NKK Switches Process Sealed Subminiature Toggle A24EV

The A Series is a family of sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. All variants feature a totally sealed body with epoxy or ultrasonically welded terminals to prevent contamination, a 26° angle of throw, nonshorting contact timing, and .100" x .100" (2.54mm x 2.54mm) terminal spacing conforming to standard PCB grids. The toggle is made of glass fiber reinforced polyamide or nickel-plated brass, with phosphor bronze contacts gold-plated for reliable operation. Electrical ratings include 0.4VA maximum at 28V AC/DC, 50 milliohms contact resistance, and 500 megohms insulation resistance. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, with 50,000 operations for other circuits. Operating temperature ranges from -30°C to +85°C. The A24EV variant is not explicitly listed, but the series supports multiple terminal options including vertical PC terminals (V) and paddle toggles, with antistatic toggle options available.
