Switches Perform in Harsh Environments
Meeting IP67, IEC60529, UL94V-0, UL 1015, and CSA TEW 105 standards, NKK Switches’ WT, WR, and WB Series environmentally-sealed switches operate in refrigeration equipment, AC motor control, monitoring equipment, biomedical instrumentation, and boating applications. The single- and double-pole WT toggles exhibit current ratings of 10 A at 125 VAC or 30 VDC and 6 A at 250 VAC, min. mechanical life of 30,000 operations, min. electrical life of 15,000 operations, and bushings with an anti-jamming design and an inner and outer sealing ring. The single-pole WR rockers present a current rating of 15 A at 125 VAC, 250 VAC, and 30 VDC, as well as a min. mechanical life of 30,000 operations and a min. electrical life of 10,000 operations. The single-pole WB pushbuttons offer current ratings at 6 A at 125 VAC and 30 VDC and 3 A at 250 VAC, min. mechanical life of 30,000 operations, and min. electrical life of 15,000 operations.
