If it's one of these Durite switches, rated at 29A, that'll do fine ?
What the diagram shows is that with the switch in position I, terminals "+" and "2" are connected, and in position II, terminals "+" and "3" are connected, so you want your power going to terminal "+", and the outputs to the heater fan from terminals "2" and "3".
