My son built an childrens electric car which runs off a 48V system however when he wired it up he had 48v going through the ignition switch, needless to say it didnt last long before arcing / melting destroyed it, so i said it needs stepping down to 12V for the ignition switch and that couild then be used to energise a relay which will do the 48V switching ?? having only a limited knowledge of electrics does this sound a reasonable soluition to the problem ? how do I step it down ? simple resistor or what ? and is the relay the correct solution ? electronics gurus please advise
