I am going to buy a keyboard recently. What are the advantages and disadvantages of mechanical keyboard and membrane keyboard? How to choose?

The mechanical keyboard is superior to the film keyboard in hand feel and service life. In the long run, mechanical keyboard is a better choice, but its price is much higher than that of membrane keyboard. If the budget is sufficient, you can buy a mechanical keyboard directly.

principle of operation

Membrane keyboard: Compared with mechanical keyboard, the design of membrane keyboard is very simple. The bottom layer is a circuit board with trigger keys, and the top layer is a key made of flexible materials such as rubber. Every time we press a key, we will squeeze the membrane keyboard, let the contact press on the circuit board and switch the circuit of the key. This design is cheap to make and copy, and it is also the originator of desktop keyboard.

Mechanical keyboard: Compared with membrane keyboard, mechanical keyboard will be more complicated in design. Each key has an independent switch under the key cap, which is also a mechanical device that will be activated when it reaches a threshold. This makes the design of mechanical keyboard very flexible.

Comparison of advantages and disadvantages

Advantages of the membrane keyboard: the design is simpler, and the noise will be very small when typing at high speed. Because the material is plastic, it will be lighter, smaller and easier to carry. Moreover, the film keyboard has a long history, and many manufacturers have made breakthroughs in feel and appearance, giving consumers a lot of choices and buying suitable keyboards at lower prices.

Disadvantages: Because the feedback of the trigger key is relatively simple, the response to the finger when typing is also very vague. Moreover, the key cap of the membrane keyboard is not detachable, and it is also difficult to clean up. After long-term use, the keys will inevitably be connected, and the service life is very short. Advantages of mechanical keyboard: the keys of mechanical keyboard are independent and the materials are more expensive. Each key will be tested 30-70 million times, while the membrane keyboard will only be tested 5 million times. Apart from these, the mechanical keyboard is basically not worn. After several years of use, the feedback of each case is the same as that of the first use. Due to the material relationship of mechanical keyboard, its weight is almost always higher than that of membrane keyboard, which also provides users with better stability and heavy feeling.

Disadvantages of mechanical keyboards: the price is often a serious injury to mechanical keyboards, and the price of a slightly better mechanical keyboard is several hundred. The mechanical keyboard is very playable. Many keyboards are equipped with tickers, which look good at night. Moreover, there are many axes to choose from. You can use the green axis for those who like paragraph sense, and the red axis for those who like straight up and down. Moreover, the collection value of mechanical keyboards is also very high. How to choose:

Membrane keyboard is a traditional keyboard, and it has not been greatly improved in use. If the budget is sufficient, you can choose a mechanical keyboard, but if you don't mind using the feel and life, you can choose a suitable membrane keyboard.
