Toggle A18KH-AA

The A Series is a line of process-sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. The switches feature a totally sealed body construction, gold-plated phosphor bronze contacts, and glass fiber reinforced polyamide housings. Terminal spacing is 0.100" x 0.100" (2.54mm x 2.54mm), conforming to standard PCB grid layouts. Electrical capacity is rated at 0.4VA maximum at 28V AC/DC, with contact resistance of 50 milliohms maximum and insulation resistance of 500 megohms minimum. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for others. Operating temperature ranges from -30°C to +85°C. The switches support wave soldering and include nonshorting contact timing with a 26° angle of throw. The A18KH-AA part number includes a flatted paddle toggle and vertical PC terminals with a snap-top cap, consistent with the A Series' configurable options.
