NKK Switches Process Sealed Ultra-Miniature SMT Toggle G3T19AP

The G3T series consists of ultra-miniature, surface-mount toggle switches designed for low-voltage, low-current logic-level circuits. The switches feature a sealed construction with nitrile butadiene rubber sealing rings and polyphenylene sulfide housing, base, and actuator rated UL94V-0. They have gull-wing terminals, a 28° angle of throw, and a nominal operating force of 1.7N for maintained types. Contact resistance is maximum 80 milliohms, insulation resistance is minimum 500 megohms at 500V DC, and dielectric strength is 500V AC for one minute. The switches support reflow soldering, operate from -30°C to +85°C, and offer 50,000 mechanical and electrical operations minimum. The G3T19AP variant specifies an ON-OFF-(ON) circuit with upright mounting and gull-wing terminals, consistent with the series' 0.4VA maximum logic-level capacity and 0.6-gram weight.
