Why the transistor acts like switch during saturation mode?

An ideal switch is zero ohms when on and infinite ohms when off. A transistor in saturation is a few ohms, and in cutoff it is many millions of ohms, so it can be a fairly good switch. Active mode, it has a resistance that varies all over the place, and that is not useful in a switch. .
