- Basic structural principles
Membrane keyboard
It primarily consists of five parts: the keycap, the volcano post (the connecting structure of the keycap), the silicone bowl (the rebound component), three layers of conductive film, and the base plate. There is no independent key support structure.
The three-layer conductive film serves as the core component. When pressing the button, the upper and lower conductive films are squeezed together to establish contact and trigger a signal. Upon releasing the keycap, the silicone bowl recovers its original shape due to its elasticity, causing the upper conductive film to separate from the lower one. This disconnects the circuit, and the keycap returns to its initial position, completing a button press cycle.
Scissor switch keyboard
Each keycap is equipped with a pair of cross-clamping plastic scissor brackets, paired with thin silicone spring clips; the vertical pressing stroke is stable, optimized for ultra-thin keyboard bodies.
Compared to membrane keyboards, the guiding effect of scissor brackets enables keys to be stressed more evenly and triggered more precisely. After releasing the keycap, the silicone bowl elastically resets, driving the scissor bracket to expand and smoothly push the keycap back to its initial position, completing the rebound. The linkage structure of the scissor bracket effectively disperses pressure, making the rebound more uniform and gentle, reducing finger fatigue.
Mechanical keyboard
Each key is equipped with an independent metal spring mechanical switch, relying on the spring to provide rebound, with metal contacts independently conducting; the body is thick, and the key travel is longer. Mechanical keyboards are representatives of high-end keyboards, with the core using independent mechanical switches as the triggering unit, completely different from the membrane triggering method of the former two. They are mainly focused on durability and distinct mechanical feel, and are commonly used in fixed scenarios such as gaming and heavy typing.
- Analysis of advantages and disadvantages
2.1 Membrane keyboard
Advantages
The production cost is extremely low, the production process is simple, and it is lightweight; it can be made into an inexpensive small folding keyboard for promotional gifts.
shortcoming
The product has a short service life, lacks an independent support bracket, and has poor button stability, prone to swaying side to side during rapid typing. The silicone bowl, being the main resilient component, tends to age and lose its elasticity after prolonged use, leading to loose button feedback. Despite its lightweight and slim design, the product feels soft and squishy in the hand, produces loud noise, and cannot meet high-precision and high-stability usage requirements.
2.2 Scissor-foot keyboard
Advantages - With low triggering noise and even rebound, it balances portability and user experience, making it the optimal choice for office and travel scenarios;
- The ultra-thin silicone bowl, paired with a compact stand design, allows the body to be extremely thin and lightweight, perfectly fitting various folding portable keyboard cases;
- The vertical limit of the keys is not shaky, significantly improving the stability of the keys. The rebound is soft and uniform, reducing finger fatigue from long-term typing;
- Balancing cost and service life, it is the optimal cost-effective solution for wholesale of folding office keyboards.
shortcoming
The lack of strong mechanical tactile feedback from mechanical switches cannot meet the needs of users who pursue a distinct mechanical typing experience. Its overall durability is also inferior to that of a fully mechanical structure
2.3 Mechanical keyboard
Advantages
Excellent long-term durability, unique spring-driven mechanical rebound. Different switch types can provide different tactile feedback, widely recognized by gaming peripheral enthusiasts.
shortcoming
The manufacturing cost is high. The bulky body cannot be designed into a foldable keyboard that fits in a pocket. In a quiet office space, the loud tapping sound can easily disturb the people around.
- Selection suggestions
Scissor-foot structure keyboard. If your core sales target is a portable folding keyboard for office, travel, and student groups, the scissor-foot structure is the optimal choice. This structure perfectly balances portability, quietness, typing experience, and procurement cost. The ultra-thin body can be adapted to various folding styles, and the low-noise design is suitable for quiet scenarios such as libraries and offices. The uniform rebound feel can meet the needs of long-term typing. Whether it is wholesale, retail, or custom branding, it can gain market recognition. It is also the core main structure of our folding keyboard.
Membrane keyboard. Only consider membrane keyboard when your target market is a low-price gift channel with strict budget constraints and low requirements for keyboard feel and stability. Its production cost is extremely low, making it suitable for bulk purchasing as promotional gifts. However, it is necessary to clearly inform customers of its shortcomings, such as a short lifespan and prone-to-shake keys, to avoid after-sales disputes.
Mechanical keyboard. Mechanical keyboards are suitable for people who rely on the tactile feedback of keystrokes. The tactile feedback, combined with the sound quality of keystrokes and various colored lights, makes them suitable for gaming keyboard scenarios. At the same time, their high production costs and loud keystroke noise are also incompatible with mainstream usage scenarios such as office work and travel with folding keyboards, and it is not recommended to include them in the procurement product line for folding keyboards.
In summary, the scissor-foot structure, with its core advantages of lightness, stability, quietness, and high cost-effectiveness, has become the preferred solution for peripheral equipment procurement. Our company can provide products such as folding keyboards and desktop keyboards with scissor-foot structure, supporting OEM & ODM.
