NKK Switches Process Sealed Subminiature Toggle A18EB

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, 50 milliohms maximum contact resistance, 500 megohms minimum insulation resistance, and 500V AC dielectric strength. They offer nonshorting contact timing, 26° angle of throw, and operate from -30°C to +85°C. Terminal spacing is 2.54mm x 2.54mm to conform to standard PCB grids. Mechanical life is 50,000 to 100,000 operations depending on circuit type, with 50,000 electrical life cycles minimum. Terminals are epoxy sealed or ultrasonically welded for contamination resistance. The series includes toggle options in antistatic polyamide and standard nickel-plated brass. No UL or CSA certifications are stated.
