With the development of science and technology, in order to pursue the fashionable and beautiful appearance of new household appliances and consumer electronic products, the control panels of the products adopt an integrated design. The button symbols and patterns of the switch control part are injection molded into the panel through IMD technology.
Both the front and back sides of the panel are smooth and flat, and there is no need to make grooves or holes to assemble traditional mechanical switches. The areas without characters and patterns on the panel are all opaque, and the characters and patterns are made fully transparent or semi-transparent. When the device is turned off, the buttons' characters and patterns cannot be seen from the top of the panel because the bottom of the panel is dark. When the device is turned on, the LED light below the panel lights up, and the characters and patterns on the panel are displayed.
This kind of key switch will trigger the relevant button function as long as the finger touches the button area. In order to realize this function, an ultra-thin capacitive touch sensing control switch flexible circuit board needs to be attached to the back of the panel.
The material of capacitive touch sensor control switch flexible circuit board is generally PET or diffusion film, printed with low-resistance conductive silver wire and polymer transparent conductive oil, and then printed with 3M glue or directly made with 3M double-sided tape. The capacitive touch sensing control switch flexible circuit board can be directly attached to the back of the panel, with simple operation and comprehensive functions.
Capacitive touch sensor control switch flexible circuit board made of transparent PET printing. Low-resistance conductive silver wires can be clearly seen on the circuit board, and polymer conductive oil is printed inside the silver coils. When your finger approaches the sensing area of the button, the switch function of the button is triggered.
The capacitive touch sensor control switch flexible circuit board made of transparent PET printing has 3M double-sided tape on the back, which facilitates the capacitive touch sensor control switch flexible circuit board to be directly assembled behind the control panel of the device.
The capacitive touch sensor control switch flexible circuit board is made of high-transmittance white diffusion film imported from Japan. The button area of the circuit board can evenly transmit light, and the low-resistance conductive silver wire makes the button touch sensor more sensitive, and shielding is added between the wires to prevent interference.
Each button on the capacitive touch sensor control switch flexible circuit board has an exclusive conductive silver wire, which transmits the signal to the receiving IC on the motherboard PCB to realize the touch switch function.
Because the capacitive touch sensor control switch flexible circuit board is made of light and thin materials, it does not take up space and does not require direct contact with the outside world when used. It can be dustproof and waterproof. Capacitive touch sensor control switch flexible circuit board has clear buttons, sensitive response, much lower price than touch screen, and has the same functions and convenience as touch screen. It has replaced traditional mechanical switches in large numbers.
Capacitive touch sensing control switch flexible circuit boards have been widely used in the field of switch control of various types of equipment such as intelligent electronic measuring instruments, medical instruments, computer controls, CNC machine tools, electronic scales, postal and telecommunications, household appliances, and electronic game consoles.
