A membrane switch consists of two polyester films screen printed with conductive ink to complete the circuit. A spacer in between two circuits which is die cut at contact points. The die-cut holes allow the touch of a finger to close the contact, completing the circuit. The circuit is broken when released. The panel posterior is laminated with an adhesive for mounting to a backer or enclosure and is terminated with a means for interfacing with the customer's electronics.
Membrane switch keypad inquiry kindly provide detailed specification for quotation.
