Question:

What are the advantages of membrane switch series?

Answer:

Membrane switch has many advantages: It is resistant to water, dust, oil and harmful gas erosion, and is stable and reliable in properties. It has small volume, long service life, and convenient installation. Its panel can be washed without damage of characters on it. It also has rich color and elegant appearance. Your product will obtain more distinct features of the time by using the membrane switch. Main types of the membrane switch: With rigid or flexible printed circuit board as substrate, the membrane switch panel is made with plastic (polycarbonate, polyester, etc.) faceplate with colored decorative patterns printed on it. It is installed with keys with hand feeling or not. It is a kind of electronic component integrating switch function with decorative function, and also has a new human-machine interface. Its switching circuit and connection mode of the complete appliance can be finished by welding or plug-in.
Advantages of membrane switch series: Good hand feeling of keyboard, uniform strength, and high precision stroke; You can hear crisp sound during operation, and know clearly about the operational circumstances so as to avoid repetitive operation due to the buffer time of certain equipment; Use temperature can be up to -20~ 80℃. .
1. Folding membrane switch. It is usually printed the pattern symmetrical in the upper and lower circuit on the same side of the membrane, and folded along the graphical symmetry axis to form the upper and lower circuit which constitutes corresponding contact of a set of switches keyboard under the action of the spacer layer. This is called folding circuit. 2. Double-plate membrane switch. It is printed two contacts of a set of switches, and wires and leads of the switch contact on two membranes respectively, constituting the upper and lower circuit of the switch. The double-chip circuit, for its lead is not folded, overcomes some of the defect of the folding circuit.
