I’ve come to the conclusion that external dome bump switches are a bad idea, for events at least.
I like the convenience of being able to quickly turn off the dome lights to save the battery, but kids quickly work out what they do and are constantly playing with them. They can’t do much damage but i’s very annoying, and I’m leaning toward replacing them with an internal switch even though it’ll be a pain to get at. I’m not sure if I’d leave the dead switches in place or replace them with simple bumps.
If you’re about to go down this route I’d personally recommend against having external switches of any kind.
