Indentation operation electronic device and push switch

Abstract

The invention relates to an indentation operation electronic device and a push switch. The project of the invention is to make soft soldering with simple flux management and capable of corresponding with thickness of a metal mask, as well as realizing a thin type and miniaturization of the product. The indentation operation electronic device of the invention is provided, on one end side, with an outer fixed terminal (7a) revealed toward a hinder side face (2c) of a shell (2), and is provided, on the other end side, with an earthing contact component (7) of a leading out terminal (7b) extractedtoward side faces (2b) on the left and the right from underneath (2a) side of the shell (2); the earthing contact component (7) is arranged on the shell (2) together with converted contact components(5, 6) through insertion molding; besides, a cover (10) formed by metal material and the outer fixed terminal (7a) of the earthing contact component (7) are pushed against and installed on the shell(2); the leading out terminal (7b) of the earthing contact component (7) is connected with and installed on an earthing circuit of a printed circuit board.

Description

Technical field [0001] The present invention relates to a push-in operation type electronic device and a push switch, and more particularly to a push-in operation type electronic device and a push switch suitable for surface mounting on printed circuit boards of various electronic equipment. Background technique [0002] Conventionally, various components have been known for push-in operation type electronic components such as push switches mounted by surface mounting on printed circuit boards of electronic equipment (for example, refer to Patent Document 1: JP 9-120742 A). [0003] In addition, it is necessary to prevent static electricity from the operator’s body from flowing into the electronic device’s circuit from the hand or finger through the operating part of the push switch for push-in operation electronic components used on the printed circuit board of electronic equipment, namely push switches. Countermeasures for protection in As a countermeasure, generally, a ground t...
