If you want a truly proffesional button, that can also be serviced by popping a new microswitch on the rear, or replacing a single part, look at the coin-op amusement offerings.
Large, small, lit, glow in the dark, I near any color, you name it, they make it. They have deep ones too, a 2" depth should be out there. The pinball flipper and cabinet video game buttons are designed for severe abuse, safety, and easy maintenance. A single big hole near 1"(? I forget how big) and you're likely done with the drill.
The actual switch pops into a plastic bracket on the rear with one hand, and because the switch is separate, the voltage/amperage of it can be taylored to suit the need, and most switch Mfg brands will fit it.. Also a bonus, many times the parts fit other brands of buttons too. They are considered to be "universal". The lighted 3" square one and pinball flipper type, usually fit the same hole.
They also have clear versions that hold labels, and escutcheon plates to protect the cabinet around the button, which also hold labels sometimes.
In bulk, even small bulk, the price often drops rapidly.(note which, if any, switch is included with the buttons, mention getting both too, if you have a non-profit behind you, etc.) My "best price" references would be outdated.
Initial cost might be more, but the long term economics of the system around public abuse is well proven.
Working on coin-op, I saw kids break the indestructible. The amazements too long to list. I still can't figure out some of it. Short of antigravity fields, soda being on a down facing mother board in an inaccessible area inside a cabinet can't happen, but did. I saw layered welds get broke that would have worked on a semi truck frame... Amazing stuff!)
With lots of kids around, these buttons might be worth it to you long term
So might a wire cover on the backside..... Hide the screwdrivers .
Forget that...Hide everything, watch for group attacks, and destraction tactics, lol.
