This USB 2.0 pigtail cable has an inline ON/OFF switch and a male DC barrel plug, making it the simplest way to add a hardware power switch to LED strips, lamps, fans, and other USB-powered gadgets. It is built for cutting power to a 5 V or 12 V load without unplugging the cable, and ships in 100, 150, or 200 cm lengths with 22 AWG copper conductor and PVC insulation.
Product Description
This is a 22 AWG USB 2.0 to DC pigtail cable with an integrated rocker switch midway down the run. USB-A goes into the source side and a 5.5 x 2.1 mm DC barrel plug terminates the load side. The switch breaks the positive line so the device sees a true power-off state when the switch is open — useful for LED strips and lamps that have no built-in switch, USB fans, and any always-plugged USB gadget where soft-off behavior is not enough.
The conductor is copper, the insulation is PVC, and the cable is rated for the typical 3 A continuous load that a USB-PD or boosted USB source might deliver. Three lengths are available so you can match the run to the install: 100 cm for desktop, 150 cm for shelving, 200 cm for floor-to-table runs.
Key Benefits
- Inline ON/OFF rocker switch — cut power without unplugging
- Premium 22 AWG copper conductor for stable performance under continuous load
- USB 2.0 source side compatible with chargers, power banks, hubs, and laptop ports
- 5.5 x 2.1 mm DC barrel plug fits the most common LED strip and small-appliance jacks
- Three length options (100 / 150 / 200 cm) cover desktop to floor installations
Key Features
The defining feature is the inline switch, which lets you toggle a connected device off and on without disconnecting the USB source. This is meaningfully more convenient than yanking the plug for LED strips that you turn off nightly, USB fans, lamps, or any small device whose own controls are awkward to reach. The 22 AWG conductor sits well within its ampacity at the 3 A continuous rating, the PVC jacket stays flexible at desk temperature, and the 5.5 x 2.1 mm DC plug matches the largest installed base of low-power consumer DC inputs.

What's Included
- 1 x USB pigtail cable assembly with inline ON/OFF switch (per selected length)
Compatibility & Applications
This cable is compatible with any USB 2.0 Type-A power source and any 5 V or 12 V device that uses a 5.5 x 2.1 mm center-positive DC barrel jack and draws no more than 3 A continuous. Typical applications include:
- LED strip lights and lamps without built-in switches
- USB-powered light bulbs and accent lighting
- Small USB fans and hobby devices
- USB-PD bench power for prototyping
- Always-plugged gadgets that need a hardware off control
Not compatible with: 5.5 x 2.5 mm jacks (different inner diameter), center-negative devices (polarity reversal will damage the load), and devices that require more than 3 A continuous current.

Frequently Asked Questions
Does the switch carry the full 3 A current?
Yes. The integrated rocker switch is rated to handle the cable's full 3 A continuous current at the operating voltage, breaking the positive conductor when in the OFF position. There is no separate fuse, so the source-side current limit applies normally.
What's the practical use case for an inline DC switch?
The most common use is LED strip lights and lamps that have no built-in physical switch — instead of unplugging the USB end every night, you flip the rocker. It is also useful for USB-powered fans, prototyping benches where you want to cut a load without disconnecting the supply, and any always-plugged USB gadget where soft-off mode still draws standby current.
Will it work with 12 V or only 5 V from USB?
The cable itself supports both. Standard USB 2.0 outputs 5 V; for 12 V you need a USB-PD source with a trigger cable or a USB-C PD adapter that negotiates 12 V. The cable conducts whatever the source delivers at the chosen polarity.
How fast does shipping take?
Orders are dispatched from regional fulfillment partners in North America, Europe, and Asia. Typical delivery is 5 to 15 business days depending on destination country, with tracked shipping included. Specific timelines per destination are listed in the Shipping Policy.
How does this switched USB pigtail compare to others in its category?
Within the switched-USB pigtail category, the meaningful comparison points are switch current rating, conductor gauge, and the polarity of the switched line. This product uses a 3 A rocker switch, 22 AWG copper, and a positive-line break with center-positive 5.5 x 2.1 mm output — the configuration that fits the largest installed base of LED strips and small USB-powered devices and drives the lowest return rate within our small-electronics category.
