You need to use a relay as well as the toggle switch. Let the toggle switch activate a relay to cut your fan on and off. This way you will not be burning your toggle switch out all the time and may prevent a fire hazzard as well.

i agree with henry, use a bosch relay. you can wire it directly to battery power (with an inline fuse/circuit breaker) and use your toggle switch to ground the relay to turn it on. i don't have a wiring diagram in front of me but i can look it up tomorrow. the bosch relays have a standard 4 blade terminal hookup that is easy to wire and the fan load goes through the relay, not the switch.

Single pole ,single throw , or double pole double throw , or single pole , double throw?????
There are a LOT of "toggle switches" out there.. what are you hooking up?
I'd go with the relay and forgo a "switch". What if you shut your car off , but it still needs to cool ? I hear electric fans kick on in cars that are parked , so I imagine it is necessary.
Good luck with your project.

Take a look at these diagrams using relays.
