What are membrane switches keyboard?

Home » What are membrane switches keyboard?

Membrane switch keyboards are made based on membrane switches. When pressed, the rubber squeezes the membrane switch circuit, making the conductive lines on the upper and lower circuit layers contact, thereby generating an electrical signal. The bottom plate is the supporting part of the membrane switch keyboard. It is usually made of metal or plastic and is used to fix the membrane switch circuit and rubber and other components.

What is a membrane switch keyboard?

Membrane switch keyboard is an operating system that integrates key functions, indicating elements, and instrument panels. It is usually composed of four parts: panel, upper circuit, isolation layer, and lower circuit.

The membrane switch works through an overall sealed structure of a flat multi-layer combination. When the membrane switch is pressed, the contact of the upper circuit deforms downward and contacts the plate of the lower circuit. After the finger is released, the contact rebounds, the circuit is disconnected, and a signal is triggered.

Why are membrane keyboards so quiet?

The reason why membrane keyboards are quiet is mainly due to their working principle and structural design.

The working principle of membrane keyboards is different from that of mechanical keyboards. Mechanical keyboards use independent mechanical switches, and there is an independent switch under each key. It takes a lot of force to press, so it will produce a lot of noise.

The membrane keyboard uses a layer of soft membrane as a trigger mechanism. When the key is pressed, the membrane contacts the contact below to generate an electrical signal, thereby completing the input. This design makes the membrane keyboard significantly quieter than the mechanical keyboard when pressing the key.

In addition, the key material and structure of the membrane keyboard also contribute to its silent effect. The key material of the membrane keyboard is usually softer and has less pressing resistance. This design reduces the noise when pressing the key.

Why are membrane keyboards so cheap?

The main reasons for the low price of membrane keyboards include its low material and production costs, relatively simple production process, and the influence of market demand and positioning.

First of all, the structure of the membrane keyboard is relatively simple, and a layer of membrane is used as the key trigger device. This design reduces the complexity of production materials and processes, thereby reducing manufacturing costs.

In contrast, mechanical keyboards use independent mechanical switches as the trigger device for each key. These switches contain complex mechanical structures, and the manufacturing materials and processes are relatively complex, resulting in relatively high costs.

Secondly, the production process of membrane keyboards is relatively simple, and does not require complex mechanical processing and assembly processes, which makes its production efficiency higher and further reduces costs.

In addition, membrane keyboards usually use anti-fouling materials such as silicone and rubber, which are relatively low in cost and have good anti-oil, stain and other properties.

What is the disadvantage of membrane keyboard?

The main disadvantages of membrane keyboards include:

  • Low tactile feedback: membrane keyboards have no separate moving parts and have low tactile feedback.
  • Fast deterioration of feel: After long-term use, the keycaps of membrane keyboards will glow, become oily, and the elastic effect will deteriorate.
  • Lack of personalization: membrane keyboards are mostly produced through assembly lines, which are suitable for mass production, but not suitable for high-end customization and lack of personalized design.
  • Lack of high-end functions: Most membrane keyboards do not have high-end functions, which may not be enough for users who like to tinker with keyboards.

What are the uses of membrane switches?

The main functions of membrane switches include transmitting command information, controlling the switch status of the device, and providing a user interaction interface.

  • Transmitting command information: membrane switches realize the function control of electronic equipment through the conduction and disconnection of contacts. By pressing the membrane switch, the user transmits the operation instruction to the device to complete the functions of the device such as switching, starting, and stopping.
  • Control the switch state of the device: The membrane switch can control the on and off state of the device to ensure that the device works normally under the user’s operation.
  • Provide a user interaction interface: The membrane switch usually has a beautiful appearance and rich colors. It can be used as an operation panel of electronic equipment to provide an intuitive user interaction interface for user operation.

