Mounting Torque: 1.47Nm (13 lbin) Standards & Certifications Flammability Standards: UL94V-0 outer case Wiring Material Standards: UL AWM 1015 Recognized at Flammability VW-1 Temperature Range 20C ~ +105C Maximum Load 600V AWG 16. CSA TEW 105 Certified at T emperature Range 20C ~ +105C Maximum Load 600V A132 www.nkkswitches.com 04/01/19 Supplement Accessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons Rockers TogglesEnvironmentally Sealed Toggles Series WT A Distinctive Characteristics Sealing for wire lead models meets IP67 of IEC60529 Standards at front and back panel. Sealing for solder lug or screw lug models meets IP67 at front panel and IP60 at back panel. Single unit construction of bushing and case gives added protection from environmental elements. Epoxy sealed base covered by outer case doubles protection from dust and water (not operable under water or oil). Specially designed contact mechanism that breaks light contact welds for circuits 11, 12, 21 and 22. Interlocked movable contact mechanism provides highly reliable switching by minimizing contact bounce over center contact. Actual Size Heat resistant resin used for outer housing meets UL94V-0 flammability standard and provides high arc and tracking resistance. www.nkkswitches.com A133 Supplement Accessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons Rockers Toggles
