A two-way analog switch is a CMOS IC that contains logic controlled switching of an isolated FET switch in the same package.

The type of IC that does this, is the CD4053, 4000 series logic device, and contains 3 in a 16 pin DIL package. For instance:- Applying a logic 1 to pin 10 would close the analogue switch between pins 1 & 15, this would be wired to a separate circuit, but there are limitations on the voltages and currents that can be applied to these switches, and you would have to consult the datasheet to find this out.
