NKK Switches Environmentally Sealed Rocker Nkk Switches WR18AT/CUL

The Environmentally Sealed Rocker Switch (part number 10X9946) from Newark, An Avnet Company, is designed for robust applications requiring protection against environmental elements. It supports a power level of 15A at 125/250V AC or 15A at 30V DC, making it suitable for various electrical loads. The switch features a contact resistance of 10 milliohms maximum for solder lug, screw, and quick connect terminal models, and 30 milliohms maximum for wire lead terminal models. The insulation resistance is rated at a minimum of 200 megohms at 500V DC, with a dielectric strength of 1,250V AC minimum between contacts and 3,750V AC minimum between contacts and case. Mechanical life is rated for a minimum of 30,000 operations, while electrical life varies from 10,000 to 15,000 operations depending on the circuit model. Constructed with materials that meet UL94V-0 flammability standards, the switch is available in various termination types including solder lug, screw, quick connect, and wire lead. It is rated IP67 for front panel sealing, ensuring dust tightness and water protection during temporary immersion, while behind panel sealing varies by model. The operating temperature range is from -25°C to +85°C, accommodating a wide range of environmental conditions. This switch is suitable for applications where reliability and environmental protection are critical.
