- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CAB-25579:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)

## Description

Need a USB-C cable that allows you to transfer data *and* switch the power? This is it!

There are plenty of USB power switch cables out there. But all they do is switch power. Switch cables that also transfer data are very difficult to find, especially USB-C ones. Sparkfun designed this cable to fill that gap. Not only does it switch VBUS power, the USB 2.0 D+ / D- pins, the two Configuration Channel (CC1 & CC2) pins and the shield are connected too. The TPE sleeve is soft and durable. This makes it a *powerful* cable!

If, like us, you regularly have a Thing Plus board, or a GNSS board, or an RTK product connected to your computer, you'll know how useful it can be to turn it off and back on again without needing to unplug it. This cable allows you to do that. Or you are measuring the battery life of your USB-enabled project; you need USB data but don't want USB power to recharge the battery. This cable allows you to do that too. Testing a board which has Power-over-Ethernet (PoE)? You need USB data but you want PoE to provide the power, not USB. This cable is the perfect choice. Pair it with a standard [USB A to C cable](https://core-electronics.com.au/usb-3-1-cable-a-to-c-3-foot.html) and away you go!
