Membrane switches can be made into flexible boards or used with hard board PCBs. The surface is generally made of materials such as PC or PET and printed with multi-color patterns to distinguish the different positions of each button.
The buttons of the membrane switch can be made into a convex shape or a flat shape. The surface of the membrane switch can also be made to have a high-gloss effect, or matte oil can be printed to give it a matte frosted effect.
Underneath the panel of the membrane switch is double-sided tape, bonding the panel and the circuit board below. Circuit boards can be made into single-layer, double-layer, or multi-layer structures. The circuit board is printed with conductive silver paste, UV insulating oil and anti-oxidation carbon paste. 3M glue can be printed on the back of the circuit board, or appropriate high-performance double-sided tape can be selected according to actual assembly requirements.
If the membrane switch needs to be backlit, or equipped with embedded LEDs as indicator lights for the buttons, the mezzanine of the membrane switch should be high to facilitate the storage of LEDs. The LED window can be made into a translucent effect. The LED emits light when working. When not working, the color of the window and the surface are the same, and the position of the LED cannot be seen, making the surface of the membrane switch more concise and beautiful.
Membrane switches with coarse sand surfaces are mainly used on large equipment. The edges of the buttons are made into arc-shaped protrusions to enhance the three-dimensional effect. The LED position is translucent, and the color is consistent with the background color of the panel. When the LED is not working, the LED cannot be seen. When the LED is working, the LED emits light to serve as an indicator.
Hotel light curtain control membrane switch, EL backlight, the product is thin, the light is even, and the font is translucent white when not lighting.
EL light source backlight membrane switch, this picture is the EL working lighting effect diagram, which requires the help of EL driver to work.
Membrane switch is a new type of switch that integrates surface appearance and key switch function. Membrane switch has gradually replaced traditional mechanical switches.Compared with traditional mechanical switches, membrane switches have a more rigorous structure, beautiful appearance, strong plasticity, good sealing performance, waterproof and dustproof, and long service life.Membrane switches can therefore be widely used in electronic communication products, electronic measuring instruments, medical equipment, automobile industry, household appliances, smart toys and other fields.
Raised flat membrane switch. High-end quality, built-in embedded metal dome switch. The product has a long service life. The high-convex translucent LED window is consistent with the background color of the panel when not emitting light, and displays the true color of the LED light source when working.
The membrane switch adopts an anti-scratch panel with a matte surface, built-in metal shrapnel buttons, round dome raised buttons, orange translucent LED window, and 2.54mm FPC pin female connector.
