Material made of Membrane Switches

Membrane switch panels are usually made of PC and PET, and the surface effect is divided into frosted and glossy. membrane circuits are usually made of PET material.

The comprehensive index of special physical properties and chemical properties of PC material is very good. It can well adapt to printing ink layer and is also a material commonly used in membrane switch panel layer.The PC material is resistant to a temperature of 80 degrees ,PC material has two kinds of frosted surface and smooth surface. Choose the PC film of frosted material The membrane panel is used in electronic products, it will not be disturbed by light when operating the control system, and it can prevent the surface from being scratched. Choose glossy material Membrane switch is used in mechanical equipment, the color of glossy material is more vivid after printing, electronic equipment with LCD display area usually uses glossy material to display more clearly, and it has the effect of oil resistance when using the equipment.

PET material has better comprehensive indicators of special physical properties and chemical properties, and its toughness is stronger, so it can be used in membrnae panels and membrane circuits. But its price is more expensive than PC material. The PET material is resistant to a temperature of 160 degrees, so it is more suitable for keypad embossed membrane keypads. There are two kinds of PET materials: matte and glossy. PET matte materials are usually used in film panels (graphic overlay), and glossy materials are usually used in thin membrane circuits.

In addition to the PET/PC material, the membrane switch also has an adhesive layer. 3M brand adhesive is often used. The membrane switch is usually composed of 6 layers of materials, which are composed of a membrane panel layer, panel adhesive layer, upper circuit layer, spacer adhesive layer, lower circuit layer, and back adhesive layer.
