Is there an rca input selector box audio only 2ch in 1 out?

I searched yesterday and could not find this but I thought someone might know if there is such a box that could have 2 channels (2 pairs rca) incoming and one out put so I could switch between phono and sacd player to analog input.My new amp only has one analog input and just looking to leave cables in place instead of unplugging all the time.I really googled but found video switches. I found a tube line buffer but it only has one channel input. thanks for any help.
