Its a 4 position paddle switch with 3 pickoffs on the resistor that is on the back of the switch beside a fuse holder. OFF-LOW-MED-HIGH.
If the motor amperage is 2 amps, if the battery voltage is 6v, that's 12 watts. If it's 12v, it's 24 watts. (P=IE) They get hotter than blazes with a 12v input. I have 5 of them and all have very badly cracked and discolored resistors and blown fuses. I would just like to get a 3-pickoff resistor that is rated for 12 volts. I have not been successful yet.
