Correct.  Most of them use a round hole and an indexing hole or two to keep the button properly aligned.



There are some buttons that snap into a square/rectangular hole in a metal panel or maybe you want to make holes for carriage bolts.  There are many ways you can handle these situations.
- Drill a round hole and file to the corners.  It's low tech and labor intensive, but it is the el-cheapo way using commonly available tools.
- Square metal punch.

- Square broach.

- Specialized eccentric bit. (see animation at 1:15)


If you want to make square holes in wood, there are punches for use with hammers and hand drills . . .

. . . and similar chisel/bit combinations for use with drill presses.

Lol think i messed up my measurements. Im gonna need smaller buttons, 30mm hole gonna be too big since screen is recessed so didnt take that into. 15mm hole should be doable. Do they make buttons for that size? Need 4 buttons.

Not in arcade buttons.  Smallest ones that I would consider real arcade buttons are 24mm Semitsu or Sanwa.

Ond:
Getting the best tools you can afford for any job is good advice, BUT, expensive tools are not what determines craftsmanship.  I've seen workshops full of expensive tools and nary a craftsman in sight.  I use spade bits for drilling most holes using a drill press.  Not expensive.  Holes come out clean every time.

slybunda:
Drill press is the key word there.

Need to find smaller buttons for admin function use. Will have to hunt around.
