Join us on this enlightening journey as we uncover the world of tactile switches and how they redefine the very essence of typing. Your keyboard experience will never be the same again.
What is a Tactile Switch?
What is a tactile switch? Simply put, a tactile switch is one whose function can be felt by touch. It is a well-known kind of electrical switch that is activated manually to complete or interrupt an electrical circuit. The characteristic tactile bump you experience when touching a tactile switch gives them their name.
These switches are designed to be audible enough so as not to disrupt the surroundings. Of all mechanical switches, tactile switches provide the best feedback.
However, tactile is not the only type of switches. In fact, there are many other sorts and the secret behind mechanical keyboard switches can be absolutely surprising.
Characteristics of Tactile Switches
When the key is pressed, this tactile switch would provide physical feedback to the user through a tactile bump or click sensation. Moreover, not only in tactile switches but also clicky ones can you find tactile bumps.
A small clicky sound and a bump of varied proportions are produced by tactile switches. The bump gives users a tactile sensation, allowing them to feel and know that the keypress has been successfully activated.
The actuation point is the crucial phase of the switch’s travel where the key or button makes contact, completing an electrical circuit. When the button reaches this point, it requires a specific amount of force, known as the actuation force, to register the keystroke. The user feels a tactile bump or click at this point, providing feedback that the key press has been recognized.
In the context of tactile switches, actuation force determines the level of pressure required for the switch to activate and send a signal to the device it’s connected to. It can vary from light to heavy, offering different levels of resistance.
Actuation force is typically measured in grams (g) and can vary significantly between different tactile switches. Some switches have a light actuation force, requiring less pressure to register a key press, while others have a heavier actuation force, demanding more pressure.
Total Travel Distance
Total travel distance refers to the complete distance that the switch’s button travels from its initial resting position to the bottom of the switch when fully actuated. It is a crucial characteristic that determines the physical depth or distance the key or button needs to be pressed before the switch registers the keystroke.
The total travel distance can vary between different tactile switches. Some users prefer a shorter travel distance for quicker keystrokes and potentially increasing typing speed, while others may find a longer travel distance more comfortable.
Depending on the design, tactile switches can produce different levels of sound when pressed. Some people enjoy the audible feedback as it provides a satisfying typing experience, and the click sound can help in confirming key presses.
On the other hand, some users prefer quieter switches, especially in shared or quiet environments, to reduce noise and potential distractions.
Tactile switches come in different profiles, such as Cherry MX, Kailh, or Gateron. Each profile may have slight variations in the design and characteristics of the tactile feedback.

- Round/Square/Rectangular: These terms refer to the physical shape of the tactile switch. Depending on the application and design requirements, tactile switches can come in different shapes.
- Flush: Flush tactile switches are designed to have a smooth and even surface when installed, without any protruding elements.
- Illuminated: Illuminated tactile switches have built-in LED lights that illuminate when the switch is activated, providing visual feedback or enhancing the aesthetics of the device.
- Miniature/Micro: Miniature and micro tactile switches are compact versions of tactile switches designed for applications with limited space. As their name suggests, they are commonly installed in small electronic devices and compact keyboards.
- Right Angle: Right-angle tactile switches have their terminals oriented at a right angle to the switch’s body. This type is more preferable for PCB (printed circuit board) mounting applications.
- Long Stroke: Long stroke tactile switches have a longer key travel distance, providing a more substantial tactile feel and feedback during typing or actuation.
- 5-Way: 5-way tactile switches are designed with multiple actuators, allowing them to be pressed in different directions (up, down, left, right, center). They are often used in gaming controllers or other applications that require multiple input directions.
- Switch Arrays & Keypads: These are configurations where multiple tactile switches are arranged in an array or grid to form a keypad or control panel. Switch arrays and keypads are commonly used in various electronic devices for user input.
How does a Tactile Switch Work?
A tactile switch operates through a mechanism that generates a noticeable physical feedback, or “tactile bump,” when the switch is pressed. This feedback is designed to provide users with a clear indication that the switch has been activated, which can be particularly beneficial for typing and other input tasks. Here’s how a typical tactile switch works:
Tactile Switch Structure
Tactile switches have a simple yet effective structure that enables them to provide tactile feedback and register keystrokes or inputs. The basic structure of a tactile switch typically includes the following components:
- Top Cover: The top cover is the visible part of the switch that users interact with. It serves as the outer shell, providing protection and support to the internal components. The top cover is designed to withstand repeated keypresses and external forces.
- Plunger: The plunger is a small rod or stem located below the top cover. When you press the button or actuator on the top cover, the plunger is pushed down, creating the downward force needed to activate the switch.
- Contact Dome: The contact dome, a vital part for tactile feedback, is a thin, flexible metal piece shaped like a dome. Pressing the plunger collapses it onto the conductive pad, completing the circuit and registering the key press, creating the user’s tactile feedback.
- Molded Resin Base: The molded resin base is the bottom part of the tactile switch. It is a plastic base that houses the contact dome and provides structural support to the switch. The base is essential for keeping all the internal components in place and ensuring the proper alignment of the switch.
Tactile Switch Operation
Imagine typing on a keyboard that lacks that satisfying tactile feedback. To prevent such a scenario, let’s start by answering the question: What is a tactile switch? and How does this switch function?
The basic working principle of a tactile switch involves a metal spring and two electrical contacts separated by a non-conductive material. Here’s a step-by-step explanation of how it works:
Resting Position: When the switch is at rest, the metal spring holds the movable contact away from the stationary contact, creating an open circuit. This position deters the flow of electrical current through the switch.
Application of Force: When you press the key or button, an external force is applied to the switch’s actuation point.
Compression of the Spring: As you apply force, the metal spring inside the switch begins to compress. The spring exerts an opposing force against your press, creating a resistance.
Actuation Point: As you press further, the spring reaches a critical point of compression. At this point, the movable contact swiftly connects with the stationary contact, completing the electrical circuit.
Tactile Bump: The moment of contact between the two electrical contacts creates the tactile feedback, resulting in a noticeable bump or click sensation under your finger.
Registered Press: Once the electrical circuit is closed, the switch sends an electrical signal to the connected device (e.g., computer, gaming console) to register the keystroke or button press.
Return to Resting Position: When you release the key or button, the spring returns to its original shape, pushing the movable contact away from the stationary contact, and the circuit is open again.
Pros and Cons of Tactile Switches
Tactile switches offer both advantages and disadvantages, depending on the application and user preferences.
Enhanced Typing Experience: Tactile switches provide a satisfying tactile bump or click, enhancing the typing experience by providing feedback on each key press.
Improved Accuracy: The tactile feedback helps users to precisely feel the actuation point, resulting in improved typing accuracy and reduced errors.
The tactile bump or feedback in some tactile switches may require more force to actuate, potentially leading to increased finger fatigue during prolonged typing sessions.
Quieter Than Clicky Switches: Tactile switches are generally quieter compared to clicky switches, making them more suitable for quiet environments or shared spaces.
Unlike clicky switches, tactile switches do not provide a distinct audible click sound, which may be preferred by some users who enjoy the audible feedback while typing.
Voltage and Current Rating
