## Summary description

The Razer RC21-02040100-R3M1 key switch features a transparent yellow design and comes in a pack of 36. Ideal for customizing your mechanical keyboard, these switches provide a unique aesthetic and responsive performance for gamers and typists alike.

## Long description

The Razer RC21-02040100-R3M1 Transparent Yellow key switches are mechanical keyboard switches sold in a pack of 36 designed for customizing desktop mechanical keyboards. These transparent yellow switches combine visible housing aesthetics with standard mechanical switch dimensions, allowing replacement or modification of key modules on compatible hot-swap or solder-style PCBs. The transparent housing enhances backlight diffusion while the switch mechanics deliver tactile or linear actuation depending on the internal design, providing consistent keypress feel for gaming and typing sessions.
Advantages
Transparent yellow housings improve RGB and LED light transmission for clearer, more even backlighting across keycaps. The pack of 36 is convenient for partial keyboard modifications such as customizing a single row, keypad, or macro cluster without purchasing a full set. These switches are made to match common mechanical switch form factors, simplifying installation on compatible switches or standard MX-compatible stems and plate designs. Durable construction supports repeated keypress cycles and consistent performance over extended use.
Suitable for
 Customizing mechanical keyboards with a transparent yellow aesthetic
 Improving RGB/LED backlight diffusion under keycaps
 Replacing worn switches in a compact area or single zone
 Building a small custom keypad, macro pad, or gaming cluster
Key specifications
 Pack quantity: 36 key switches
 Housing color: transparent yellow
 Compatibility: MX-style stem and standard mechanical switch housings (for compatible keyboards)
 Intended use: mechanical keyboard customization and replacement
 Lighting: transparent housing for enhanced light transmission
How to use
Before installation, verify compatibility with your keyboard's switch type (hot-swap socket or soldered pins) and remove keycaps using a keycap puller. For hot-swap sockets, align the MX-style stem of each switch with the socket and press firmly until it seats. For solder-style PCBs, desolder the existing switch and solder the replacement following standard electronic soldering safety procedures. After installing the switches, reattach keycaps and test each key in your operating system or keyboard configuration software to confirm correct actuation and lighting behavior.
Usage recommendations
Handle switches by the housing to avoid contaminating internal components. Use compatible keycaps and stabilizers where required. When soldering, use proper tools and ventilation. For optimal lighting effects, pair the transparent yellow switches with RGB or single-color LED backlighting and compatible keycaps that allow light transmission.
