NKK Switches Process Sealed Subminiature Toggle A12KB1-BB

The A Series is a family of sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. They feature a totally sealed body, 26° angle of throw, and nonshorting contact timing. Terminals have 2.54mm x 2.54mm spacing for standard PCB layouts. Contact resistance is 50 milliohms maximum, insulation resistance 500 megohms minimum at 500V DC, and dielectric strength is 500V AC between contacts and to case. 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 minimum. Operating temperature range is -30°C to +85°C. Contacts are phosphor bronze with gold plating, toggles are glass fiber reinforced polyamide or nickel-plated brass. The part number A12KB1-BB is not listed, but the series includes snap-top caps and vertical PC terminals as shown in ordering examples.
