ACE 737 Yoke - How To Remove Trim Switch?

Hello,
I have an ACE 737 Yoke (www.737yoke.com), and unfortunately they have not responded to my emails (I can't find guidance on this forum, either). I need to remove the trim switch from the right side of the yoke, so that I can move it to the left side.

I cannot determine what is fastening the trim switch into the yoke body. There is some type of hole on the side of the yoke, shown in the photo, but I don't know if it's related. Can anyone shed some light as to how the trim switch is removed? Thank you!
