Environmentally Sealed Toggles Series WT Distinctive Characteristics Sealing at front and back panel meets IP67 and IP60 of IEC60529 Standards. (Contact factory for further details regarding operating environment.) Single unit construction of bushing and case gives added protection from environmental elements. Antijamming design protects contacts from damage due to excessive downward force on the toggle. Specially designed contact mechanism for breaking light contact welds. Minimal contact bounce achieved with designed interlocked switching mechanism. Heat resistant resin used for outer housing meets UL94V-0 flammability standard and provides high arc and tracking resistance. Actual Size Epoxy sealed base covered by outer case doubles protection from dust and water (not operable under water or oil).
