NKK Switches Environmentally Sealed Pushbutton Nkk Switches WB12T-DA

The WB12T-DA is a single-pole, double-throw, momentary-action environmentally sealed pushbutton with screw terminal connections. It features a brass plunger with nickel plating, a fiberglass reinforced polyamide (UL94V-0) outer case, and silicone and nitrile rubber sealing rings for environmental protection. The switch meets IP67 standards behind the panel and has an electrical rating of 6A at 125V AC, 3A at 250V AC, or 6A at 30V DC. Contact resistance is 10 milliohms maximum, insulation resistance is 200 megohms minimum at 500V DC, and dielectric strength is 1,500V AC for one minute. Mechanical life is 30,000 operations minimum, and electrical life is 15,000 operations minimum. The operating temperature range is -30°C to +70°C. The actuator has a total travel of 0.110" (2.8mm), and the panel mounting requires 1.5 Nm torque.
