Will an A/B switch work in reverse?

I have a single coax line running into my motorhome, which is usually used for satellite. Occasionally, when in an RV park with cable, I will hook up to that rather than setting up the satellite, but then I have to transfer the coax from the Satellite In connection on my control box to the Cable In connection. Can I use an A/B switch in reverse--i.e., a single coax in and two out, one to satellite and one to cable, throwing the switch depending on which I want to use? Thanks in advance.
