Abstract
To solve the problem that a horizontal push-button switch for a small equipment like mobile phones is costly in tooling and does not have sufficient precision of positioning and fixing force due to a case made by molding and of a complicated shape with a step for reducing mounting height on the circuit board.The main body of the switch 11 is made a laminated structure of a substrate 12, a spacer 13, and an upper lid 14 with a metal side 15 surrounding this for enforcement. The upper lid is made of a molded part, however, is simple in shape and the substrate and the spacer are made of a simple plate part, and the step for the main body is made by forming only a spot facing of axb at the edge of the substrate and easy to manufacture. A cut-out is formed at the circuit board for housing the step and lower part of the switch body and a protrusion 15a is provided on the lower end of the metal side of the switch, whereby the switch is positioned by being inserted into the groove provided at the circuit board. Several enforcement pads for fitting are provided at the circuit board and the lower end of the metal side is soldered, improving fitting accuracy and fixing force.(C)2004,JPO.
