Customized design PET Membrane Switch with flat buttons glossy surface
What is a “Membrane Switch”?
A membrane switch is a printed electronic circuit that uses pressure to open and close a circuit. The membrane switch circuitry is most often screen printed using conductive inks, which are typically made of silver, carbon, and/or graphite.
Membrane Switch Technical Information
Graphic Overlay – Polyester is usually the material of choice due to its superior chemical resistance and flex life compared to polycarbonate. Pannam can either digitally print, screen-print, or employ a combination of both methods to ensure you get the right colors, textures and finishes your design requires.
Overlay Adhesive – This adhesive layer bonds the graphic overlay to the top circuit layer, and is typically an acrylic adhesive.
Top Circuit Layer – This is a 0.005″ – 0.007″ heat stabilized polyester printed with silver-filled electrically conductive inks and also dielectric inks.
Circuit Spacer – This layer separates the top circuit from the bottom circuit so the switch remains normally open until the keypad is pressed. The circuit spacer is a polyester spacer with adhesive on both sides.
Lower Circuit Layer – This is a 0.005″ – 0.007″ heat stabilized polyester printed with silver-filled electrically conductive inks and also dielectric inks. This layer terminates as a flexible tail that serves as the interconnect to controller PCBs or other electronics.
Rigid Support Layer – This optional layer can add structural integrity to the membrane switch assembly.
