Actually many quote DC rating and non-inductive AC rating.

Many the non-inductive AC current rating is x2 to x3. The non-inductive=20
AC rating is typically close to maximum current with not operating switch.

A FET seems a better idea as even a 15A static current switch, doing 1A=20
switching is quite large.
