A 1-metre USB-C extension cable with an inline power switch that maintains full USB 2.0 data connectivity. Unlike typical USB power switch cables that only toggle VBUS, this cable also connects the D+/D- data lines, both Configuration Channel pins (CC1 and CC2), and the shield — giving you complete control without sacrificing data transfer.
Perfect for development workflows where you need to power-cycle a connected board without unplugging it. Whether you're debugging a Thing Plus, testing battery life without USB charging, or using Power-over-Ethernet while keeping a USB data link, this cable makes it simple.
Key Features
- Inline Power Switch – Toggle VBUS power on and off without disconnecting the cable
- Full USB 2.0 Data – D+/D- data lines connected through, unlike power-only switch cables
- CC1 & CC2 Connected – Both USB-C Configuration Channel pins pass through for proper USB-C negotiation
- Shielded – Shield connection maintained for signal integrity
- TPE Sleeve – Soft, durable cable jacket built to last
- 1m Length – Generous cable length for bench setups
Ideal For
- Power-cycling development boards without unplugging
- Battery life testing — keep USB data while disabling USB power
- Power-over-Ethernet (PoE) setups that need USB data without USB power
- Any project requiring independent control of USB power and data

- 1× USB-C Extension Cable with Power Switch (1m)
Jargon buster
Plain-language definitions for the technical terms used above.
- PoE
- Power over Ethernet lets one Ethernet cable carry both network data and electrical power. This is useful when installing a device where running a separate power adaptor would be difficult.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- Thing Plus
- Thing Plus is SparkFun’s development-board form factor with a small rectangular layout and connections suited to wireless and battery-powered projects. It matters because boards and accessories in the same form factor are easier to mount, wire, and swap between projects.
- USB 2.0
- USB 2.0 is a widely used wired standard for carrying both data and power between a device and a computer or other compatible host, with data rates up to 480 Mbps. It indicates the kind of port a device uses and that it should work with most modern and many older computers.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
- VBUS
- VBUS is a label for a bus or supply voltage. Most commonly it is the +5V power line carried over USB, though on power-monitoring hardware it instead marks the bus-voltage input being measured, so check which sense applies before connecting power or a measurement point.
