CAT6 A/B Network Switch

The Black Box Corporation SW1040A is a CAT6 A/B network switch that uses latching relays to route a single RJ45 link between two ports. It operates at Layer 1 so the signal passes through without buffering or protocol interpretation. Remote control is provided through a dry-contact interface for integration with external automation systems.

Suited for Physical-Layer Path Switching

This unit suits installations that must alternate a CAT6 connection between two endpoints while preserving the physical-layer characteristics of the cable. It does not serve networks that require managed switching features such as VLANs, QoS or SNMP monitoring, and it cannot aggregate or load-balance traffic across the two ports.

Dry-Contact Remote Control

The decisive specification is the dry-contact remote control input that lets an external relay or building-management system trigger the A/B changeover without applying voltage to the switch itself. This allows the SW1040A to be driven from control panels, timers or environmental sensors in industrial and broadcast environments.

Questions about this item

Will the latching relay contacts on the SW1040A need periodic replacement after many switching cycles?

The latching relay holds its position without continuous power, so the mechanical contacts are rated for a long service life and typically do not require scheduled replacement under normal use.

What limits how many times the CAT6 A/B paths can be switched per day on this unit?

The switching speed is constrained by the relay actuation time; the datasheet specifies a maximum of 45 operations per minute to maintain reliable contact closure.

Does the SW1040A generate noticeable heat or fan noise when left powered and switching continuously?

The unit has no internal fan and draws minimal power in its latched state, so it runs silently with negligible temperature rise even during all‑day operation.
