CD4016 have four bilateral (on/off) switches. OP asked for "switch between two signals", 2:1 SPDT.

You can build a SPDT switch from two 4016 switches if the control signal is also available in inverted form. The remaining switches in the 4016 can be used as an inverter.

Yes. These switches can be used as general purpose logic elements. They can be connected in series and parallel to get AND and OR functions.
