Multi function switch question

I am going to connect a new bathroom fan that has a light, night light, and fan. I also have a separate vanity light in this restroom. I'd like to connect all functionality to a 4 function rocker switch. Links for the fan and the switch are below.

As you can see, the two 2-position rocker switches are rated for 15 Amps and the 3-position rocker switch is rated at 5 Amps.

Fan: 33.5W
Fan Light: two 18W CFL bulbs = 36W
Night Light: 5W
Vanity light: two 60W bulbs - 120W

I'd like to connect like this:
night light & fan light on the 3-position rocker
Fan on 2-position rocker
Vanity light on other 2-position rocker


Is it ok to wire the fan light and the night light to the 3-position rocker? With two 18W bulbs I calculate the amperage to be around .33 amps on 110V, so well below the 5 Amps rating.

How would I add in the wiring for the vanity light? My best guess:

The 5W night light would connect to the top left red lead
The 36W fan light would connect to the top right blue lead
The 120W vanity light would connect to the left middle screw terminal
The 33.5W fan would connect to the bottom left screw terminal
The power line in from the house would connect to the only screw terminal on the right of the switch

Thanks for your help!

That's using only 3 positions. Did I miss something? Or is the night light/fan light considered two positions?

You won't have any problem with your connection of this switch for these loads. Difficult to tell which screw would be best for the three position switch. It would be a personal preference for your use. If it turns out to be inconvenient, you can always change the configuration of the night light and fan light later to suit your needs.

Yes, on the 3-position rocker it would be: left position=night light, middle position=off, right position=the brighter fan light.

I did some more thinking on it after posting and I'm 100% certain that the red and blue lead correspond to the 3-position rocker and the screws line up with the remaining 2-position rocker switches. So yeah, the two screws are the 15-amp terminals and the red/blue leads are the 5-Amp terminals. So it would be:

red=night light
blue=fan light
middle screw=fan or vanity light, my choice
bottom screw=fan or vanity light, my choice
