Specially designed contact mechanism for breaking light welds. Minimal contact bounce achieved with specially designed interlocked switching mechanism. Heat resistant resin used for outer housing, inner case, and cover on wire lead models meets UL94V-0 flammability standard and provides high arc and tracking resistance. Available with solder lug, screw, quick connect, and wire lead terminations. Sealed Construction Meets IP60 & IP67 Standards Actual Size Solder lug, screw, and quick connect terminal models meet IP67 of IEC60529 Standards at front panel (dust tight and water protected for temporary immersion, patent pending). 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). Switch base is epoxy sealed and covered by an outer case for further protection from dust and water. (Switches cannot be operated under water.
