Patent ID: 7253368

Claim:
A pin anchoring structure for button switches, comprising: a switch body having a wiring space; and at least a first pin and a second pin located in the switch body, and a conductive connection member which is electrically connected to the first pin in normal conditions and connected to the second pin when subject to a force to generate a signal output; wherein the switch body has a holding aperture, the second pin having a pin section running through the holding aperture and a pressed coupling section located between the conductive connection member and the bottom of the switch body, the pressed coupling section and the corresponding bottom of the switch body being formed respectively in a bulged curve to facilitate installation of the second pin; wherein the pressed coupling section of the second pin is extended on another end to form a retaining section, the bottom of the switch body having a retaining hole corresponding to the retaining section; and wherein the curvature of the bulged curve of the pressed coupling section of the second pin is greater than that of the bottom.
