im a making a golf ball washer, which requires a heavy duty motor and windscreen washer pump to be powered off 12v. i am connecting two sets of 6v battery holders, using 1.5 cells. I want the motor and pump to be powered off of the same ptm switch, so that the motor rotates the brushes and water is squirted saimulatneously. is this a simple procedure? what would the circuit diagram look like?
