    • The invention discloses a membrane switch circuit and a keyswitch using such membrane switch circuit. The keyswitch comprises a deformable member, which is disposed on the membrane switch circuit. The membrane switch circuit according to the invention comprises a membrane circuit, an adhering layer, and an insulating layer. The membrane circuit thereon comprises a switch. The adhering layer is formed on the membrane circuit and surrounds the switch. The adhering layer comprises at least one gap. The insulating layer is formed on the adhering layer. The insulating layer has a hole in which the switch is exposed. A bottom of the deformable member is adhered to the insulating layer. In particular, the at least one gap covered by the bottom of the deformable member is utilized as at least one vent.
    • 本发明公开了一种薄膜开关电路和使用这种薄膜开关电路的钥匙开关。 钥匙开关包括可变形构件,其设置在膜开关电路上。 根据本发明的膜开关电路包括膜电路,粘附层和绝缘层。 其上的膜电路包括开关。 粘附层形成在膜电路上并围绕开关。 粘合层包括至少一个间隙。 绝缘层形成在粘合层上。 绝缘层具有露出开关的孔。 可变形构件的底部粘附到绝缘层。 特别地,由可变形构件的底部覆盖的至少一个间隙用作至少一个排气口。
