Trying to find an electronic single-pole multiple-throw switch
You'll need to design a relatively uncomplicated circuit to achieve your goals.
It'll consist of 2 parts. The 'electronic switches' themselves and the interface to the rest of your design whether analog or digital.
I'd consider using either jfet's for the switches or analog transmission gates such as the widely used CD4016, 4051 or 4066 from the inexpensive CD4000 series or maybe something that can deal with a higher voltage range such as Siliconix's DG211, 308 etc..
The use of discrete jfet's is only really warranted when you need to preserve signal integrity to a large degree. For most applications an IC switch works well.
It's then a simple matter to 'decode' your switch selection input to a suitable format to drive the switches.
