Abstract The anti-glare covering for illuminate switch or indicator of the invention is formed of a covering member shaped from a transparent synthetic resin and a microlouver-type anti-glare sheet melt-bonded to the lower surface of the covering member. This structure is different from conventional anti-glare coverings for illuminate switch or indicator in which the covering member has a top opening and the microlouver-type anti-glare sheet covers the opening. Thus, the anti-glare covering of the invention is provided with improved visiblity and rigidity and is easy to maintain beautiful appearance. The visibility of the illuminate switch or indicator is further improved by providing a thin light-transmitting metallizing layer on the upper surface of the covering member at the top portion.
An anti-glare covering for an illuminate switch or indicator which comprises: (a) a covering member having a flat portion and two spaced-apart leg portions extending vertically from a surface of said flat portion; and (b) an anti-glare microlouver sheet integrally melt-bonded to said covering member between said leg portions.

An anti-glare covering for an illuminate switch or indicator which comprises: (a) a covering member having a flat portion and two spaced-apart leg portions extending vertically from a surface of said flat portion; and (b) an anti-glare microlouver sheet integrally melt-bonded to said covering member between said leg portions.
Claim 3
Dependent Claim
22 words
The covering of claim 1 wherein said microlouver sheet is bonded to said surface of said covering member between said leg portions.
Claim 4
Dependent Claim
24 words
The covering member of claim 1 having a recess in said surface between said leg portions, said microlouver sheet being bonded within said recess.
Claim 5
Dependent Claim
30 words
The covering member of claim 1 which further comprises a thin light-transmitting metallizing layer on a surface of the covering member opposite the surface from which the leg portions extend.
Claim 6
Dependent Claim
30 words
