The membrane switch circuitry is most often screen printed using conductive ink as silver, carbon or graphite. The circuitry can also incorporate different layers such as Polyester (silver flex), Polyimide (copper flex) and rigid PCB layer. Activation of a switch occurs when a printed shorting pad or metal dome makes contact with the bottom circuit layer thus, closing the circuit. Various application involves overlay membrane switch printing, membrane switch panel printing, flexible membrane switch printing, rigid membrane switch printing, silver flex membrane switch printing, copper flex membrane switch printing, PCB membrane switch printing can be accurately screen printed with our machines.
