Abstract
A switch device includes (a) a switch arranged on a bottom of a recess, and (b) a waterproof sheet adhered at its outer edge to a wall defining the recess, at a certain height to entirely cover the recess therewith. The waterproof sheet has a first area greater than a cross-sectional area of the recess when the waterproof sheet is in its original planar form. A difference between the first area of the waterproof sheet and the cross-sectional area of the recess allows the switch to be actuated through the waterproof sheet, and disallows moisture to enter the recess through the waterproof sheet. The waterproof sheet is composed of transparent or semi-transparent resin, for instance. The waterproof sheet may be adhered at its outer edge to a summit or a bottom of the wall.
