Hey, so, I wasn't the one who did all the electronics in this gauntlet, it was my son, and this is what he told me.
He told me that he didn't wire any switches into his circuit, he bought a pack of 9V battery packs off of Amazon, link here:

They have a
built-in switch, and he doesn't know what kind it is, he used these because it just made making the gauntlet easier.
Some other info he said was that the resistors he used were
220 Ohms 5%, Red, Red, Brown, Gold bands.
He said he wired it in
parallel if that means anything to you, and he said it was so that it was easier to wire into different areas, and if one solder job was bad, the rest still worked.
Hope that this helped, and if there is anything else, just let me know!
