need help in designing switching circuit for amplifier

[PYGuj]

hello! is it possible to use a single amplifier circuit to amplify signals from two different wheatstone bridges through any switching circuit?

What controls the switching circuit? Why can't you use a mechanical switch?

i am expected to use sort of an analog mux circuit to switch between the two. any idea how i can do that with a 4051 mux? i don't know much about how to set the time intervals when the mux circuit reads between the two.

I could not see the break before make switching delay time for a CD4051 on its datasheet. Circuits with it usually bias the output at half the analog supply voltage so during the delay time the signal goes half-way.

Is there any way i can implement the switching circuit with another IC please? if possible a schematic diagram will be very helpful. Thanks!
