接合層20、40、及び60としては、任意の粘着剤又は接着剤を使用できる。本明細書において、粘着剤とは、常温で接着性を有し、軽い圧力で被着体に接着する層をいう。従って、粘着剤に貼着した被着体を剥離した場合にも、粘着剤は実用的な粘着力を保持する。一方、接着剤とは、物質の間に介在することによって物質を結合できる層をいう。従って、接着剤に貼着した被着体を剥離した場合には、接着剤は実用的な接着力を有さない。
フレーム30は、ガラス層70とスイッチ部80との間に介在することができる。図1の例では、フレーム30は、接合層20を介して、支持部10上に接合されている。図2は、フレームを例示する平面図である。図2に示すように、フレーム30は、固定部31と、固定部31に対して弾性支持部33で支持された可動部32とを有している。固定部31は開口部を有し、開口部内に可動部32が配置されている。固定部31と可動部32は、複数の弾性支持部33により可動自在に支持されている。なお、支持部10と接合されるのは固定部31のみであり、可動部32及び弾性支持部33は支持部10には接合されない。
樹脂層50は、ガラス層70とスイッチ部80との間に介在することができる。図1の例では、樹脂層50は、接合層40を介して、フレーム30の固定部31上に接合されている。樹脂層50は、可撓性を有する。樹脂層50の厚さは、可撓性の観点から50μm以上150μmであることが好ましい。樹脂層50の材料としては、例えば、ポリエチレンテレフタレート系樹脂やポリエチレンナフタレート系樹脂等のポリエステル系樹脂、ノルボルネン系樹脂等のシクロオレフィン系樹脂、ポリエーテルサルホン系樹脂、ポリカーボネート系樹脂、アクリル系樹脂、ポリオレフィン系樹脂、ポリイミド系樹脂、ポリアミド系樹脂、ポリイミドアミド系樹脂、ポリアリレート系樹脂、ポリサルホン系樹脂、ポリエーテルイミド系樹脂、ウレタン系樹脂等が挙げられる。
ガラス層70は、接合層60を介して樹脂層50上に積層されている。ガラス層70は、強化ガラスからなる。強化ガラスは、化学強化ガラスでも熱強化ガラスでもよいが、圧縮応力層を有する化学強化ガラスの方が熱強化ガラスよりも製造が容易である。ガラス層70は、圧縮応力が600MPa以上であることが好ましい。
スイッチ部80は、ガラス層70の裏面側に配置される。図1の例では、スイッチ部80は、支持部10の内側であり、かつ、フレーム30のガラス層70等とは反対側に配置されている。
実施例1では、図1に示す構造のスイッチ装置を作製した。ガラス層70として、圧縮応力が600MPaの化学強化ガラスを用い、厚さは200μmとした。また、樹脂層50の材料にはPETを用い、厚さは100μmとした。また、接合層60は接着剤とし、材料にはエポキシ樹脂を用い、厚さは1μmとした。
実施例2では、ガラス層70として、圧縮応力が600MPaの化学強化ガラスを用い、厚さは150μmとした。それ以外は実施例1と同様にしてスイッチ装置を作製した。
実施例2では、ガラス層70として、圧縮応力が600MPaの化学強化ガラスを用い、厚さは100μmとした。それ以外は実施例1と同様にしてスイッチ装置を作製した。
比較例1では、ガラス層70として、圧縮応力が600MPaの化学強化ガラスを用い、厚さは300μmとした。それ以外は実施例1と同様にしてスイッチ装置を作製した。
比較例2では、ガラス層70として、圧縮応力が600MPaの化学強化ガラスを用い、厚さは50μmとした。それ以外は実施例1と同様にしてスイッチ装置を作製した。
比較例3では、ガラス層70として、未強化ガラスを用い、厚さは200μmとした。それ以外は実施例1と同様にしてスイッチ装置を作製した。
比較例4では、ガラス層70として、未強化ガラスを用い、厚さは100μmとした。それ以外は実施例1と同様にしてスイッチ装置を作製した。
実施例1~3及び比較例1~4で作製したスイッチ装置について、ガラス層70を押したときにガラス層70が弾性変形してスイッチ部80を押せるか否かを確認した。具体的には、ガラス層70側から図3の矢印方向に荷重5Nの力で押したときにスイッチ部80が非導通から導通に切り替わるか否かを確認し、切り替わった場合を〇、切り替わらなかった場合を×とした。
実施例1~3及び比較例1~4で作製したスイッチ装置について、強度試験を行い、ガラス層70にクラックが入るか否かを目視で確認し、クラックが確認できなかった場合を〇、クラックが確認できた場合を×とした。強度試験は、JIS C4526-1:2021に規定されているスプリングハンマー試験に準拠して行った。なお、スプリングハンマー試験によりスイッチ装置に加えた力は、0.5Jである。
評価結果を図4に示す。図4の実施例1~3より、ガラス層70として圧縮応力が600MPaの化学強化ガラスを用い、かつ厚さを100μm~200μmとすることで、スイッチ部の導通と非導通を切り替えることができ、かつ十分な強度が得られることが確認できた。
