Find the perfect 3-pin switches for your mechanical keyboard. 3-pin, or plate-mount switches, are the most common switch type, offering a secure fit in keyboards with a switch plate. They provide excellent stability for a consistent typing experience, making them ideal for both custom and pre-built keyboards. Whether you are a gamer looking for speed or a professional seeking comfort, our collection features a wide variety of linear, tactile, and clicky 3-pin switches from top brands. Use KeebFinder's advanced filters to compare options and find the switches that meet your exact specifications for feel, sound, and performance.
Choosing the right switch is critical for your keyboard's performance and feel. This guide answers common questions about 3-pin switches to help you understand their design, compatibility, and best use cases, ensuring you make an informed decision for your next keyboard build or upgrade.
3-pin switches, also known as plate-mount switches, feature three main components that connect to the PCB: two metal pins for the electrical connection and a large central plastic post for stability. Unlike 5-pin switches, they lack the two extra plastic guide pins. Their stability comes from being mounted onto a metal or plastic plate within the keyboard assembly.
Use 3-pin switches in any keyboard that has a switch mounting plate. The plate provides the necessary alignment and structural support that is provided by the extra pins on a 5-pin switch. Since most commercially available and custom keyboards use a plate, 3-pin switches are a versatile and widely compatible option for many builds.
Yes, 3-pin switches are fully compatible with 5-pin (PCB-mount) hot-swap or solderable PCBs. The PCB will have holes for all 5 pins, and the 3-pin switch will fit perfectly. However, if you are building without a plate (a 'plateless' build), 5-pin switches are recommended for better alignment and stability, as they mount directly and more securely to the PCB.
Absolutely. A 5-pin switch can be easily converted to a 3-pin switch by simply clipping off the two smaller plastic guide pins with a pair of flush cutters or nail clippers. This modification makes the switch compatible with any 3-pin keyboard PCB or plate that doesn't have the extra guide holes. This makes 5-pin switches a more 'universal' option if you're unsure about future compatibility needs.
