12V Electric Fan Setup

What amp power toggle switch do I need to use between my toggle switch and my ign/acc 20 amp fuse box connection?

The relay is setup with a 30 amp, but I presume my toggle switch would have to be a 20 amp back to the ing/acc fuse box!

See Attachment for configuration.

the load on the switch is only the relay coil
less than 1 amp
any switch will work though i would add a 1 amp fuse in the line

personally i wouldn't use a switch as the only means of turning on a fan
add a thermal switch in the circuit
to toggle the fan off and on when the thermal switch calls for it

Thanks! Yea, this is a temp setup and I do intend to add a temperature sensor to the configuration (eliminating the toggle as suggested).

So the 1 amp in-line fuse you recommend would go between the toggle switch and the ing/acc fuse box connection, right?
