Well after spending some time going through the manual, I did not see a section detailing how to pull apart the switch.
My suggestion would be to get a new Honda switch, save it and try to pull the old one apart.
If you can fix the old one, great but if that worn, it might fail soon anyways so you would want the new one.
I think honda still makes them.
The ride IS the adventure. The destination is just to get gas!
