Wholesales Authentic SMD RGB Cherry mx Switch 3 pin Mechanical Keyboard Speed Silver Silent red Blue Pink Switches Red 3 pin 68 pcs

This link is only the shaft and switches for mechanical keyboard,no keyboard and switch tester included..
Pls note: This switches can only be used with smd led PCB keyboard,such as GK61 GK64 mechanical edition..
This switch can't replace with optical switches.It can't replace with the keyboard whose 2 pin 4 pin switch leds.It can only use with SMD leds PCB.
2 pin 4 pin switch led can't be used directly with this switches,such as 2x3x4 and 3mm and 1.8mm leds.
SMD switches uses together with SMD RGB PCB,the effect is much better than normal switches.
