Abstract

A membrane keyboard structure and a conductive method thereof allows a first surrounding portion of a first flexible circuit layer to be deformed to pass through an through hole to be in direct contact and conduction with a second surrounding portion temporarily when it is pressed through the coordination of a first flexible sheet body, first flexible circuit layer configured on the first flexible sheet body, spacer layer positioned on one side of the first flexible sheet body adjacent to the first flexible circuit layer, second flexible sheet body configured on one side of the spacer away from the first flexible circuit layer and second flexible circuit layer configured on one side of the second flexible sheet body adjacent to the spacer layer. Whereby, the present invention can achieve the contact and conduction anywhere to make the use thereof easier and more convenient.

Dependent claims

A membrane keyboard structure, having at least one membrane circuit body, comprising:

at least one first flexible sheet body, having at least one first hollow portion;
at least one first flexible circuit layer, configured on said first flexible sheet body and having at least one first surrounding portion around said first hollow portion;
at least one spacer layer, configured on one side of said first flexible sheet body adjacent to said first flexible circuit layer, and said spacer layer having at least one through hole corresponding to said first surrounding portion;
at least one second flexible sheet body, configured on one side of said spacer layer away from said first flexible sheet body, and said second flexible sheet body having at least one second hollow portion corresponding said first hollow portion;
and
at least one second flexible circuit layer, configured on one side of said second flexible sheet body adjacent to said spacer layer, said second flexible circuit layer having at least one second surrounding portion around said second hollow portion, and said second surrounding portion corresponding to said first surrounding portion to facilitate selective contact.
