<p>PURPOSE:To thin the device itself and to curtail the manhour for assembling by providing projectingly an elastic material and welded piece for passing through a hole provided on a bottom plate part on a cover body, and welding and fixing the projecting part of this welded piece to the bottom plate part. CONSTITUTION:Welded pieces 5a, 5b projected to the lower part in a position between each hole 6 are provided on a cover body 5. Both the welded pieces 5a, 5b pass through a pass-hole 9d provided on an operating member 9 and a pass-hole 7a provided on a bottom plate part 7, and also, projecting end parts 5c, 5d of both these welded pieces 5a, 5b are welded in the lower side recessed part 7c provided on the bottom plate part 7. In this state, the cover body 5 and the bottom plate part 7 are fixed integrally, while interposing each membrane switch 8a - 8c and the operating member 9 between them. In such a way, the manhour for assembling can be curtailed and the thickness can be decreased.</p> |
