Choosing an industrial Ethernet switch for a control panel or fieldbus backbone usually comes down to how many devices you need to connect, how rugged the environment is, and how much you want to spend. The four listed options here range from $27.99 to $159.99, so it's easy to overpay for ports you won't use or undershoot the ruggedness your floor requires. A good match will come down to your specific panel layout and network size.
Quick take
- Plug-and-play pick: The PUSR 8-Port Gigabit Ethernet Switch is an unmanaged option that supports wide-temperature operation.
- SFP uplink pick: The Industrial 6P DIN-Rail Ethernet Switch with SFP adds an SFP slot for fiber connections.
- Used N-TRON pick: The N-TRON 708TX Industrial Ethernet Switch is a used unit aimed at PLC and HMI networking.
- Open-box N-TRON pick: The N-TRON 708TX 8-Port is the higher-priced open-box option.

Product notes
PUSR 8-Port Gigabit Ethernet Switch

The PUSR option is the least expensive here at $27.99. It's an unmanaged switch with an aluminum housing, IP40 protection, and a wide operating temperature range of -40°C to 85°C. The dual-power input range of DC 9.6-60V fits panels where incoming power is not stable. Its mount is designed for standard control cabinets. The unmanaged nature means there is no per-port configuration, so it's best for straightforward plug-and-play Ethernet connections. If you need a no-setup industrial switch, this is the price anchor of the group.
Industrial 6P DIN-Rail Ethernet Switch with SFP

At $29.99, this switch is close to the low end of the price range. It's described as a compact unit with an SFP port, so you can add a fiber uplink in addition to copper Ethernet ports. Its switching capacity is 12Gbps, and the enclosure carries IP40 protection with 6KV lightning resistance. It also supports DIN-rail and wall mounting, which is useful in crowded control boxes. It is a managed switch, so it offers configuration options beyond the PUSR. The main trade-off is that the brand is not identified, so you are relying on the stated specs rather than a brand name you already know.
N-TRON 708TX Industrial Ethernet Switch (Used)

This used N-TRON 708TX is described as a rugged switch for industrial automation and motion control, and the product description says it is designed for PLC and HMI communication. At $34.99, it's the second-lowest price in this comparison. If you want N-TRON hardware without the higher price of the open-box unit, this is the direct route. The used condition is the trade-off: it is not listed as new or open box, so it carries more uncertainty than a fresh unit. For a no-frills N-TRON switch in a control network, it keeps the cost down while staying with the same model family.
N-TRON 708TX 8-Port (New Open Box)

This is the highest-priced option at $159.99. It's a new open-box N-TRON 708TX with a 10-30VDC input range. It includes the Ethernet/IP communication standard, which is useful for industrial networks that use that protocol, and the product description says it is designed for factory automation and control environments. The open-box condition means it's not sealed-new, but it is not used either. The price is higher than every other option here, so it makes sense when you need the open-box N-TRON 708TX spec and Ethernet/IP compatibility rather than a cheaper alternative.
Final recommendation
For a simple gigabit install, the PUSR switch offers the lowest price in the group and a ready-to-run package. For a more compact control panel, the Industrial 6P switch is the space-saving option. If you're already standardized on N-TRON hardware, the used 708TX gives you that model at a lower price, while the N-TRON 708TX 8-Port is the choice when you need the higher-priced option. Line up the key specs with your panel requirements before you commit.
