15 Amp ~ 250 Volts DC ~ 440 Volts AC Double Pole / Single Throw Design Laminated Yoke ~ Wooden Handle ~ Slate Base The black slate base is fully intact, and shows only very minor edge wear at its beveled top edge, which is typical for its age. The underside of the base shows original potting material in place, which appears to be an aged, dark amber, semi-gloss filler material. There are two original, double-stepped through-holes for surface or lab mounting, located in the base body. Mechanically connected to the base topside are two solid copper female blade receivers, each original, fully intact and operational. Each blade receiver is mounted from the base’s underside by individual through-hole machine screw threads. Further, each blade receiver has what appears to be an original, top-mounted, copper, wire hold down screw with captive washer for attaching circuit wiring. Also mechanically connected to the base’s topside, are two, solid copper blade hinge/pivot blocks. Each pivot block carries its original hardware consisting of a small machine bolt, washer, and nut in place, and is fully operational. Each pivot block is further mounted from the base’s underside by individual through-hole machine screw threads. One pivot block has its' original, top-mounted, copper wire hold down screw with captive washer, for attaching circuit wiring. The remaining pivot block exhibits a partial screw thread only, which has not been altered or corrected. The black laminated double blade yoke, and the black wooden handle are each fully intact with no cracks, chips, or splits. Both the yoke and the handle fasteners appear original, snug-fitting, and functional.
