can I use this magnetic switch to open and close rv steps

I would advise using these to operate a power relay. The contacts in the reed switch are delicate, by using the reed switch to open and close a HD relay, the relay could then operate a hydraulic system, light duty, to raise and lower your steps. Seek help from an electrician, to design a suitable circuit. W.

What size wire should I use?

18 gauge 2 wire [18/2] or 22 gauge 2 wire [22/2] security alarm cable works best.

Porque se calienta el interruptor magnético ???

Es normal que tenga una temperatura que no exceda mucho siempre que esté. Respetando el amperaje de la capacidad de los switch. Eso kiere decir que ocupa poner luces led y es recomendable no conectar muchas luces en un solo switch

It's a roll up garage door?

it MIGHT work, but I would not recommend this set for a rough environment like a garage. Instead find one like https://www.amazon.com/Honeywell-Ademco-Overhead-Door-Contacts/dp/B0006M1I1W/ref=sr_1_4?ie=UTF8&qid=1518396534&sr=8-4&keywords=garage+door+alarm+sensor Honeywell is a good brand for sensors and panels.
