NKK Switches | WR13AS

The WR Series of environmentally sealed rockers switches. Single unit construction of the flange and outer housing gives added protection from environmental elements. 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 UL94 V-0 flammability standard and provides high arc and tracking resistance. Addition of new .250” quick connect terminal option. Now available with solder lug, screw, quick connect, and wire lead terminations.
