WB15T-ED

Environmentally Sealed Pushbuttons Series WB Distinctive Characteristics Single unit construction of the bushing and case gives added protection from environmental elements. Specially designed contact mechanism for breaking light welds. Minimal contact bounce is achieved with specially designed interlocked switching mechanism. Outer housing of heat resistant resin meets UL 94V-0 flammability standard and provides high arc and tracking resistance. Solder lug and screw terminal models meet IP67 of IEC60529 Standards at front panel (dust tight and water protected for temporary immersion). Behind panel standard is IP60 (dust tight but not water protected). Wire lead models conform fully to IP67 of IEC60529 Standards at front and behind panel (dust tight and water protected for temporary immersion). These models are epoxy sealed at the switch base and covered by an outer case for further protection from dust and water (not operable under water).
