Abstract

It is a sealed touch switch and its process, which comprises the following steps: first to inject and mold a plastic case with its inner shape same to the outer shape of the touch switch, wherein, the inner size of the plastic case is little more than the outer size of the touch switch; to put the touch switch into the plastic case for another injection molding to seal the boundary of the touch switch surface with plastic case; to fill the lead wire hole with plastic liquid to seal it to add the stability and reliability of the switch.

Description

technical field [0001] The invention relates to a sealed touch switch and its manufacturing technology. Background technique [0002] The patent application with the application number 02106698.1 was filed by Isao Miyashita of Japan. The name is a touch switch, which discloses the structure and use of the touch switch. Its purpose is to increase the reliability of the switch. In the embodiment, it is mentioned to provide a A kind of waterproof seal, mainly for the spring piece, the flexible cover and gasket made of plastics surround the spring contact piece to achieve sealing. It is a partial seal and has the function of waterproof and moisture-proof. Under normal environmental conditions, use this Touch switches are perfectly fine. In poor environmental conditions, in the open air, wind, sun, rain, bumps, vibrations and other harsh environmental conditions, the requirements for waterproof, moisture-proof, and shock-proof are more stringent. Such as the touch switch of the...
