This is the switch for a cross-blade. It comes with RGB-X Ecoswing electronics with THREE RGB LED units, so long as you purchase 3 emitters of your choosing, a grip, and a pommel! You will also most likely want to add a standard blade for your main blade, and a pair of the 5" cross blades.
Also note, no other upgrades, such as neopixel can be applied to this.
