Vent/Heater switch

I'm installing a NuTone combination light/vent/heater in a bathroom reno. The installation procedure specifies 12 ga wiring but doesn't specify the amperage. The spec sheet says the total power consumption for the unit is 1770 watts.
I provided a new 20 amp circuit for the heater/vent and started to install the wall switches provided with the assembly. I noticed that all 4 of the switches are rated 15 amp.
Is this allowed by the NEC?

The circuit for the bathroom needs to be 20 amp, as you have done, with 12 gage wiring.

It is okay that the switches are rated for only 15 amps, as none of the individual loads exceed that.

I'd try to find a 20A switch for that particular circumstance.

Why?

The poster has indicated that the switches were provided with the assembly and that they are rated for 15 amps. The total amperage of the entire device is less than 15 amps and thr NEC clearly allows these switches.

It certainly won't hurt to use higher rated switches, but I see no reason to.
