What Is A Membrane Switch?

The membrane switch is an operating system integrating key functions, indicating elements and operation panel. It consists of panel, upper circuit, isolation layer, lower circuit event to the top layer of graphic overlay. Press the membrane key, the contact of the upper circuit deforms downward, and is connected with the electrode plate of the lower circuit. When the finger is released, the contact of the upper dome rebounds, the circuit is disconnected, and the circuit triggers a signal. The membrane switch has strict structure, beautiful appearance and good sealing performance. It is damp proof and has long service life. It is widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automobile industry, intelligent toys, household appliances and other fields.

The Benefits Of Membrane Switches

Small and portable: The weight of available membrane switches ranges from a few grams to dozens of grams, which is very easy to carry and disassemble.

Sealing: Using unique technology, the membrane switch can be waterproof, oil-proof and anti-pollution, but also it is anti-static interference and perform other functions.

Excellent electrical conductivity: the circuit of the switch can be printed with carbon paste, silver paste, some of them are embeded by copper and platinum etc. The conductive layer can be folded at will, and the resistance can be controlled to any resistance you want, and using a unique technology, the film made of The switch can control by coming through micro-electricity and system strong electricity power .Maybe receive high-voltage electric shocks of hundreds of thousands of volts without impairing its function. Reducing electicity shock attack to humen being as soon as possible !

Low cost: Compared with an electronic original device product with many functions, its price advantage is not comparable to other similar products.

Long service life: Because the material used in the membrane switch has good insulation, heat resistance and folding resistance, even though high resilience. it can print icons and graphic on the reverse side so that the screen printing pattern will not be damaged.

The Features Of Membrane Switches

1. Graphic Overlay: Polyester is frequently used to make graphic overlays because it has better chemical resistance and flex life than polycarbonate. To ensure you receive the right colors and textures, and finishes for your Silver Flex membrane switch design, Luphi can either electronic-print or screen print, or use a combination of both techniques.

2. Circuitry: The polyester film (PET), with good performance, is used as the carrier of the switch circuit pattern, and the conductive silver paste and conductive carbon paste are screen-printed on it with a unique process to make it conductive

3. Emboss: The three fundamental types of embossing are poly-dome, rim, and cushion. Logos and multi-level shapes can be embossed depending on their shape and size. Additionally, buttons can be embossed to offer a more tactile definition.

4. Backlighting options: A wide variety of backlighting options are available, LED, Light Guide Film (LGF), Electroluminescence (EL), and Fiber Optics.

5. Environmentally Sealing: A membrane switch can survive harsh conditions in the toughest environments. Such as UV resistant, temperature resistant, and chemical resistant.

6. Shielding: To comply with ESD, EMI, or RFI regulations, proper shielding is required.

The Most Common Types Of Membrane Switches

Capacity: We print the capacitive touch buttons/sensors on the PET circuit with transparent conductive ink.

Medical: These membrane switches meet ISO13485 standard.

PCB/FPC: The circuit of membrane switches can be flexible or rigid.

Rubber Keyboard: Silicone Rubber keypad switches are excellent for device operation controls. It is soft and elastic. It can give the user a very nice tactile feeling.

Waterproof: Meets IP67 and NEMA-4 waterproof standards.

Backpanel: back panel membrane switches or membrane keypads are flexible. Therefore, assembling it on top of any machine, equipment or device is possible.

Backlighting: LED backlighting, EL lamp, LGF(Light Guide Film) and Fiber backlighting.

Tactile Feedback: Tactile switches can be embedded into membrane switches and offer a snap-action feel to improve tactile feedback.
