Abstract
Abstract Two like L-shaped elements mate together to form an insertable switch housing having a number of spaced grooves in opposed end walls for accommodating different types of switches and have opposed pairs of cantilevered L-shaped legs serrated at the top that may be urged inward as the housing is inserted through an opening in a chassis and then snap out to coact with an outside lip of the hosing and sandwich a portion of the chassis plate adjacent the edge of the slot through which the switch is inserted. A feature of the invention is that a number of switches may be inserted side by side in a common slot with a generally Zshaped adapter between switches arranged to coact with respective generally L-shaped members so that two of the L-shaped members and one less than the total number of side-by-side switches to be accommodated form the housing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
An insertable housing comprising, means defining a wall formed with a bezel and a cantilevered ear having a free end adjacent to the bezel for coacting therewith to snugly engage a portion of a chassis plate, said ear being resiliently urGable toward said wall for passing through a chassis opening and then moving away from said wall to snugly engage the inside of the chassis plate, said housing comprising an element of generally L-shaped cross section having a long end wall perpendicular to a side wall.
Claim 2
Dependent Claim
86 words
An insertable housing comprising, means defining a wall formed with a bezel and a cantilevered ear having a free end adjacent to the bezel for coacting therewith to snugly engage a portion of a chassis plate, said ear being resiliently urGable toward said wall for passing through a chassis opening and then moving away from said wall to snugly engage the inside of the chassis plate, said housing comprising an element of generally L-shaped cross section having a long end wall perpendicular to a side wall.

An insertable housing in accordance with claim 5 and further comprising a short end wall opposite said long end wall formed with parallel grooves therein for accommodating electrical switches at different depths inside said chassis plate.
Claim 8
Dependent Claim
40 words
An insertable housing in accordance with claim 4 and further comprising a spacer element formed with a side wall and at least long end walls separated by the latter side wall and orthogonal thereto for mating engagement with said elements.
Claim 9
Dependent Claim
46 words
An insertable housing in accordance with claim 7 and further comprising a short end wall opposite each of said long end walls with each of said short and long end walls formed with parallel grooves for accommodating electrical switches at different depths inside said chassis plate.
Claim 10
Dependent Claim
36 words
An insertable housing in accordance with claim 4 wherein each corner of said L-shaped elements is formed with a half round boss adjacent to said bezel to facilitate insertion into a slot in said chassis plate.
