Cherry key switches are the mechanical mechanisms beneath each keycap on a keyboard that register your keystrokes, and they determine how a keyboard feels, sounds, and responds. The right Cherry switch type for you depends on whether you prioritize typing comfort, gaming speed, or noise level. This guide explains how they work, compares the main Cherry MX variants, and helps you pick the best one for your needs.
What Are Cherry Key Switches?
Cherry MX switches are a family of mechanical switches manufactured by the German company Cherry (now part of the ZF Group). They were introduced in the 1980s and have become the industry standard for high-quality mechanical keyboards. Each switch is a self-contained unit with a spring, a stem, and internal contacts. When you press a key, the stem moves down, compressing the spring, and the contacts close, sending an electrical signal to the computer.
Unlike membrane keyboards that use a single rubber sheet, mechanical switches give each key its own independent mechanism. This results in a more consistent feel, longer lifespan (typically rated for 50 million keystrokes), and the ability to choose different tactile and auditory feedback profiles.
How Cherry MX Switches Work
Inside a Cherry MX switch, the keycap sits on a stem that slides up and down inside a housing. A metal spring provides resistance, and a small metal leaf (contact) is positioned near the bottom. When you press down, the stem pushes against the leaf, closing the circuit and registering the keystroke. The switch then returns to its resting position when you release the key.
The three main characteristics that differentiate switch types are:
- Actuation force: The amount of pressure (in grams) needed to trigger the keystroke.
- Actuation point: The distance (in millimeters) the key must travel before the keystroke registers.
- Tactile feedback: Whether you feel a bump (tactile), hear a click (clicky), or feel nothing until bottom-out (linear).
Cherry MX Switch Types Explained
Cherry offers several color-coded switch types, each with a distinct feel. The most common are:
- Cherry MX Red: Linear switch, no tactile bump, actuation force of 45g, actuation point at 2.0mm. It is smooth and quiet, making it popular for gaming.
- Cherry MX Brown: Tactile switch with a subtle bump, actuation force of 45g, actuation point at 2.0mm. It offers a balance between typing and gaming, and is a common choice for office use.
- Cherry MX Blue: Clicky switch with a distinct click sound and tactile bump, actuation force of 50g, actuation point at 2.2mm. It provides strong feedback but is loud, which may be disruptive.
- Cherry MX Black: Linear switch with a higher actuation force of 60g, actuation point at 2.0mm. It is heavier than Red, requiring more pressure, which some typists prefer.
- Cherry MX Speed Silver: Linear switch with a shortened actuation point of 1.2mm and 45g force. It is designed for fast double-tapping in games.
- Cherry MX Silent Red: Similar to Red but with internal dampeners to reduce noise at bottom-out and return.
Other less common types include MX Clear (tactile, heavier), MX Green (clicky, heavier), and MX White (clicky, light).
How to Choose the Right Cherry Switch for You
Your choice depends on your primary use and personal preference. Consider these factors:
- Typing vs. Gaming: For typing, tactile or clicky switches (Brown or Blue) give you feedback that helps avoid typos. For gaming, linear switches (Red or Speed Silver) allow faster, smoother key presses.
- Noise sensitivity: If you share an office or room, choose quieter switches like Red, Brown, or Silent Red. Blue switches are loud and may annoy others.
- Finger strength: Heavier switches (Black, Clear) require more force, which can reduce accidental presses but may cause fatigue. Lighter switches (Red, Brown) are easier to press.
- Budget: Cherry switches are premium, so keyboards with them cost more. If budget is a concern, consider alternatives like Gateron or Kailh, which are often cheaper but similar in feel.
If possible, try a switch tester or visit a store to feel the differences before buying.
Common Issues and Misconceptions
One common misconception is that Cherry switches are the only good mechanical switches. While they are high-quality, many other brands offer excellent alternatives. Another myth is that linear switches are bad for typing—this is subjective; some typists prefer the smooth action.
Common issues with Cherry switches include:
- Switch chatter: A switch registers multiple keystrokes from one press. This can be caused by dust or wear, and sometimes fixed by cleaning or replacing the switch.
- Keycap wobble: The keycap may feel loose if the stem is not perfectly stable. Cherry switches generally have low wobble, but it can vary.
- Lubrication: Some users lubricate switches to reduce friction and noise. This is a modding practice, not required for normal use.
Cherry vs. Other Mechanical Switch Brands
Cherry switches are the benchmark, but other brands offer comparable options at lower prices. Gateron switches are often considered smoother and cheaper, while Kailh offers a wide variety of innovative designs. Outemu is another budget option. When comparing, look at the force, actuation point, and feel—these are more important than the brand name.
Cherry’s advantage is consistency and reliability, but many users find that cheaper clones perform nearly identically. It is worth reading reviews and trying different switches if you are not sure.
Cost and Lifespan
Cherry MX switches are rated for 50 million keystrokes, which is significantly more than membrane keyboards (typically 5-10 million). This longevity justifies the higher cost for many users. Keyboards with Cherry switches typically range from $80 to $200, depending on the brand and features. Switches themselves cost around $0.50 to $1 each if you build your own keyboard, but this requires soldering and other components.
Frequently Asked Questions
Are Cherry MX switches worth the extra cost? Yes, if you type or game for long hours. Their durability and consistent feel can reduce fatigue and improve accuracy. However, if you are on a tight budget, cheaper alternatives may be sufficient.
Can I replace Cherry switches in my keyboard? It depends. If your keyboard has hot-swappable sockets, you can easily pull out the switch and insert a new one. Otherwise, you will need to desolder and solder, which requires skill and tools.
What is the difference between tactile and linear switches? Tactile switches have a noticeable bump when the key registers, giving you physical feedback. Linear switches have no bump; they move straight down smoothly. Clicky switches are tactile but also produce a click sound.
Are Cherry MX Blue switches too loud for an office? Yes, they are among the loudest switches. If you work in a shared space, consider Brown or Red switches to avoid disturbing colleagues.
Which Cherry switch is best for gaming? Many gamers prefer Red or Speed Silver for their linear action and low actuation force, which allow rapid presses. However, some gamers prefer tactile switches for better control. It is a matter of personal preference.
Do Cherry switches require lubrication? No, they work fine out of the box. Lubrication is an optional mod that can make switches smoother and quieter, but it may void warranties and requires careful application.
