I'm looking for something (IC, small circuit) like a switch or transistor, which can be controlled by a digital, analog or any other kind of signal. I want to connect a few of these to the signal output and depending on the signal the "switches" turn on or off.
It is a very abstract idea and I have no clue how to archive that. The solution should be small and cheap.
