MZTC344A: Share One Keyboard Between Two PCs With One Button

The MZTC344A is a USB switch with two inputs and four outputs: share one keyboard and mouse between two PCs with a single button press, no recabling ever.

Two computers, one desk, and one set of controls you actually like: the keyboard you know, the mouse that fits, the printer that works. Getting all of them onto the second machine has always meant the same clumsy ritual, reaching behind the monitors, swapping cables, waiting for the system to notice. The MZTC344A, the newest switch in the Mattzon KVM switch line, turns that ritual into a single button press.

Two Inputs, Four Outputs, One Button


The specification, straight from the product page: a USB 2.0 switch with two USB inputs and four USB outputs. Plug the keyboard, mouse and two more peripherals into the outputs; run the inputs to two computers; and switch the whole set between them with one button, no recabling, no re-pairing, no unplugging anything. The product page names the settings it fits best: office work, classrooms and server rooms.

Why USB 2.0, in a 10Gbps world? Because this switch is honest about its job. Keyboards, mice, printers, scanners and control interfaces are low-bandwidth devices by nature, and USB 2.0's 480Mbps carries every one of them with headroom to spare. What they need is not speed but stable, instant, reliable switching, and that is what the MZTC344A is engineered to deliver, at a price point that makes one per desk reasonable.

The Hidden Return: Your Ports Live Longer


The efficiency gain is obvious; the hardware gain is quieter. Every swap ritual is a plug-in cycle, and plug-in cycles are what wear out connectors: the latch loosens, the contacts scrape, and one day the port that held firm develops the intermittent faults that fill troubleshooting forums. A switch installs those cables once, seats them properly and leaves them alone. Fewer plug cycles, longer connector life, fewer mystery disconnections, the same reliability logic we apply across the Mattzon switch line, where every unit passes per-port functional testing and an aging test before shipment.

Offices, Classrooms, Server Rooms


The settings on the product page are chosen with care. Offices run a work laptop and a personal machine on one desk set. Classrooms alternate between the instructor's machine and the demonstration unit without re-cabling in front of a class. Server rooms share a console keyboard between machines where monitors and inputs are at a premium, and a physical button is a feature, not a compromise: it works even when the network does not.

For distributors and brand buyers, the MZTC344A comes from our own Shenzhen factory with the standard Mattzon terms: 89% private-mold products, OEM and ODM service welcome, no minimum order quantity, samples for evaluation and 3 to 25 day lead times. As a companion to the MZTC344D DisplayPort switch, it lets a buyer build a complete switching story: displays on one SKU, peripherals on the other.
