Membrane switches are widely used and can be seen everywhere in life. They can be seen in the refrigerator shell, microwave oven surface, washing machine button, rice cooker button, remote control shell and other daily necessities. The membrane switch can be divided into two types structurally, the convex membrane switch and the plane membrane switch. As a membrane switch manufacturer, it should meet the following conditions:
Membrane switches are widely used and can be seen everywhere in life. They can be seen in the refrigerator shell, microwave oven surface, washing machine button, rice cooker button, remote control shell and other daily necessities. The membrane switch can be divided into two types structurally, the convex membrane switch and the plane membrane switch. As a membrane switch manufacturer, it should meet the following conditions:
1. Good dimensional stability: it is required to make the film of the panel without obvious change in size within a certain temperature range (generally - 40 ℃~55 ℃).
2. Good appearance: the film surface of the panel is flat and glossy, without damage, scratches, inclusions, etc.
3. Elastic requirements: the thin panel layer is required to have a certain weakening performance, which can be judged by the elongation of the material. Generally speaking, the elongation is large, and the elastic deformation is also large, and vice versa.
4. Good weather resistance: The panel layer is the surface layer of the membrane switch exposed in the natural environment, and its panel material will not deform, crack, age and discolor under certain natural environment conditions.
5. Good chemical resistance: the membrane switch layer may touch different chemicals, but for most common chemicals, mineral oil should have a certain tolerance.
The keys on the surface of the former are slightly bulged in the design, and the part of the keys is slightly higher than the other panel parts, presenting a three-dimensional panel. This type of membrane switch has certain advantages. Users can accurately find the position of fitness.
