Claims

[Claims for Utility Model Registration] 1. Covering the entire upper surface of a PC board constituting an electric circuit with a flexible and water-resistant covering sheet, and wrapping the periphery of the sheet downward in a switch case. Alternatively, an operating switch for a rear view mirror is characterized in that the peripheral edge of the sheet is inserted into a recess provided inside the side wall of the case, thereby making the PC board and the contacts watertight. 2. The operation switch for a rearview mirror according to claim 1, which is a utility model, in which a bulge having a chevron-shaped cross section is formed on the surface of the covering sheet, and a ventilation hole communicating with the bulge is bored in the PC board. 3 The sheet covering the surface of the switch push button or operation knob is extended to form a bellows-like linking part,
An operation switch for a rearview mirror according to claim 1, wherein the peripheral portion thereof is stretched into a flat plate shape and covered with a PC board.
