Just saw this on E-Bay. Should work for any fly by wire Spyder RS ST or RT.
Don't know about the F3.

Just remove the Cruise portion of the switch from this one and install it in place of the non Cruise portion on your present switch.
OR, you do it the hard way and replace your entire right hand non cruise switch assembly with this one.

I have NO financial interest in this sale.
