NKK Switches Process Sealed Subminiature Toggle A18AP

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 operate from -30°C to +85°C and withstand 50G shock and 90-95% humidity at 40°C. The switches have a 26° angle of throw and nonshorting contact timing, with electrical life of 50,000 operations. Terminals have 0.100" x 0.100" (2.54mm x 2.54mm) spacing conforming to standard PCB grid layouts. The toggle mechanism is available in glass fiber reinforced polyamide (antistatic) or nickel-plated brass, with phosphor bronze contacts gold-plated for reliability.
