Hello my friend

This is my first time building a plane, being a Pilot Rc Extra 330 SC with a DLE 35RA. i have been advancing very well, but i have spome doubts o how to install the switches. My plane have supposedly the switches holes already prepared but after cutting the monocote on the switch area i noticed the switch is significantly smaller than the hole provided!

Any recommendation on how to fix this?

Thx in advance!
