A simple way to convert between conducting paths and switch settings is to use (electro-mechanical) relays.
What determines the switching speed of a relay network?
conducting path composed of switches closes circuit
current flowing through coil magnetizes core and causes normally closed (nc) contact to be pulled open
current flowing through coil magnetizes core and causes normally open (no) contact to be pulled closed
when no current flows, a spring in the contacts returns them to their normal positions
