NKK Switches Process Sealed Subminiature Toggle A18AV1

The A Series is a family of process-sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. All variants feature a totally sealed body, phosphor bronze contacts with gold plating, and glass fiber reinforced polyamide cases. They have a 26° angle of throw, nonshorting contact timing, and operate in a temperature range of -30°C to +85°C. Terminal spacing is 2.54 mm × 2.54 mm to conform to standard PCB grids. Electrical capacity is 0.4 VA maximum at 28 V AC/DC, with contact resistance ≤50 mΩ and insulation resistance ≥500 MΩ. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for other circuits. The A18AV1 variant is not explicitly listed, but the series includes vertical PCB terminals with V1 termination, as shown in dimensions for A12AV and A22AV models.
