Types of Mouse Switches

When it comes to choosing the right mouse for your needs, one crucial aspect to consider is the type of switch it uses.

Mouse switches are the heart of any mouse, and they play a vital role in determining the performance and feel of your mouse.

Whether you’re a gamer, a graphic designer, or a writer, understanding the types of mouse switches can help you make an informed decision when selecting your next mouse.

So let’s get started.

What Is a Mouse Microswitch

A mouse microswitch, also known as a mouse button switch or mouse click switch, is a critical component inside a computer mouse that registers the clicking or pressing of a mouse button. These switches are responsible for transmitting the electrical signal to the computer when you physically press one of the mouse buttons, such as the left-click or right-click buttons.

Microswitches are designed to provide tactile feedback and audible clicks when activated, giving users a sense of interaction and control. They are known for their durability and reliability, as they are built to withstand the repetitive clicking that occurs during everyday computer use, including tasks like clicking on icons, selecting text, or gaming.

Inside a microswitch, there are mechanical components that come into contact when the button is pressed, completing an electrical circuit. This action sends a signal to the mouse’s electronics, which then communicates with the computer to perform various functions, such as opening applications, selecting items, or executing commands.

The quality of the microswitches used in a mouse can significantly affect the user experience. High-quality microswitches are designed to be responsive, provide consistent feedback, and have a longer lifespan. Manufacturers often specify the type and brand of microswitches they use as a selling point for their mice, catering to users who have preferences for different click feel and actuation force.

Difference Between The Switch And Microswitch

The terms “switch” and “microswitch” both refer to electrical components used to control the flow of electricity in electronic devices, but there are key differences between the two


A switch is a fundamental electrical component designed to control the flow of electricity within an electronic circuit. It can be categorised into various types based on its design and operation, but the core function remains the same: to open or close a circuit to either allow or interrupt the passage of electrical current. 

Switches come in a wide range of sizes and forms, from large toggle switches found in household appliances to small push-button switches used in everyday electronics. 

They can be operated manually, by physical manipulation like flipping a toggle or pressing a button, or electronically through semiconductor devices like transistors. 

The application of switches is diverse, spanning household appliances, industrial machinery, lighting systems, and electronic devices, allowing users to control power, functionality, and settings with ease.


A microswitch is a specialized type of switch, typically characterized by its small size and precision in operation. 

These switches are designed to provide a highly reliable and distinct switching action when a specific force is applied to the actuator, often in the form of a button or lever. 

The key feature of a microswitch is its snap-action mechanism, where the contacts inside the switch quickly snap open or close, ensuring a well-defined switching point. 

This makes microswitches particularly suitable for applications where precision, reliability, and tactile feedback are essential. 

Common applications of microswitches include electronics, automotive devices, vending machines, computer mice (for the click buttons), and any scenario where precise control and dependable switching are required, often with the added benefit of audible clicks and tactile feedback for user assurance.

How Many Switches Are There In A Mouse?

In a typical computer mouse, there are usually two primary buttons, which are the left-click and right-click buttons. 

However, some mice may have additional buttons, such as side buttons or a clickable scroll wheel, adding to the overall functionality. The number of buttons can vary depending on the mouse’s design and intended use, with gaming mice often featuring more programmable buttons for additional functions.

The common applications of the mouse buttons are:

Left-Click Button: When you press the left-click button on a mouse, it activates a brief electrical signal. This signal is transmitted to send a command to the computer, typically interpreted as a left-click action. This is how you select items, open files, or interact with software by clicking on icons or buttons.

Right-Click Button: The right-click button operates in a similar manner to the left-click button but is typically associated with different functions, such as opening context menus or performing secondary actions in software. 

Scroll Wheel/ Button: This button is often found in the centre of computer mice and serves as a versatile input tool. It is primarily used for vertical scrolling in various applications. In web browsers and documents, users can scroll up or down to navigate content quickly. In image editing software, the scroll button can zoom in or out. It’s also employed in gaming for tasks like weapon selection or zooming in on a character’s perspective.

Optical vs. Mechanical Switches

If you are familiar with gaming mice, you’re likely aware of the current popularity of optical mouse switches. 

But, are they a great substitute for mechanical switches? 

Let’s explore the key differences and strengths of each switch type.

What Are Mechanical Switches

Mechanical mouse switches are a type of switch used in computer mice, particularly in gaming mice. 

These switches are designed to provide tactile feedback and a distinct click feel when the mouse buttons are pressed.

Beneath each mouse button, there’s a tiny switch waiting to spring into action. When you click a button, a specific part of it gently pushes down on this switch. Inside that switch, there’s a slender piece of material (often called ‘shrapnel’) that moves to create contact. Once contact is made, it sends a signal to your computer, like telling it, “Hey, I’ve been clicked!”

This mechanical process is wonderfully simple and effective for registering button clicks. It’s cost-effective to produce and, depending on how well it’s made, can result in switches that work really well. But, like anything, there are a few downsides to using mechanical switches.

You can Comprehend it more vividly from this video.

Mechanical mouse switches offer several advantages such as tactile feedback, faster response time, and durability. 

However, there are two distinct drawbacks to these switches, prompting the need for optical switches.

  • There’s a need for debounce delay to prevent accidental double clicks
  • They require contact to send a signal, and as such there’s going to be wear and tear

What Are Optical Switches 

Optical mouse switches, also known as light-based switches, are a type of switch technology used in computer mice, particularly gaming mice. Unlike traditional mechanical switches that rely on physical contact and actuation, optical switches use light to register button presses. 

This technology offers several advantages over traditional mechanical switches, including increased accuracy, durability, and reliability.

In the example below you can see a beam of infrared light that gets interrupted whenever the button gets pressed. Every time this beam gets interrupted, a signal is sent to the PC.
