Description

Technical Field

[0001] The utility model relates to the technical field of waterproof structures, in particular to a waterproof structure of a waterproof luminous film circuit switch. Background Art

[0002] The waterproof luminous film requires a membrane switch during use. The membrane switch is a multi-layered key switch composed of a certain elastic insulating material layer. It integrates the functions of buttons, indicating elements, instrument panels, etc. Its film material can withstand a long life of more than one million times without deformation. These factors determine the durability of the membrane switch. Therefore, it is widely used in many fields. In order to ensure the normal use of the relevant structures inside the membrane switch, the membrane switch usually needs to be waterproofed.

[0003] Existing membrane switches are usually waterproofed by coating the circuit layer with a waterproof film to protect the circuit layer. However, during long-term use, water vapor may penetrate and easily affect the use of the internal membrane switch. Therefore, we propose a waterproof structure for a waterproof luminous membrane circuit switch. Utility Model Content
