<p>PROBLEM TO BE SOLVED: To prevent hooking of the pressing portion of a push button and a switch element in the way of building in an exterior cover, while preventing peeling and damage of the switch element and a substrate reliably, and to provide a push button built-in structure capable of facilitating built-in and removal of the exterior cover.SOLUTION: A protrusion 17a protruding farther than a switch element 14 is provided in a case 17, and inclined planes 17b, 17c extending in the built-in direction of an external cover 13 are provided at both ends of the protrusion 17a, thus preventing the pressing portion 12b of a push button 12 from being hooked to the end face of the switch element 14, in the way of building in the external cover 13, while preventing peeling and damage of the switch element 14 and a circuit board 15 reliably. Furthermore, build-in and removal of the external cover 13 can be facilitated.</p> |
