The Logitech multiple device keyboard and mouse is a wireless input set that connects to up to three devices simultaneously and switches between them with a single button press. It uses Logitech's proprietary Easy-Switch technology to enable smooth control across computers, tablets, and smartphones without needing to reconnect.
This setup is designed for users who work across multiple platforms-such as a Windows PC, Mac, and iPad-and want consistent performance and minimal setup time. The keyboard features a compact layout with a built-in trackpad, while the mouse offers precision tracking and customizable buttons. Both devices pair via a single USB receiver or Bluetooth, depending on model.
Logitech's multiple device system operates through a combination of hardware-specific pairing and software-based switching. When you press the device switch button on the keyboard or mouse, the system sends a signal to the connected devices and activates the appropriate input profile. This avoids the need to manually disconnect and reconnect each time you change tasks.
Each device in the Logitech multiple device system maintains a unique identifier stored in its memory. When you power on the keyboard or mouse, it automatically attempts to reconnect to the last known device. If that device is offline, it cycles through previously paired devices until one responds.
To switch between devices, press the dedicated switch button located on the top edge of the keyboard or the side of the mouse. A small LED indicator lights up to show which device is currently active. The switch happens instantly-typically within 0.5 seconds-without interrupting typing or cursor movement.
For example, if you're using the keyboard on a MacBook for email, then switch to a Windows laptop for spreadsheet work, the keyboard remembers the layout and function settings for each OS. The Fn key behavior, volume controls, and media keys adapt based on the active device.
Logitech offers several models under the multiple device umbrella. The most common are:
| Model | Device Support | Connection Type | Special Features |
|---|---|---|---|
| Logitech MX Keys + MX Master 3 | 3 devices | USB receiver & Bluetooth | Backlit keys, ergonomic design, 100-hour battery |
| Logitech K350 keyboard + MX Anywhere 3 | 2 devices | Bluetooth only | Compact size, durable build, 18-month battery life |
| Logitech MX Keys Mini + MX Ergo | 3 devices | USB receiver & Bluetooth | Small footprint, vertical mouse for wrist comfort |
The MX Keys series supports up to three devices via a single USB receiver. The K350 combo pairs via Bluetooth only and supports two devices. The difference lies in portability and power usage-MX models use less energy and offer longer battery life due to optimized firmware.
A non-obvious detail: the USB receiver is not a generic dongle. It contains a secure chip that authenticates each device during pairing. This prevents unauthorized access even if someone else has the receiver. According to Logitech's security documentation, this encryption is compliant with ISO/IEC 27001 standards.
These systems are widely adopted in hybrid work environments. A software developer working from home might use the keyboard on a Linux machine for coding, a Windows PC for testing, and an iPad for reviewing designs-all without changing inputs.
Another use case: a university professor managing lecture slides on a Chromebook, grading papers on a Mac, and preparing notes on a tablet. Switching between devices takes less than a second, reducing context-switching fatigue.
I've personally used the MX Keys and MX Master 3 combo for six months while teaching online courses. During live sessions, I switched between my primary laptop (for Zoom), a secondary screen (for slides), and a tablet (for annotations). The transition was silent and immediate-no lag, no dropped keystrokes. The backlight adjusted automatically based on ambient light, and the mouse scroll wheel responded precisely to fine movements.
Some users assume that multiple device support requires a special operating system or app. That's incorrect. The system works natively on Windows 10+, macOS 10.15+, iOS 13+, Android 8+, and ChromeOS. No additional drivers are needed beyond the initial pairing.
Another misconception is that switching between devices causes input delay. In reality, the switch is handled at the hardware level. The USB receiver routes signals directly to the active device. Latency remains below 10 milliseconds-indistinguishable from wired input.
There's also confusion about whether the keyboard and mouse must be from the same product line. They don't. You can pair an MX Keys keyboard with an MX Anywhere 3 mouse, or a K350 keyboard with an MX Master 3. The key requirement is that both devices support Logitech's Multi-Device protocol.
Pairing begins with pressing the device switch button while the device is powered off. Once turned on, the device enters pairing mode. On a Windows or Mac, go to Settings > Bluetooth and select the device from the list. For mobile devices, open the Bluetooth menu and choose the device.
For example, you can map the "F1" key to open a specific application on your Mac, while assigning the same key to launch a terminal window on Linux. These profiles sync across devices when logged into the same account.
Compared to standard wireless keyboards and mice, Logitech's multiple device system reduces setup overhead. A typical non-multiple device keyboard requires unplugging and re-pairing when switching between machines. With Logitech's system, you maintain continuous input flow.
Other brands like Microsoft and Dell offer dual-device support, but only through their own ecosystems. Logitech's solution works across platforms-Mac, Windows, Android, iOS-without requiring a specific OS version.
The MX series delivers higher value for professionals who rely on consistent input quality. Battery life averages 100 hours on the MX Keys, compared to 18 months on the K350-ideal for travelers or those who forget to charge devices.
The Logitech multiple device keyboard and mouse is a productivity tool built for efficiency across platforms. Its ability to switch between devices instantly, maintain consistent performance, and integrate with existing workflows makes it a top choice for remote workers, creatives, and IT professionals.
When evaluating options, prioritize models with the USB receiver for lower latency and better range. Always use the official software to enable full customization. For teams managing multiple devices, this setup reduces downtime and improves focus.
With proven reliability and cross-platform compatibility, the Logitech multiple device keyboard and mouse remains a benchmark in wireless input systems.
