ActivoCherry MX Blue Clicky Keyswitch
Cherry MX Blue — tactile clicky keyswitch.
Aplicaciones comunes
The classic clicky switch. Audible click and tactile bump at actuation point. Popular for typing-focused keyboards and transcription stations. The click mechanism inspired countless clones after the patent expired.
Advertencia de falsificación High riesgo
Same counterfeit risk as all Cherry MX. Blue is especially counterfeited due to its popularity. The click mechanism on genuine Cherry is precise and consistent — fakes often have mushy or inconsistent clicks.

Mounting Type
How the button attaches to the panel. Panel mount is standard — installs through a cutout from the front.
|
PCB mount / plate mount

Referencia rápida de instalación
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.

Solución de problemas
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.
