Introduction to PCB Membrane Switch

Membrane switches are popular. One piece consists of a thin plastic or polymer film and a conductive circuit in it. Membrane switches can be divided into different types based on different designs. The addition of printed circuit board can make many functions come true.


Schematic design


In the schematic design, things such as the combination of the membrane switch and PCB, position of the buttons, and circuit connections are important. In addition, the number, size and location of membrane switches need to be determined based on actual application requirements.


For the technological process of the circuit, there are following steps.


Prepare materials


I mean the materials of membrane switches, printed circuit boards, electronic components, etc..


Install membrane switch


Place the membrane switch on the circuit board to ensure the position is accurate.


Circuit connection


Connect electronic components to membrane switches and printed circuit boards by welding or plugging.


Testing and debugging


Ensure that the circuit can work well through testing and debugging.


Elements and equipment


The required materials are membrane switches, printed circuit boards, electronic components, insulation materials, etc. The quantity and specifications are determined based on actual needs. The required equipment are welding tools, plugging tools, testing instruments, etc.




PCB membrane switches are widely used in electronic devices, such as mobile phones, tablets, calculators, remote controls, etc. In the field of smart homes, PCB membrane switches combined with various circuits are also used in products such as smart lights and smart speakers, bringing convenience and intelligence to people's lives.


Different types of membrane switches have their pros and cons. They need to be used according to actual needs. For example, touch switches have the advantages of beautiful appearance, high sensitivity, and long service life, but they have disadvantages such as high cost and sensitivity to environmental humidity. Mechanical switches have the advantages of low cost, high reliability, and long service life, but they have disadvantages such as unsightly appearance and large size.




With the continuous advancement of technology and the growing demand for applications, PCB membrane switches will be more applied and optimized.


For example, under the trend of intelligent development, more intelligent operation and control can be achieved by combining with technologies such as the Internet of Things and artificial intelligence. At the same time, with the popularization of the concept of green environmental protection, PCB membrane switch will also develop in a more environmentally friendly and sustainable direction.
