Thank you for your help

How do you get carbon arcs on a low voltage door chime board?


The carbon builds up then it arcs across. If you are thinking that low
voltage will not arc, you are mistaken. Take a 9volt battery and put steel
wool across both contacts. It will cause a fire. My kids use to love doing
this at the kitchen table when they were young.
