TRENDnet 5-Port Hardened Industrial Gigabit DIN-Rail Switch,TI-G50, 10 Gbps Switching Capacity, IP30 Rated Gigabit Network Switch (-40 to 167 ºF), DIN-Rail & Wall Mounts Included, Lifetime Protection 5 Port Switch

Cost a more than other products but these seem very durable in field applications

Works well in the heat. These are being used in control boxes that sit out in the sun and heat. There have been no failures so far after two years.

I selected this switch for three reasons: At least 5 x GB ports Industrial device so I can potentially connect my 12V or 48V battery directly but really I wanted POE to power the device via LAN cable. Turns out the advertised device does NOT have PoE, which I could have found out had I mistrusted the description and checked on the OEMs site. Misleading description. Price and industrial design is good.

Installed two of the four switches I purchased and so far they are working as expected. Will be installing the other two in the coming weeks and don't expect any issues.

Looks great and works great in an industrial electrical cabinet, and runs on a really wide voltage range, PLUS has a very reasonable current draw. I like this switch and will buy more when the time comes, provided it keeps performing.
