Cherry MX Red Linear Keyswitch

Cherry MX シリーズ Introduced circa 1984

Cherry MX Red — the original linear mechanical keyswitch.

主な用途

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.

模倣品に関する注意 High リスク

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.

取付クイックリファレンス

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.

トラブルシューティング

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.
