How to Connect Apple router via lan to A Switch

Hi everybody.

I have this scenario. I need someone can make this happen. (all setup is over LAN)

I would like to connect my Modem to a Switch with 24 port (via LAN). Then I want to connect my Apple Routers (Express, Extreme) to that Switch (via LAN) so I can extend my WiFi in each (floor, room, place) and make hot spots.

No extending over WiFi. No connection from - Modem > Apple Router > (3-4) ports only.

Maybe - Router > Apple Router > Switch > 24 Apple Routers.

Thanks guys. I really appreciate the help.
