Focus on thin film switches!

You will find that the keys of many membrane switches are raised. This place is easy to be overlooked. Sometimes, we will call the customer after carefully reviewing the drawings provided by the customer: Hello, if the key area needs to be convex, it is not recommended to make it with sharp corners. Can it be made with rounded corners? Sharp corners are risky. What is a bump? Button bulge is used to press drum machine on the mask layer of the key body area convex. Button convex, according to the natural characteristics of the material and convex characteristics, there are strict temperature and pressure requirements. Back to the point: thin film panel on the button area convex operation, can better help the operator quickly determine the location of the button, so that the button feel better, but also make the product more design and three-dimensional sense. There are four advantages of button protruding: 1, improve the decorative effect of the appearance of the film panel 2, improve the operator's touch 3. Accurately specify the range of the bond body 4. Improve the identification speed How many convex styles are there? Provide a variety of convex style, mainly divided into 5 categories: round convex, pan convex, edge convex, button shape convex, plane without convex. If the customer marks the convex area in the drawing of the membrane switch panel, the default is to adopt the first convex mode (circular convex). If any other method is needed, it can be noted in the notes or drawings when placing an order. Convex height range is 0.3-0.8mm, default convex height is 0.5mm. Why do sharp corners have a risk? Note to customers: when designing the raised area of the membrane switch panel, please design it as an arc Angle. Sharp corners are not supported because there is a risk of panel breakage. The key that circular arc Angle hits convex, the key life that beats convex than sharp Angle is longer. We suggest that if you want to make the key area of membrane switch protruding, remember to design the key corner rounded. Small corner, great wisdom. On the film panel convex, here is the introduction.
