Network Switches

Network switches are essential components in modern networking infrastructure. Unlike simple hubs, a network switch intelligently directs data packets between connected devices such as computers, printers, and servers. Whether you're setting up a home office, managing an enterprise network, or upgrading industrial communications, choosing the right Ethernet switch ensures efficient, secure, and uninterrupted data flow.

At RS Singapore, we carry a broad range of network switches, including PoE network switches, industrial Ethernet switches, and RJ45 switches, all designed to meet your connectivity needs. For more detailed information, visit our network switches guide.

What Is the Difference Between a Network Switch and a Hub?

Although network switches and hubs serve similar roles, they differ significantly in function:

Hub: Broadcasts all incoming data packets to every device on the network, regardless of recipient. This indiscriminate data input can cause unnecessary traffic congestion and reduced network performance as all devices process all packets.
Network Switch: Inspects incoming data packets to determine their destination and forwards them only to the intended device. This targeted delivery reduces network congestion, enhances data transfer speeds, lowers latency, improves bandwidth efficiency, and provides better security by limiting broadcast domains.

For these reasons, network switches are preferred over hubs in business, industrial, and even most home networks.

Types of Network Switches

When selecting a network switch, it’s important to understand the types available and what each offers in terms of control, flexibility, and performance.

Managed Switches

Managed switches provide advanced network control, including Virtual LANs (VLAN) configuration, Quality of Service (QoS), port mirroring, traffic prioritisation, link aggregation, and diagnostic monitoring. These are ideal for larger corporate or industrial setups where network segmentation and monitoring are critical.

Unmanaged Switches

Plug-and-play simplicity defines unmanaged switches. They offer basic connectivity without the need for setup, making them a reliable choice for home networks or small offices with minimal IT support.

LAN / Active Hubs

These hybrid devices serve as simplified switches, capable of controlling data distribution based on real-time network demands. They're suitable for legacy systems or where limited traffic management is sufficient.

PoE Network Switches

A PoE (Power over Ethernet) network switch allows both data and electrical power to be transmitted over a single Ethernet cable. This is especially useful for powering IP cameras, VoIP phones, and Wi-Fi network switches in places where running separate power lines is inconvenient.

Understanding Key Technical Features

To select the best switch, consider:

Port Count and Speed: Switches range from a few ports (4-8) to 48 or more, with speeds including Fast Ethernet (10/100 Mbps), Gigabit Ethernet (1 Gbps), and multi-gigabit options. Match port numbers and speeds to your current and future network demands.
Layer 2 vs. Layer 3: Layer 2 switches handle device-to-device communications within the same network segment, while Layer 3 switches add routing capabilities between different IP subnets, enhancing network segmentation and traffic management.
Management Interface: Managed switches offer web GUIs, CLI access, or SNMP for configuration and monitoring. Consider your IT team’s expertise the desired level of network control, as unmanaged switches offer plug-and-play simplicity without advanced configuration options.
PoE Standards: Check PoE standards supported (IEEE 802.3af, 802.3at/PoE+, or 802.3bt/PoE++) for power delivery capabilities matching your devices’ requirements.
Redundancy and Reliability: Features like link aggregation, redundant power supplies, and ring network protocols increase uptime in critical applications. These features minimize single points of failure, ensuring network continuity and high availability for essential services and uninterrupted operations.
Security Features: Access control lists (ACLs), port security, DHCP snooping, and 802.1X authentication protect your network from unauthorised access.
VLAN Support: Virtual LAN (VLAN) support enables logical network segmentation, enhancing security, isolating traffic, and improving overall traffic management for different user groups or departments*.*

Industrial Applications of Network Switches

Network switches are widely deployed across sectors for reliable and high-speed connectivity.

Industrial and Manufacturing

Industrial network switches are designed for durability and performance in harsh environments. Used in automation systems, production lines, and monitoring equipment, these industrial Ethernet switches withstand vibration, temperature extremes, and electromagnetic interference.

Corporate and Enterprise Networks

In enterprise environments, managed network switches form the backbone of LAN infrastructure, supporting everything from file sharing to cloud access. Ethernet switches enable smooth data transmission between departments and ensure seamless communication.

Healthcare Facilities

Hospitals and clinics use network switches to manage sensitive data transmission across medical devices, imaging systems, and electronic health records. Secure, low-latency connections are vital for timely patient care and diagnostics.

Education and Campus Networks

Schools, colleges, and universities depend on network switches for high-bandwidth applications such as virtual learning platforms, security systems, and internal resource sharing. PoE switches are often used to power wireless access points and surveillance cameras throughout campuses.
