Everything That You Need To Know About LGF membrane switch

LGF membrane switch has proven itself an ultimate solution for consistent backlighting. A type of illumination introduced in LCDs – in membrane switches. Its essence complements consumers’ demand, like thinner, sophisticated, and advanced lighting, to enrich their products' lighting effect.

Before we move ahead, we should know what LGF technology is. LGF stands for Light Guide Film. It is primarily a thin film backlight technology that guides the light produced through right-angle LEDs or side-firing through sections where you need uniform backlighting. Regardless of the type of an outline of any area.

When applied in membrane switches, the technology proliferates users’ experience when they get uniform backlighting lighting across several areas within the switch. It is because of this reason that manufacturers integrate dazzling colored backlighting into their products’ membrane switches so that they look distinguished from their competitors.

Before we move ahead, let us first understand a membrane switch, backlighting, and then we will look into the integration of the LGF technique in membrane switches.

Membrane Switch Backlighting

In the fast-moving technological world, many working environments use equipment operated in little light or even in dark surroundings. Such places prefer to use backlit membrane switches. The glare and keys of such membrane switches remain stable and long-standing.

Unlike conventional mechanical switches made of plastic buttons and include copper wires, LGF membrane switches have printed electronic circuits.

They allow the users to direct instructions to the devices in a convenient manner. They have transparent, concrete, or dead-front icons printed on their upper surface. Backlighting is an advanced lighting solution in which lights are placed under a membrane switch so that the users can easily read the icons displayed on the keypad. Lighting used in the membrane switches shows that the device has received and accepted the instructions.

The backlit membrane switch is an economical and thriftily standard backlit option among many industries involved in manufacturing medical appliances, LCDs, automation, aero spacing, personal safety kits, and badges, etc.

How the Technology Works?

To meet the market's inescapable demand for innovative membrane switch, the experts have shaped the conventional control with a new lighting solution called the light-guiding technology. This technology uses the reflection of light to project the backlighting outcome.

The makers have kept the sleekness of the membrane while placing a .005 to .020 inch thin layer of film (commonly known as light guide film) under the membrane switch to illuminate its background unvaryingly. Due to this film's fine quality, it is virtually possible to contrive the membrane switch into any shape.

The thin film layer has microdots integrated into it and pressed on to points, also called imaged areas, illuminating the supply of power. The backlighting transpires by a printed circuit with LEDs positioned directly below the light guide film.

The side-view LED produces light beams that pierce through the thin film and strike the microdots. With such a mechanism used in the backlit membrane switch, the makers have ensured that the light beams divert upwards towards the membrane’s surface.

As a result, light distributes uniformly to directed areas through the plastic film, and the users can conveniently recognize the illuminated buttons on the membrane switch. The fineness of the film safeguards the uniformly real feel of the controls. The buttons on the membrane switch can either illuminate individually or all at once as per the action taken.

Benefits of LGF Membrane Switch

User friendly and easy to operate

This membrane switch is easy to operate and usually free from causing any intermittent issue.

Uniform and uninterrupted dissemination of light

The cutting-edge technology used in the LGF membrane switch is an exceptional example of the human-machine interface and an impeccable solution for uniform lighting. The users can relish consistent lighting through one or more part within the membrane switch.

Precision and clarity

There is a better sense of course for the user. The membrane switch design ensures that the user can conveniently recognize what icons and keys complete what task on the equipment.

The illuminated icons are guiding the user on how to manoeuvre the device. So that they feel comfortable that their product functions appropriately and as anticipated. For instance, if the user presses a wrong button, it would illuminate in alarming light, indicating that the user should avoid pressing the button again.

Stability in fabrication

These sophisticated and smart lighting based panels are incredibly durable. In addition to providing proper illumination inconceivably, these switches do not vitiate over time. The users have the flexibility to wash the board without any harm to it.

Low emission of heat

Since nominal voltage must illuminate the LEDs placed beneath the finely made thin light guide film, these switches create little heat.

Resilience

The industrial equipment needs extra moisture resistance. Take, for example, the treadmill in fitness and health equipment. These machines must be anti-corrosion, and therefore, use membrane switches.

The reason is that the high-life-span membrane switch is wonderfully resilient. It is impervious to breaks and cracks, and possesses the right tightness. It is moisture-proof, withstands water and abrasion, anti-dust, anti-rust, and even acid-proof. In other words, this switch is safe and dependable.

Attractiveness and aestheticism through diversity in colors

Due to availability in multiple colors, the backlit membrane switch can add a sense of aestheticism to users’ tastes. The beautiful look with bright and rich colors supplemented by random design of the membrane switch mirrors the product's discrete style.

Summary

An efficient, discrete, and worthwhile LGF membrane switch is a seamless panel. It outfits the surfaces of products that need illumination. Especially when the product is thin and compact.

The enhanced luminous distribution in a precise manner and availability in multiple colors makes it an incredibly top choice backlit switch. The tactility of the switch buttons remains unaffected due to the fantastic technology dipped in its built.

The switch’s durability, sleekness, and reduced power consumption are the added qualities. Thus, making it aesthetically pleasing for years and significantly speak of its priceless reliability. The membrane switch can adjust to any product.
