Familiar with how to handle a 24v dc load with a 12v dc switch and relay, however I'm trying to do the opposite and struggling to find an appropriate relay and wiring diagram to do so. We need a 24v dc input from an existing switch on heavy equipment to trigger a relay that will control on a 12v load. The constant + to the relay would be fed from a 24 to 12v converter. Could anyone here lend some advice?
