I've never seen a blue 4-way, nor have I seen a MICRO 4-way.
Your best bet is to get a blue leafswitch 8-way, and a red leafswitch 4-way, and then swap the sticks.
the only difference between the leafswitch sticks is the shape of the hole on the bodies.
The 8-way micros are the ones that use the square actuator.
It may be possible to swap the sticks between the micro and leaf sticks, but you'd have to ask someone that has both to be sure......PAIGE??
