Membrane Switch is a common electronic component. Usually consisting of a Membrane Switch circuit board and buttons, it has the following advantages. The highly sensitive membrane Keyboard switch uses a non-contact design, which allows you to touch the switch and mechanical switch with a single touch. In contrast, thin-film keyboards are more sensitive if they have less trigger force. Small volume film switches use film wire design compared to mechanical switches. It is smaller and can accomplish more functions in a limited space. Good durability membrane switch Keypad switch using polymer material film line, high temperature resistance, wear resistance, corrosion resistance and other advantages, so very durable. Simple operation Diaphragm opening and closing operation is very simple, just a touch to open, very suitable for some frequent operation occasions. Easy installation The installation of the film opening and closing device is very convenient, just the film wire is fixed in the corresponding position, do not need to take up more space like the mechanical opening and closing device.
