But in general, diodes can be (and are) used as controlled AC switches.
One good example are the head select diodes in disk drives. You apply a
direct voltage and thus "open" the diode. You then have a overlayed
alternating voltage coming from the head coils passing through the diodes.
This is then AC coupled to the preamplifier.
