NKK Switches Process Sealed Subminiature Toggle Nkk Switches A2RAV

The A Series is a family of sealed subminiature toggle switches for logic-level applications, with 2.54 mm × 2.54 mm terminal spacing and a totally sealed body for contamination resistance. The STC contact mechanism ensures stable, positive detent actuation. Contacts are gold-plated phosphor bronze, with a maximum rating of 0.4 VA at 28 V AC/DC. Contact resistance is 50 mΩ max, insulation resistance 500 MΩ min, and dielectric strength 500 V AC. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, 50,000 for others; electrical life is 50,000 operations. Operating temperature is -30°C to +85°C. The actuator throw is 26° with nonshorting timing. Wave soldering is limited to 270°C for 5 seconds. The switch is not UL or CSA certified. The A2RAV is a vertical, double-pole variant with ON-OFF-ON circuit, sharing all series specifications.
