Hoạt độngCherry MX Red Linear Keyswitch
Cherry MX Red — the original linear mechanical keyswitch.
Ứng Dụng Phổ Biến
The switch that started it all. Used in gaming keyboards, industrial keypads, POS terminals, and medical input devices. Linear action with no tactile bump. 100 million cycle rating. The MX crossmount stem design was patented in 1984, expired in 2014, enabling clones from Gateron and Kailh.
Cảnh Báo Hàng Giả High rủi ro
Cherry MX switches are the most counterfeited keyswitch globally. Fake Cherry MX Red switches are common on AliExpress and eBay. Genuine Cherry has crisp MX logo molded into the stem and specific tooling marks on the bottom housing. Fakes often have blurry logos, inconsistent spring weights, and rougher plastic. Buy from authorized distributors (Mouser, DigiKey) to guarantee authenticity.

Actuation Force
The force needed to press the button. Lower = more sensitive. Sanwa ~65g (light), Seimitsu ~85g (medium), Happ ~130g (heavy).

Certifications
Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.

Color
Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).

Mechanical Life
How many press cycles before mechanical failure. Higher is better — 10M cycles at 100 presses/day = 274 years.
|
100,000,000 cycles

Mounting Type
How the button attaches to the panel. Panel mount is standard — installs through a cutout from the front.
|
PCB mount / plate mount
|
|
Travel Distance
How far the button moves when pressed. Shorter = faster response. Sanwa 0.85mm is extremely short for competitive gaming.

Hướng Dẫn Cài Đặt Nhanh
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Khắc phục sự cố
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
