2x1 voltage switch?

I'm looking for a 2x1 (2 in, 1 out) switch controlled by 13/18 volt change from satellite receiver. I must switch between two satellite cables, and I can not use 22 KHz (it's used for band changing) neither diseqc because receiver has no diseqc function. So the only solution is using a 13/18 volt switch. I know this is a very strange situation.... it's a professional system. If I don't find a similar switch, I must use a manual one but it's not so usage. Any idea where to find it? Surely I saw one in the good analogue era, but it was many years ago.

I found this product:

It's not a 2x1 switch, it's a larger 3x8, but it includes a terrestrial option (that's a good news). I believe this could solve my problem, what do you think?
