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.
