Description:
What is the difference between membrane switch and keypad switch<br/><br/>Membrane switches and keypad switches differ significantly in several ways:<br/><br/>Firstly, from the perspective of structure and working principle, the membrane switch is composed of four parts: panel, upper circuit, isolation layer and lower circuit.When the membrane switch is pressed, the contact of the upper circuit will deform downward and contact with the electrode plate of the lower circuit to conduct, so as to realize the connection of the circuit. The keypad switch is usually composed of normally open contact and normally closed contact, when the key of the switch is pressed, the normally closed contact will be disconnected, and the normally open contact will be closed, so as to realize the circuit is connected.<br/><br/>Secondly, membrane switches are more integrated and independent. It is not just a simple switch, but the panel, switch and conductive circuit integrated together, can independently constitute a complete control system, providing users with a complete switching solution. The keypad switch usually needs to be combined with other components (such as PCB circuit boards) to form a complete switch control system.<br/><br/>In addition, the membrane switch also performs well in terms of life, tightness, decoration and economy.The life of the membrane switch can reach more than a million times, while the life of the traditional keypad switch is relatively short.At the same time, the membrane switch is the sealing structure of the whole machine, which has the ability of fire prevention, dust proof, explosion proof and harmful gas erosion, especially suitable for harsh environments. Its appearance is in a diffuse matte tone with a soft surface that helps protect the vision.In production, membrane switch is designed according to the finalized one, than the traditional production process is more simplified and the economic of the switch.<br/><br/>To sum up, membrane switch and keypad switch have obvious differences in structure, working principle, integration, life, sealing, decoration and economy. The choice of which switch to use needs to be balanced according to specific application scenarios and requirements.
