Power a 12VDC cooling fan using LEAST amount of space possible using a switch. This needs to fit in a small helmet.
I bought a 40MM 12VDC Cooling Fan (130mA 1.56W) from Raido Shack and I am trying to put it inside my modded Mark VI helmet from the Halo video game series. I bought a small Switch from Hobby Lobby (teamnovak.com Switch Harness #5600) and a 9V battery. I know the volts are off so I need to know what I need to do/buy to get this working. I connected the fan (+) to the switch (+) and those to the battery (+), then the fan (-) to the switch (-) and those to the battery (-) It worked just how I wanted but after about 60 seconds the battery got VERY VERY hot. I did my research and found that this outcome is normal but couldnt find out how to fix it. PS: I am new to this website ans suck at electrical stuff.