  • Durability and stability: The life of the membrane switch can generally reach more than one million times. Due to its compact structure and good sealing, it can work stably in harsh environments.
  • Waterproof, dustproof, and oil-proof: The membrane switch has good waterproof, dustproof, and oil-proof properties and can be used in humid and dusty environments.
  • Small size and light weight: The design of the membrane switch makes it small and light, suitable for use in various small electronic devices.

Membrane switches are widely used in electronic communications, industrial control, automotive industry, household appliances and other fields. Due to its compact structure, easy operation, and high durability, it has gradually replaced some traditional mechanical switches and become a common operating component in modern electronic devices.

What is the difference between a membrane keyboard and a normal keyboard?

Membrane keyboards and normal keyboards differ in many aspects:

1. Structural principle:

  • Membrane keyboards: They are composed of several layers of membranes, usually membranes with circuits, silicone layers, and metal plates.
  • Mechanical keyboards in normal keyboards: Each key has an independent mechanical switch, and there are contacts inside the shaft. When the keycap is pressed, the shaft generates an electrical signal to trigger.

2. Hand feel experience:

  • Membrane keyboards: The keys feel relatively light, the rebound force is small, the bottoming feeling is not very obvious, and the overall feel is relatively soft.
  • Mechanical keyboards in normal keyboards: Mechanical keyboards have rich and diverse feel and different hand feel characteristics.

3. Service life:

  • Membrane keyboards: Generally speaking, the life of membrane keyboard keys ranges from millions to tens of millions of times. After long-term use, problems such as key failure and poor feel may occur.
  • Normal keyboards: Mechanical keyboards have a long service life, generally exceeding 50 million key lifespans, and even some high-quality mechanical keyboards have a theoretical lifespan of hundreds of millions of keys.

4. Sound characteristics:

  • Membrane keyboard: The tapping sound is small, even close to silent, which is very suitable for use in places that require a quiet environment.
  • Ordinary keyboard: Mechanical keyboards will produce obvious sounds when tapping, especially the shafts with strong paragraph sense such as blue shafts, which have louder sounds and crisp and loud “click” sounds. This sound is a unique typing experience for some users, but it may be a disturbance for those who need a quiet environment.

5. Price difference:

  • Membrane keyboard: The manufacturing cost is low and the price is relatively cheap.
  • Ordinary keyboard: Due to the use of complex mechanical structure, high-quality materials and fine manufacturing process, the price of mechanical keyboards is usually higher.

6. Anti-interference

  • Membrane keyboard: The anti-interference ability is relatively weak, and it is easy to be disturbed by the outside world, and there may be false touches or key failures.
  • Ordinary keyboard: It has strong anti-interference ability and can still ensure normal use when it is disturbed by the outside world.

Why are mechanical switches better than membrane?

The reasons why mechanical switches are better than membrane switches mainly include the following aspects:

  • Clear feedback force and trigger point: Mechanical switches use mechanical parts, with clear key trigger points and obvious feedback force, which can provide better feel and keystroke accuracy.
  • Higher durability: Mechanical switch structure is more durable and can usually withstand more keystrokes. The mechanical switch life of mechanical keyboards can generally reach millions of keystrokes, while the life of membrane switches is relatively short.
  • Multi-key conflict-free technology: Mechanical keyboards usually have multi-key conflict-free technology, which can achieve simultaneous pressing of multiple keys without key conflicts.
  • More customizable: Mechanical keyboards usually have customizable functions, and keys can be set through software.
  • Application scenarios: Mechanical switches are suitable for occasions that require greater operating force or longer travel, such as some industrial control equipment and mechanical equipment. Membrane switches are suitable for occasions that require light touch operation, such as electronic products and household appliances.

In summary, mechanical switches have obvious advantages in feedback force, durability and customizability, and are suitable for scenarios that require high-precision operation and long-term use.

As a keyboard that uses membrane switch technology, the membrane switch keyboard has the characteristics and advantages of being light and portable, quiet and comfortable, waterproof and dustproof, and low cost, providing users with an efficient and convenient input experience.
