NKK Switches Process Sealed Subminiature Toggle A18AB

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 totally sealed body to prevent contamination and support automated soldering and cleaning. They have a 26° angle of throw, nonshorting contact timing, and terminals spaced at 0.100" × 0.100" (2.54mm × 2.54mm) to conform to standard PCB grids. Electrical capacity is 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; electrical life is 50,000 operations minimum. Operating temperature ranges from -30°C to +85°C. The case and toggle housing are made of glass fiber reinforced polyamide, with phosphor bronze contacts plated in gold. The series includes vertical, right-angle, and straight terminal options with optional antistatic toggles and indicator caps.
