The precautions for the design of membrane switch keypads

The membrane switch button is a kind of text mark, which is mainly used for identification and protection. It can be seen in household appliances such as washing machines, refrigerators, microwave ovens, etc. in our family, and it can also be used in various industrial products Discover the membrane switch panel.

Membrane switch panel is a commercial and industrial product that has been commercialized internationally in recent years. The membrane keypads panel integrates decoration and function, and can be applied to commercial marks and product labels. So what are the considerations for the design of thin film panels?

Membrane Switch Design Considerations

1. The metal dome of the embossed button of the membrane switch needs to be placed properly, and there can be no offset, which will affect the operation of the keyboard to the point of failure.

2. Color problem: The modulation ratio of ink is the main reason for serious color deviation, and the color requirements are too strict. The color range is too small. These are factors that are difficult to control in any industry. From the point of view of the control cost of the enterprise, to achieve a very small color range, the cost to be paid is very high, the cost of the product rises, and the price of the product will rise accordingly, which is also unacceptable to customers, so. The range in terms of color needs to be within a reasonable tolerance range.

3. For the embossing position of the keypad, it is necessary to make the mold to the appropriate position, otherwise it will affect the beauty of the button. It is best to use the 3M brand for the back glue. In addition to the choice of raw materials, the shape of the casing should also be confirmed. If the casing has grooves, you need to choose a good quality adhesive.

4.Control of external dimensions, usually the tolerance of external dimensions is in the range of 0.2/-0.2mm. If strict tolerances are required, more precise molds need to be made
