Hi, I'm wondering what I can use as a voltage-controlled four-way selector switch. It should be fairly simple, because I need to use a large number of them, and it should be able to source and sink a little but of current (at least 50mA).
I know there are ICs called analog switches, but I can't find a good explaination of how they work. Do they act like a short when closed, or is there a significant resistance? Do they come in anything besides SPST?
Thanks
