研究ノート
1. What this is
Kailh Speed Pro Light Green 50g Clicky Plate Mount Switch is a mechanical keyboard switch from Kailh. It is clicky, 50g, 3-pin (plate mount).
2. Spec decode (from product name)
- Switch type: clicky
- Actuation force: 50g
- Mount: 3-pin (plate mount)
3. Compatibility & use
Standard MX-style keyboard switch. Choose by feel (linear/tactile/clicky), actuation force, and sound (silent vs standard); this is a 3-pin plate-mount switch (needs a plate). Hot-swap or solder depending on your board.
4. Data-quality note
The switch type, force, and/or mount are decoded from the product name (the standard way keyboard switches are specified). Confirm exact spring curve, travel, and housing/stem material against the manufacturer's spec if precision matters. (Note: some of these rows are catalogued under a generic push-button/arcade-button category in the source data; the correct device class is keyboard switch, recorded in the specs above.)

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.
