MEMBRANE SWITCH

What is a Membrane Switch?

Membrane switch productsare everywhere, but not everyone is familiar with them. So, What is a Membrane Switch? A membrane switch is a momentary electrical switch that is used to turn a circuit on and off. It consists of several layers of flexible materials with printed circuits. These switches are widely used in various applications such as industrial controls, medical devices, and consumer electronics. Importance of Membrane Switches can be gauged from the fact that they provide a reliable and cost-effective solution for enabling user-interface with electronic devices.

Three Common Structures of Membrane Switches

Backplane Selection

Aluminum: This is a lightweight and durable material that is commonly used for backplates. It is resistant to corrosion and can be easily machined and customized.

Stainless Steel: This is a strong and durable material that is resistant to corrosion and abrasion. It is heavier than aluminum and is commonly used in applications that require a higher level of durability.

Plastic: This is a lightweight and cost-effective material that is commonly used for backplates. It is less durable than metal, but is suitable for applications that do not require a high level of durability.

What Makes Membrane Switch Popular?

Large membrane switchare popular for various reasons:



Ease of Use

Large area membraneswitchesare incredibly user-friendly. They can be designed to incorporate graphic overlays, making them intuitive to use even for first-time users.

Reliability

These switches are known for their reliability. They can withstand a high number of cycles without showing signs of wear and tear.

Durability

One key membrane switchare resistant to harsh environments, including extreme temperatures, moisture, and chemicals.

Versatility

They can be customized to fit a wide range of applications, making them suitable for various industries.

What Is a Custom Membrane Switch Buttons Used For?

Consumer Electronics

Industrial Control Panels

Medical Equipment

Automotive

Aerospace and Aviation

ATM and Point-of-Sale (POS) Systems

Military and Defense

Appliance Control Panels

Security Systems

Why Use the Membrane Keypad Made by Niceone-Tech?

Niceone-tech can customize products that are perfect and best suited to customer requirements according to customer needs. In order to let you know how the best and most suitable membrane switch is produced, we must talk about its structure:

Overlay-Polyester

Overlay-Polyester is usually the first choice for membrane switchpanel materials, because its life will be a little longer than Polycarbonate. If it is simply a panel instead of a membrane switch, Lexan and Polyester are also good choices. Overlay is the most intuitive form of human-machine interface. Niceone-tech will screen print or digital print on the back of the material, and they can also be used in combination. Special requirements such as mirror silver effect are also feasible.

Overlay Adhesive

As the first layer of adhesive paper under the panel, Acrylic adhesive is usually used, generally the thickness is between 0.125-0.225mm. If it is LGF membrane switch (to LGF membrane switch) structure, the thickness sometimes reaches 0.64mm.

Top Circuit Layer (Dome Retainer)

This layer usually has three functions: 1. As the Dome Retainer, it ensures that the Snap dome of the circuit layer will not form shrapnel movement due to triggering and closing, resulting in circuit failure and circuit wear. 2. Use 0.1-0.125mm Polyester printing conductive ink, carbon oil and UV ink as the upper line. This layer structure can also be convex to make tactile feedback better. 3. Can be used as ESD shielding layer.

Circuit Spacer (Switch Spacer)

Both upper and lower lines are printed with conductive ink, usually thicker tape is used to separate the upper and lower lines to avoid direct conduction of the membrane switch. If the upper circuit is only used as a fixed layer, then the general thickness of Overlay adhesive + Top Circuit Layer + Lower Circuit Layer should be greater than 0.4mm, otherwise the panel will squeeze the shrapnel to make the feel worse. Unless the panel is convex, the four-layer structure is less than 0.4mm.
