Yesterday, while choosing model on my Spektrum DX6i, the rolling switch broke.

its snaps are attached. Please advice

a) If its spare is available?
b) Do someone have this spare?
c) Can this be repaired ?

 Hope this helps

Just make sure when you press the roller, you press it at the top of the roller. Not in the center of the roller. And just press it hard enough just to make it click. Not to hard.be gentle.
