Poly Dome Tactile Membrane Switch

TianTai Electronics is a leading China poly dome tactile membrane switch manufacturer. Poly Dome Tactile Membrane Switch has no moving parts like a metal dome.  Since the button is formed into the interface, it offers a long life that is easy to clean and durable against the constant use of cleaners.

The top layer of a poly dome tactile membrane switch is polyester or PET.  This control layer gets formed or embossed into a round button shape. Right under the PET is a little dollop of conductive ink, usually carbon or silver.  This can be referred to as the top part of the printed circuit.

Many of the poly dome tactile membrane switch also have another layer of PET to create a space between the layers of conductive ink. The bottom layer of a membrane switch has conductive ink traces that create the printed circuit’s bottom layer.
