Membrane Switches

Membrane switches primarily consist of three parts: the operating panel, the upper circuit layer, the isolation layer, and the lower circuit layer. The upper and lower circuit layers are printed with conductive silver paste and carbon ink on a non-conductive polyester film (PET), forming a multi-layer flat circuit panel composed of conductive and insulating materials with a certain degree of flexibility. It's worth mentioning that all our structures have undergone RoHS inspection and certification, ensuring the safety and environmental friendliness of our products.
We offer two common substrates for our membrane switches: PC (polycarbonate) and PET (polyethylene terephthalate), each with different characteristics for various applications in membrane switches. PC substrates can undergo various surface treatments, including glossy, matte, semi-matte, glossy-matte, and scratch-resistant glossy, making them suitable for diverse environments and requirements. PET substrates, on the other hand, are commonly used in membrane switches and can also be applied as coating or embossing materials, offering options for scratch-resistant glossy and scratch-resistant matte finishes.

Convex membrane switches typically consist of two main parts: PC (polycarbonate) engraving plates and PET (polyethylene terephthalate) engraving plates.
These two types of plates are usually combined to form a sturdy and durable button structure. The PC engraving plate provides the external appearance and structural support of the button, while the PET engraving plate is responsible for forming the touch surface of the button, combining stability and reliability.

Touch panel switches play a crucial role in modern technology and design fields, providing convenient and agile operation for various applications.

There are various types of single-color abrasion-resistant materials available for touch panels, including transparent and colored options.

Furthermore, touch panels use PMMA/PC composite materials to enhance their performance and durability. PC is a highly durable and impact-resistant material, and when combined with PMMA, it can increase the lifespan and reliability of the switch. The application scope of touch panels is extensive, including technological products, electronic door locks, household appliances like refrigerators, medical instruments, and mechanical operation panels, among others.

Membrane circuits are components consisting of a polyester film (PET) substrate with conductive ink such as carbon powder or silver paste printed on its surface. These circuits are primarily used in electronic devices, especially for connecting printed circuit boards (PCBs) to surface buttons.

Here are the main characteristics and applications of these membrane circuits:

Flexibility and Lightweight: The PET film substrate provides excellent flexibility and lightweight properties, allowing these membrane circuits to be applied to curved or bent surfaces of electronic devices while also contributing to overall weight reduction.

Conductive Ink: Conductive ink is printed on the surface of PET film to form conductive patterns used for connecting functions in electronic devices. These conductive inks exhibit good conductivity and adhesion, enabling reliable connections.

Reliability and Durability: Due to the use of PET film as the substrate, these membrane circuits possess excellent wear resistance and durability, maintaining stable performance over prolonged periods of use.

Wide Range of Applications: These membrane circuits are commonly found in various consumer electronics such as mobile phones, tablets, remote controls, etc., used for connecting PCBs and surface buttons to achieve button operation functions.

In summary, membrane circuits utilizing PET as the substrate and printed with conductive ink on the surface are common connecting circuit components. They feature flexibility, lightweightness, durability, and are widely applied in various consumer electronics.
