What it is and how to create a touch switch

June 10 , 2022

Touch switches increase the usability of electronic devices. While providing additional functions, these specific components provide a unique experience. That's because it can better control compatible devices. Although not a development of new technology, touch switches are still very popular today.


We work hard to help you gain deeper insights. After reading this article, you will find that there are three types of touch switches today, understand their functions, working principles, and applications. Want to create one yourself? We also detailed the steps you can take to design a touch switch! So please keep reading to get more knowledge about this technology.

1. What is a touch switch?


Mechanical switches control the circuit by applying pressure, while touch switches are slightly different. The touch switch is a tactile sensor that provides users with more control over any compatible electronic device. Regulators need to apply more pressure to close the circuit and operate, while touch switches need to be pressed lightly. 


These work through the conductive properties of human beings. This is because the human body acts as a conductor of the touch switch, and it detects conductive elements to function. Therefore, when you tap it, the capacitance decreases, forcing the circuit to close.


The manufacturer or user can modify the function, appearance and even performance of the touch switch. For example, doing so allows them to change the brightness and color of LED lights based on the pressure level.

2. Tact switch application


The touch switch can be operated when installed on surface panels and displays (such as acrylic, plastic, and glass). This makes them very popular in daily installment applications in homes and offices.


In addition, the multi-purpose keyboard is composed of multiple touch switches organized in series on the panel. Therefore, users can better control different applications. In addition, the touch screen display contains an array of touch switches.

3. The working principle of the touch switch


The touch switch works best when force, pressure, or touch is applied. When this happens, the connection will open or close in response to magnetic, optical, electrical, or chemical/mechanical factors. In addition, sometimes the input/output function allows it to run. For example, the virtual keyboard uses touch switches. In fact, pressure applied to a specific key triggers a response, which is then output to the system.


In conclusion


In the long run, touch switches exhibit several characteristics. With its features, you can be confident in more control. The different types also define how they should be integrated into popular devices, such as smartphones. In most cases, when you lightly press the touch switch, the circuit closes, triggering a specific function. In contrast, mechanical switches require more pressure. Therefore, this difference makes the touch switch the most common switch on the market today.
