The **KS2-05-R** refers to a high-quality, professional-grade **mechanical keyboard switch** manufactured by **Gateron**. These switches are part of the Gateron "KS-2" series, specifically the low-profile or standard variations known for their smoothness and durability. --- ### Technical Specifications The following table highlights the core electrical and mechanical characteristics of the KS2-05-R switch: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Linear (Red Switch) | | **Actuation Force** | 45 ± 15 gf | | **Pre-travel** | 2.0 ± 0.6 mm | | **Total Travel** | 4.0 ± 0.4 mm | | **Operating Life** | 50 million cycles | | **Contact Material** | Gold alloy | | **Housing** | Transparent (Top), Nylon (Bottom) | --- ### Electronic and Physical Composition The "R" in the model name typically signifies the **Red** variant, which is the linear version of this switch series. #### 1. The Contacts The KS2-05-R uses high-quality **gold-alloy contacts**. Gold is used because it is highly resistant to oxidation and corrosion, ensuring that the electrical circuit closes reliably over millions of keystrokes. #### 2. Mounting Type (3-Pin) This switch is typically a **Plate Mount** (3-pin) design. * **Center Post:** For stabilization. * **Two Metal Pins:** The electronic leads that complete the circuit when the switch is depressed. #### 3. SMD LED Compatibility The housing of the KS2-05-R is designed with a clear top or a specific cutout. This allows light from Surface Mount Device (SMD) LEDs on the keyboard's PCB to pass through the switch, illuminating the keycaps. --- ### Key Performance Benefits * **Smoothness:** As a linear switch, there is no tactile "bump" or click. The movement is a straight vertical press, making it ideal for gaming and rapid typing. * **Low Noise:** The internal dampening and material choice result in a quieter "thock" sound compared to Blue (clicky) or Brown (tactile) switches. * **Factory Pre-lubing:** Many iterations of the KS-2 series come factory-lubricated to reduce friction between the stem and the housing. ---
