You can try these analog switches CD4066. Its main application is to multiplex or demultiplex analog signals. They are pretty easy to use, just like normal switches but they have a control pin to make it close (lot alike a relay...)
Check its data sheet at: hxxp://www.fairchildsemi.com/ds/CD/CD4066BC.pdf
Another option is to use CD4051 (part of it) or CD4052 (1/2 of it - see picture below) ..
It is almost like having CD4066 CMOS switches with some additional logic ..
