Yes you can use 15 amp switches. I am kind of opposite in that I would prefer #14 on these 15 amp switches. It seems to me that getting the screw torque just right on (standard grade) 15 amp switches is tough. It's easy to overtighten and strip out the screws or if it's not tight enough you can watch the screws turn (loosen) as you push the device back into the box. I think 20 amp rated switches are a better match for #12 awg wire.
