Research Notes

1. What this is

Akko Crystal Pro 45g Linear Plate Mount Switch 45 Pack is a mechanical keyboard switch from Akko. It is linear, 45g, 3-pin (plate mount).

2. Spec decode (from product name)

Switch type: linear
Actuation force: 45g
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.)

Installation Quick Reference

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.

Troubleshooting

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.
