Switch Membrane/ Assy Touch

Membrane switches, witha simple structure, are created by printing a circuit and a pattern on PET film using a conductive ink.
A circuit printed with a conductive ink consists of two layers, and is divided into upper and lower circuits with spacers in between.
The principle is simple: pressing the button on the top graphic overlay layer (Exterior) connects the upper and lower circuits separated by spacers.
This simple method allows membrane switches to be designed and manufactured in an ultra-thin profile, offeringthe advantages of design freedom and low development costs. In fact, membrane switches are used widely in digital appliances (such as microwaves, washing machines, bidets, and remote controls), computer keyboards, office equipment, electronic scales, and telecommunications equipment.
There are two main types of membrane switches: Standard and Embossed.

This layer corresponds to the front face of the membrane switch and is created using a method of thin screen printing on polyester (PET) or polycarbonate (PC) film.
It is based ona method to decorate switches on home appliances or machinery, serving as an attractive and functional alternative,
particularly when a three-dimensional look and feel is desired.

As mentioned earlier, the conductive circuit consists of two layers, with this circuit being the top layer.
Made of polyester, this layer is thin, flexible, and capable of moving at least one switch electrode or carrying a conductive shorting pad.

It is a 0.188t thickpolyester layer that separates the upper and lower circuits.This is also designed in the form of double-sided tape to secure the upper and lower circuits.
Holes are positioned precisely where the circuit contacts are located, allowing the contacts of the top and bottom plate circuits to make contact with each other under
external pressure.

As described earlier, the conductive circuit consists of two layers, with this circuit being the bottom layer.
Made of polyester, this layer is thin, flexible, and capable of moving at least one switch electrode or carrying a conductive shorting pad.

It isa layer of double-sided tape made of polyester. It is used to attach themembrane switch to appliances or mechanical products.
It comes with easily removable release paper that is peeled off before applying it to the product surface.

This layer corresponds to the front face of the membrane switch and is created using a method of thin screen printing on polyester (PET) or polycarbonate (PC) film.
A dome-like shape is formed by thermoforming on the top of this graphic overlay layer.

The embo spacer is inserted to prevent the rearside from adhering to the double-sided tape between the circuit and the graphic overlay layer when the switch is pressed.
It is made of the same polyester material as the spacer, and is 0.125t thick.
