Environmentally Sealed Series WT Distinctive Characteristics Sealing for wire lead models meets IP67 of IEC6059 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,, and. Interlocked movable contact mechanism provides highly reliable switching by minimizing contact bounce over center contact. Heat resistant resin used for outer housing meets UL94V-0 flammability standard and provides high arc and tracking resistance. ctual Size Rockers Supplement ccessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons 5
