Introduction
If you need a simple way to switch one Ethernet connection between two network devices, the RJ45 Splitter Selector Switch from SinLoon offers a compact and straightforward solution. Designed as a 2-port network switch selector, this small metal box can operate in either a 2-in-1-out or 1-in-2-out configuration, depending on how your network equipment is connected. Its push-button design makes switching between connected Ethernet paths quick and convenient without requiring software, drivers, or a complicated network configuration.For users searching for a Dual Zone 10GbE network switch, there is an important specification to understand before purchasing: this SinLoon unit is rated for 100 Mbps Ethernet, so it should not be considered a genuine 10GbE switch. The keyword may be relevant to shoppers researching multi-zone network switching, but this particular product is intended for basic 10/100 Mbps Ethernet applications rather than 10 Gigabit networking.
This distinction actually makes the product easier to evaluate. Rather than paying for a more complicated managed or multi-gigabit switch when you only need to select between two Ethernet connections, this mini selector focuses on one basic job. It can be useful for home networking experiments, small office setups, testing equipment, older Ethernet devices, network troubleshooting, or situations where two Ethernet paths need to share one connection.
Features
Compact 2-Port Ethernet Selector
The central feature is the two-port RJ45 switching arrangement. Instead of installing a full network switch with multiple active ports, the SinLoon selector provides a physical method of choosing which Ethernet path is connected.The compact design can be particularly useful when desk space is limited. A small metal enclosure is easier to position beside a router, modem, computer, network appliance, test bench, or other Ethernet hardware.
2-in-1-Out or 1-in-2-Out Operation
One of the most useful aspects of this device is its flexible connection concept. Depending on the application, it can be used as a 2-in-1-out selector or a 1-in-2-out selector.In a 2-in-1-out configuration, two Ethernet sources can be connected and one selected connection can be routed onward. This can be useful when you want to manually choose between two network sources without repeatedly unplugging Ethernet cables.In a 1-in-2-out configuration, one Ethernet source can be connected to the selector while the user chooses between two connected destinations.This physical switching approach is easy to understand and does not require an application or network-management interface.
Push-Button Switching
The push-button mechanism is designed to make changing the selected Ethernet path simple. Instead of reaching behind equipment and disconnecting cables every time you want to change a connection, the selector allows the connection state to be changed using its physical control.That makes it practical for situations where equipment is frequently tested or where access to the rear of a computer or network device is inconvenient.
Metal Mini Switch Box
The metal enclosure gives the selector a more substantial construction than many lightweight plastic networking accessories. Its small form factor also makes it convenient for portable setups.For a technician, hobbyist, or home user, a compact physical selector can be easier to carry and deploy than a larger powered Ethernet switch.
No Complex Network Configuration
This is a hardware-based selector rather than a software-managed network device. That means there is no dashboard, IP address configuration, firmware interface, or management application to learn.The simplicity can be an advantage when the objective is simply to change the physical Ethernet path.However, users should understand that a passive or manually switched selector is not equivalent to an intelligent Ethernet switch. It does not provide advanced routing, VLAN management, traffic monitoring, link aggregation, or 10GbE switching features.
100 Mbps Ethernet Limitation
The product description identifies this model as a 100M Ethernet device. This is one of the most important specifications to consider.If your network infrastructure includes 2.5GbE, 5GbE, or 10GbE equipment, this selector should not be purchased with the expectation that it will preserve those higher speeds. A true 10GbE environment requires compatible cabling, network interfaces, and switching hardware designed for 10 Gigabit Ethernet.
For basic 100 Mbps Ethernet equipment, however, the speed limitation may not be an issue. Older computers, legacy network devices, certain testing setups, and basic Internet connections can still benefit from a simple physical Ethernet selector.
Pros & Cons
| Pros | Cons |
|---|---|
| Compact metal enclosure | Limited to 100 Mbps Ethernet |
| Simple push-button operation | Not a genuine 10GbE network switch |
| Supports 2-in-1-out or 1-in-2-out configurations | Does not provide advanced network management |
| No software or complicated configuration required | Not designed for multi-gigabit networking |
| Useful for basic Ethernet switching and testing | Two-port design limits scalability |
| Small footprint for desktop or equipment setups | Not a replacement for a powered Ethernet switch |
Performance
When evaluating the performance of this SinLoon RJ45 selector, the most important consideration is matching the device to the right networking environment. Its 100 Mbps specification places it firmly in the basic Ethernet category.For a simple setup involving compatible 10/100 Mbps devices, the selector can provide a convenient way to manually choose an Ethernet connection. Its physical switching mechanism avoids the overhead of software-based configuration and can be particularly convenient when connections need to be changed regularly.
For example, imagine a small workstation where one Ethernet cable needs to be used with two different devices at different times. Instead of repeatedly removing the RJ45 connector, the selector can provide a dedicated switching point. This can reduce cable handling and make the setup more organized.It can also have value in troubleshooting scenarios. A technician may need to compare two network sources or alternate between different Ethernet-connected devices. Having a physical selector on the desk can make those changes faster.Another potential use is a small demonstration or testing environment. Because the device is compact, it can remain connected between equipment without consuming the space required by a conventional network switch.However, expectations should remain realistic. The device does not turn a 100 Mbps Ethernet connection into a 10GbE connection. It also does not combine two Ethernet connections to create double bandwidth. The 2-in-1-out terminology refers to physical selection between connections, not link aggregation or bandwidth bonding.This is particularly important for anyone searching for a Dual Zone 10GbE network switch. If your objective is to build a true 10 Gigabit network with high-speed NAS storage, workstations, servers, or professional video-production equipment, a dedicated 10GbE switch is the appropriate category of hardware. This SinLoon product is better viewed as a compact 100 Mbps Ethernet selector.
The same distinction applies to network security and management features. Traditional managed switches can offer VLANs, QoS, monitoring, port configuration, and other advanced functions. This compact selector is designed around physical connectivity instead.For basic applications, that simplicity can be exactly what makes the product useful. There is less configuration to troubleshoot, fewer settings to manage, and no need for an additional power adapter simply to operate a physical selection mechanism, depending on the specific installation.
Who Should Consider This Ethernet Selector?
This product is best suited to users who have a specific need for simple Ethernet path selection rather than advanced network switching.It may be useful for:
- Home users with basic 10/100 Mbps Ethernet equipment
- Technicians testing different Ethernet connections
- Small workbench and laboratory networking setups
- Legacy networking equipment
- Temporary network configurations
- Users who frequently change between two Ethernet-connected devices
- Compact desktop networking installations
It is less suitable for users building modern high-speed networks around 2.5GbE, 5GbE, or 10GbE equipment. Those environments require networking hardware with matching speed capabilities.If your setup also includes video conferencing, webcams, or other workstation accessories, you may find our September 2026
