Basic introduction to thin film switch with touch switch
Membrane switch is a system with key function, indicator, instrument panel. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. The principle of the membrane switch is as follows: press the membrane switch, the contact of the upper circuit deforms downward, and the plate contact of the lower circuit is conductive. After the finger is loosened, the contact of the upper circuit bounces back, the circuit is disconnected, and the loop triggers a signal. Thin film switch has rigorous structure, beautiful appearance and good sealing performance. It has the characteristics of anti-moisture and long service time. Widely used in electronic communication, electronic measurement instruments, industrial control, medical equipment, automobile industry, intelligent toys, household appliances and other fields.
The first thing we're going to talk about is, what is a membrane switch?
What are the basic things we should know about membrane switches?
Membrane switch is also called light touch keyboard, using a combination of planar multi-layer whole sealing structure, is to button switches, panels, tags, symbols show and liner seal together the set of optical, mechanical and electrical integration of a new type of electronic components, electronic product appearance structure of fundamental change, it can replace the conventional discrete component key, more reliable task execution system.
Film switch has a good waterproof, dustproof, oil, harmful gas erosion, stable and reliable performance, light weight, small size, long time, convenient assembly, the panel can be washed and the character is not damaged, colorful, beautiful and generous advantages. Use the film switch to make your products more characteristic of The Times. Membrane switch panel is a kind of main types of membrane switch by rigid or flexible printed circuit board for the substrate, installed on the handle or no touch key, and to print color decorative plastic (polycarbonate (PC), polyester PET) film panel, composed of switch function and decorate function for the integration of electronic components, is a new type of man-machine dialogue interface. The connection between the switch circuit and the whole machine can be completed by welding or plug. This is a basic introduction from Baidu Encyclopedia, I believe you can have a deeper understanding of the membrane switch and cognition.
