How to identify the material of membrane switch and the method of identifying the material of membrane switch?

How to identify the material of membrane switch and the method of identifying the material of membrane switch? Today, the resplendence of membrane switch manufacturers brings us “Identification of membrane switch material method”, let you know before the membrane switch panel, can have more industry knowledge! Smell, pet plastic taste different from the usual plastic, one thing, smell pure pet plastic is aromatic, if pet plastic is rich in other ingredients, smell will be very bad. You can’t use a bottle with duct tape. Look at the burning plastic. If the product is black or has a drop of oil shortly after overheating, many melting points are abnormal. Pet materials are often plagued by this problem. When wire drawing, take a small piece of film with Fire Start Wire drawing observation, see wire drawing can be broken length, observe broken wire point, not rolled into a small circle, the higher the melting point of the product, the larger the volume. But usually if it’s bottled, it’s not a big deal. The key is to determine whether it is rich in pet plastic, the most important ingredient for pets. First take more samples, and then in the sunny shop, PVC in the Sun will generally be Pale blue. If there’s a white crease on the edge of half of it,. If you just look around and don’t have an accurate film switch, the material used to identify the film switch is largely based on personal experience.What is the principle of designing membrane switch interface? Membrane switch matching principle is what we usually call bijection, just like everyone in life has a name, imagine if there are two people with the same name in the same unit or group, there will be a match, that led to some bad behavior. The same is true for product design, such as a domestic gas stove, where two gas cookers are equivalent to two ignition switches. The ignition switch on the left controls the burner on the left, and the burner on the right controls the burner on the right. That’s normal. This is very consistent with people’s operating and cognitive habits, but if the switch function is interchangeable, the burner on the left can control the burner on the right. The right controls the left, which inevitably leads to confusion and error. Film switch, this matching principle in the film switch design application key, its electrical performance key classification and matching function can be summarized as the following points. (1) as far as possible a major function corresponding to a key, when the key is too many, can be appropriately based on the importance of the function of induction display. (2) the arrangement of keys, as far as possible according to the position of the corresponding components of the clothing or according to a certain condition, so that the user at a glance when using. (3) according to the function units in the interface, there should be clear distribution, such as display area, function selection area, input area, execution area, etc. .
