NKK Switches Process Sealed Subminiature Toggle A18KB1-BB

The A Series is a sealed subminiature toggle switch designed for low-voltage, low-current logic-level circuits. It features a subminiature footprint with .100" x .100" (2.54mm x 2.54mm) terminal spacing conforming to standard PCB grid patterns. The switch has a 26° angle of throw, nonshorting contact timing, and a mechanical life of 50,000 to 100,000 operations depending on circuit type. 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. The housing is made of glass fiber reinforced polyamide, with phosphor bronze contacts gold-plated for reliability. Operating temperature range is -30°C to +85°C. Terminal options include vertical, right angle, and straight configurations with or without brackets. The switch is rated for wave and manual soldering and is suitable for automated cleaning. It has not been tested for UL or CSA certification.
