Flexible Membrane Keyboard/ Switches

A membrane Keyboard has two screen printed polyester films with conductive ink to form the circuit layer of the Keyboard. Between the two circuits, a die-cut spacer at contact points is placed. To complete the circuit a touch of finger on the die-cut holes allows to close the contact. Upon release, the circuit is broken. User can specify the specific key contacts through a Graphic overlay. For interfacing with the customer’s electronics, the panel back is laminated with an adhesive for mounting on a backer or enclosure which can be terminated to a malefemale clincher connector.
