Reference of Membrane Switches

We one of the biggest manufacturers of Printed Flexible circuit in China.

One kind of Printed Flexible circuits is membrane switch which include many layers circuits.

Most of the membrane switch keypads that we made are waterproof.

Membrane Touch Switch means many keys or buttons on it, so we call it touch switch or push buttons switch.

Below is some specifications of membranes.
1. Material (PE, PC)
2. Adhesive 3M
3 Nicomatic Connector
A. Material: RoHS compliant material, for example, Autotype, 3M, Nicomatic.
B. Dimension: According to customer 's drawing or design, OEM design.
C. Color: Pantone and Ral color match system.
D. Constrution: Various types to meet customer 's demand.
