Title (EN) MEMBER FOR PUSH-BUTTON SWITCH AND METHOD OF MANUFACTURING THE SAME
(FR) COMPOSANT DE COMMUTATEUR A BOUTON-POUSSOIR ET SON PROCEDE DE FABRICATION
(JA) 押釦スイッチ用部材およびその製造方法
Abstract: front page image
(EN)A member for a push-button switch manufacturable at low cost and with high yielding and having key top members positioned close to each other through a distance of 1.5 mm or shorter and a method of manufacturing the member for the push-button switch. The member (1) for the push-button switch comprises a plurality of key top members (2) having resin key top cores (21) and thermoplastic films (22) covering the key top cores (21) other than the lower surfaces thereof. The key top members (2) are so formed that an interval between at least one set of adjacent key top members (2) among the key top members (2) is 1.5 mm or shorter. In the key top members (2) adjacent to each other through a distance of 1.5 mm or shorter, the maximum thickness (t0) of the thermoplastic films (22) covering the key top cores (21) comes within the range of 75 to 350 μ, and the ratio (t1/t0) of the minimum thickness (t1) of the thermoplastic films (22) covering the key top cores (21) to the maximum thickness (t0) comes within the range of 0.4 to 0.9.
(FR)L’invention concerne un composant de commutateur à bouton-poussoir pouvant être fabriqué à bas coût et en grande série, et comprenant des éléments supérieurs principaux disposés les uns près des autres à une distance maximale de 1,5 mm, et un procédé de fabrication dudit composant. Le composant (1) destiné à un commutateur à bouton-poussoir comprend une pluralité d’éléments supérieurs principaux (2) dotés de noyaux de résine (21) et de films thermoplastiques (22) recouvrant les noyaux (21), à l’exception de leurs surfaces inférieures. Les éléments supérieurs principaux (2) sont disposés de sorte qu’un intervalle maximal de 1,5 mm sépare au moins un ensemble d’éléments adjacents (2) parmi eux (2). Les éléments (2) adjacents à une distance maximale de 1,5 mm présentent une épaisseur maximale (t0) des films thermoplastiques (22) recouvrant les noyaux (21) comprise entre 75 et 350 µ, et un rapport (t1/t0) de l’épaisseur minimale (t1) des films (22) recouvrant les noyaux (21) à l’épaisseur maximale (t0) compris entre 0,4 et 0,9.
(JA) 低コストで歩留まりの良い、キートップ部材同士の間隔が1.5ミリメートル以下に密接している押釦スイッチ用部材およびその製造方法を提供する。  樹脂製のキートップコア21と該キートップコア21をその下面を除いて被覆する熱可塑性フィルム22とを備えるキートップ部材2を複数有する押釦スイッチ用部材1であって、キートップ部材2の内、少なくとも1組の隣り合うキートップ部材2の間隔が1.5ミリメートル以下で、その間隔が1.5ミリメートル以下の隣り合うキートップ部材2において、キートップコア21を被覆している熱可塑性フィルム22の最大厚み(t0)が75ミクロン以上350ミクロン以下の範囲にあって、最大厚み(t0)とキートップコア21を被覆している熱可塑性フィルム22の最小厚み(t1)との比(t1/t0)が0.4以上0.9以下の範囲である押釦スイッチ用部材1としている。
