Trunk mounted battery

Its been years since I read a NHRA rule book but if my memory serves me correctly the handle, paddle, flipper dodad... whatever you want to call it, cannot be made of plastic or be of the removable type ie slide in to engage the switch. As stated it is a safety device. Track personnel have to be able to quickly identify the switch and deactivate the cars electrical system in the event of an accident/incident. Make sure the switch you choose can handle the continuous amp output of your alt. There are a lot of low amp rated switches on the market.
