How is the simplest BJT configuration for performing a single pole double throw switch?

 

[danadak]

Draw the complete circuit (minus the SPDT solution) as to how its used ?

You looking to implement a 2 in 1 out logic level mux, or an analog mux ?

What is the physical layer attributes of your SPDT switch ?

All analog and/or logic signals must be defined a priori asking this question.
Also: input, output or bidirectional or just complementary?
