1. What are Mechanical Switches?

Mechanical switches are the components located beneath each key that activates a keystroke when pressed.

Exploring the Components of a Mechanical Switch

Diving into the anatomy of a mechanical switch reveals the intricacies that make each keystroke precise and satisfying. Here’s a breakdown of the main components and their significance:

Delving into Mechanical Switch Components and Their Roles

While the keycap itself isn’t a component of the mechanical switch, it plays a crucial role in the auditory feedback during a keystroke, particularly when the key is fully pressed down.

The Stem

The stem’s design directly influences the switch’s actuation and travel distance, crafting the unique feel of each keystroke and defining the type of switch—be it linear, tactile, or clicky.

The Upper Housing

Serving as both protection and guidance for the stem, the upper housing is also the component that interacts with the keycap during a press, contributing to the switch’s overall feel and sound.

The Coil Spring

The spring underneath the stem provides the necessary resistance for key actuation. Its tension determines the force required to press the key and assists in returning the key to its initial position after release.

The Base Housing

Acting as the foundation, the base housing secures the upper housing and is the component that mounts directly to the keyboard’s PCB (Printed Circuit Board), ensuring stability and precise alignment.

The Crosspoint Contact

This small, often metal or gold, component is critical for the electrical functionality of the switch. Depressing a key causes the contact mechanism to connect with the PCB, completing the circuit and registering the keystroke.

Understanding these components sheds light on the complexity of mechanical switches and their contribution to the typing experience, from the tactile response to the sound and feel of each keystroke.

2. Types of Mechanical Switches

Mechanical switches come in three primary types: linear, tactile, and clicky, each distinguished by its unique keystroke behavior.

Clicky switches operate similarly to tactile ones, with the added feature of producing a distinctive “click” sound upon activation. They are perfect for users who appreciate a clear auditory indication of a keypress and enjoy the characteristic “clicky” noise.

3. Understanding the Characteristics of a Mechanical Switch

Grasping the characteristics of a mechanical switch extends beyond just the feel of the keystroke. There are five key technical aspects to consider, each impacting your typing experience and the functionality of your keyboard.

Depending on your typing style and the intended use of your keyboard, specific values for these characteristics may be more suitable for you.

Operation Force: This measures the amount of pressure required to depress a key, indicating how hard you need to press. Operation force is quantified in centinewtons (cN) or gram-force (gf), with 1 gf being almost identical to 0.98 cN. Therefore, a switch with an operation force of 50 cN essentially requires 50 gf of pressure.
Activation Point: This is the critical juncture at which the keyboard registers a keypress, measured in millimeters. Also referred to as the Actuation Point or Operating Position, it’s vital for understanding how far a key needs to be pressed before it responds.
Total Travel Distance: This represents the full range of movement a keycap can make until it bottoms out against the switch’s upper housing, measured in millimeters. It dictates the maximum depth your keystrokes can reach.
Tactile Position: Exclusive to tactile and clicky switches, this is the point during a key press where you can feel the characteristic bump, indicating a successful actuation. Linear switches, known for their smooth keystroke, lack a tactile position.
Reset Point: After pressing a key, this is the point where the key returns to its unactivated state upon release. Understanding the reset point is crucial for gauging how quickly you can repeat a keystroke.

These technical characteristics are fundamental to choosing a mechanical switch that aligns with your typing habits and preferences, ensuring an optimal typing or gaming experience.
