What is a Capacitive Touch Sensor Film Switch
Capacitive switches are a type of switch that use electrical capacitance to detect touch input. They work by detecting changes in electrical capacitance caused by the proximity of a finger or other conductive object. The switch senses these changes and triggers an electrical signal.
The key advantage of capacitive switches is their durability, reliability, and resistance to environmental factors such as moisture and dust. They also offer improved performance and response times, making them suitable for high-speed and high-precision applications.
Another advantage of capacitive switches is their customization. They can be designed to meet the specific needs of each application, from customizing the shape, size, surface design, and location of the switch elements to the electrical characteristics of the switch itself.

Dr Pan: Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.
Greg: Hello, Dr Pan. I am Greg. I came to here to learn about thin film capacitive touch sensor.
Dr Pan: Hello,Greg. Thin Film capacitive touch sensor is the simplified version of surface capacitive touch screen. It is less than 0.3 mm, as thin as a blade.
Let’s look at the structure. From top to bottom, electrode pattern and conductive coating are functional layers, the bottom layer PET is supporting layer.
There are four electrodes on the four corners for surface capacitive touch screen to detect the location of the touch, therefore there are at least 4 wires. Meanwhile, there is only one wire to detect the existence of the contact for the touch sensor. We can see that it is practically an induction switch.
Greg: Dr Pan, do you mean only one wire matters no matter how many wires it has ?
Dr Pan: Not really. It depends on how many active areas in the touch sensor. Normally, one touch
sensor only has one active area, therefore only one wire is needed.
Check this one and there are three active areas and it needs 3 wires. The other three wires are unnecessary and empty.
We only use the 6-wire FPC to meet the requirements of FPC connector.
Greg: Thank you, Dr Pan. Now I got it.
Dr Pan: Welcome to contact us if you have any question.
