Is the hole for on off button? I want to add a voltage meter to my razor electric scooter so I can monitor the battery usage and charging voltage but need to be able to turn off as it will be link directly to battery all the time. Just wonder how you did yours

How do you attach the botton button? do you just glue the botton by tue hole?

hot glue actually

yes the hole is for a button actually i used a momentary switch as you see (black dot in the hole), it stays off normally, when i press it, it will turn the meter on and i can read the values, if you need switch like mine here is the link https://de.aliexpress.com/item/32838807664.html?spm=a2g0s.9042311.0.0.27424c4dYOze7m

Wow that is a lot of buttons for the price, haha Thanks for the advice for the hot glue
