Definitions

  • an object of the invention is to provide for inspection of the interior contacts and parts after they are assembled in a switch casing, by provision of removable casing walls.
  • a related object is to provide cooperating base structure and flexible walls shaped so that the Walls may be quickly and easily snapped into place, and may be readily removed.
  • FIG. 1 is a plan view of a switch casing embodying the invention
  • Fig. 2 is a side view of the switch casing
  • Fig. 3 is an end View of the switch casing partly broken away.
  • the casing comprises an insulation base 8
  • the casing illustrated is particularly adapted for use with a switch mechanism and contacts as illustrated and described in my above identified copendingapplication because in that form, as in certain other switches it is impossible otherwise to inspect the contacts after assembly.
  • the invention is not limited to use with that particular switch and contact structure.
  • the casing or base 8! there shown has its side walls open with a semi-circular upward extension 82 from the bottom edge of the opening 83 to provide additional rigidity to the casing.
  • the casing or base 8! there shown has its side walls open with a semi-circular upward extension 82 from the bottom edge of the opening 83 to provide additional rigidity to the casing.
  • the bottom edges of the opening are grooves 84 to receive the feet 86 of a thin wall plate of sheet insulation 80 whose outline is substantially the same as that of the opening 83.
  • a metal switch cover plate 85 may be bent over to provide flanges 88 divided at their center by tongue 98 bent parallel to the flanges but spaced therefrom a distance slightly greater than, but approximating the thickness of the wall plate 80. Because of slight resiliency of the wall plate, it is possible, after inserting feet 86 in grooves 84, to snap the upper edge between the flange 88 and the tongue 90, or vice versa.
  • grooves may be formed in the short side edges of the opening 83 and the plate flexed to enable insertion of the short edges of the plate therein.
  • the flanges 88 and tongues 98 and grooves 84 may be omitted, and the top and bottom edges of the plate 80 will abut the under side of the cover and the bottom edge of the opening 83, respectively.
  • the cover plate may be held in place by bolts or secured by arms 92 of the shape shown in Fig. 3, extending from the ends of the cover and bent down into channels in the casing walls.
  • a casing for an electric switch of the class wherein a switch operating spindle carries. contact operating member which conceals and prevents access to contacts beneath said member after the switch is assembled in the casing but wherein inspection and adjustment of the contacts are necessary after such assembling, said casing comprising a hollow insulating base having a side wall recessed from its top edge to a depth and width to permit inspection and adjustment of the switch contacts, means formed into the lower edge of said recess to receive the edge of a plate, a cover member extending over said base and secured thereon over the assembled switch in the base, a flexible insulating plate engaged and held by said cover member and said means formed in the lower recess edge, said plate being flexible so as to be flexed into engagement,
