I am looking for about 10-15 buzzers for an electronic logic board
lesson for my grade 9 kids. Does anyone know of an inexpensive source
for these? Thanks

Thanks for that, I am also trying to find larger lots - like 20.
I hope the ones I have seen are the right ones for the project:

I just want a noise like when someone gets an answer wrong in a game
show, when student pick the wrong answer.

Sorry, they are just going to be working with Button batteries C2016
3V probably doubled up for 6V. Those links are great, thank you for
that!
