Membrane Switch manufacturers: how to ensure that the graphics are clear and not wear? 

Most of the Membrane Switches use single-sided wool polycarbonate vinegar film, with screen printing method, graphics, symbols, color blocks, etc., printed on the smooth surface of polycarbonate bacterial film. They respectively play the role of modeling, decoration and reminder on the panel. Therefore, Membrane Switch manufacturers must take different technical measures in the production of wire mesh.

Membrane Switch screen printing is similar to general plastic film screen printing, and the film should be pre-treated before printing. The back of the panel, that is, the non-contact side of the panel, should be printed with text to ensure that the text on the electronic Membrane Switch is clear and non-abrasive. The text on the panel serves to indicate, convey instructions and explain the content. It requires smooth edges and complete strokes. Therefore, the film layer of the text screen must have a certain thickness, in order to ensure the thickness of the screen printing handwriting, in order to make the handwriting clear, durable, eye-catching and beautiful. Sensitive film of different thickness is suitable for different occasions.

Such as fine text should be slightly used film to improve the clarity of the writing; When the light-colored text or the three primary colors are used directly to print the text, the diaphragm should be thicker to make the tone more pure. In addition, the panel layer of the keypad membrane is usually provided with a transparent window, whose role is to provide a switching function to establish and reflect the working state of the machine, so that the operator or other personnel can manage the machine.

Generally speaking, as a key on the control panel, its sensitivity and service life will directly affect the application of the device. Therefore, for the production enterprise, on the basis of comprehensive consideration of the service life, price and aesthetics of the button, the final choice is made. Film buckle is actually the choice of many production enterprises after many comparisons, it meets the various requirements of modern buckle, such as feel better than silicone buckle; It can be used for a long time to prevent the key from being insensitive for a long time. In addition, the process is not complicated, so the cost is relatively low, which is also an important reason why the key is widely used in various electrical equipment. However, considering the large demand for switches by equipment manufacturers, it is recommended that equipment manufacturers choose regular switch manufacturers to ensure that the selected switch is a high-quality product.

Although the application of silicone keys is also more common, but the advantages of thin film keys are more, especially in terms of service life, it can be repeatedly pressed more than 1 million times, this alone is far more than the silicone key. Of course, how to choose the specific choice, as well as the choice of a company's products, but also need to compare the equipment manufacturers, after comprehensive consideration of the decision.
