Not that it matters in this case as current to be switched is probably extremely low.
But for sake of accuracy and interest, the design and ratings of ac and DC switches are quite different. When a switch interrupts a circuit, it has to deal with arcing across the contacts. With a.c. there is a voltage zero 100 times every second on a 50 Hz system, so the arcing is easier to extinguish. Contact gaps on an a.c. switch are usually quite small (micro gaps) and are often operated by a simple rocking device (e.g. like your light switch at home) for that reason.
However, DC voltage is constant and when interrupted will tend to arc until the contact gap is large enough for the arcing to collapse. That’s why DC switches tend to be toggle type or snap action with much larger contact gaps and a speedier separation.
.So if you use an a.c. switch on a DC circuit, the amperage rating will be considerably reduced from what was quoted for a.c. use.
As I said above, the switching duty in this case is merely a gnat’s whisker anyway.
