How do I connect 2 Ethernet Printers and an Ethernet external data storage device (Drobo) to my iMac

I have a late 2017 iMac. It is connected via wifi to the internet. The internet router is in a central area of my house. So the iMac is no longer physically close to the internet hub. With my previous DSL internet, the router was adjacent to the computer and all my peripherals plugged in via ethernet connections to the router which then connected to the iMac. Now I have new cable internet but as mentioned the router is located physically far from the iMac and I can't run ethernet cables from the peripherals to the internet router.

My issue is that I have two ethernet printers ( a Canon and a Xerox colour) and a Drobo unit that I need to connect to the iMac - each use ethernet, but there is only one ethernet port on the iMac.

What sort of device can I use that will take all three ethernet inputs and allow me to connect that to the iMac? Will a Netgear 5port Megabit Ethernet Switch or TP-Link TL-SG1005D 5-Port Gigabit Desktop Switch - switch - 5 ports device work or is there some other way to do this?

Thanks.
