An improved viewing window construction for an electrical disconnect switch 10. The improved construction of the viewing window 70 permits easier installation of the viewing window 70 while at the same time reducing the complexity of the switch cover manufacturing process, eliminating the need for a window retainer 46 and increasing the resistance to the ingress of water when subjected to a stream of water under pressure.
