RC-T2555 DC Inline Rocker Switch Cable provides convenient manual on/off power control for compatible low-voltage DC electronics equipped with standard 2.5mm x 5.5mm barrel jack connections. Featuring 20 AWG copper conductors, a 12-inch overall cable length, and pre-molded male-to-female DC barrel connectors, this pass-through toggle switch eliminates the need to constantly plug and unplug power adapters.

Important Safety Notice: Maximum continuous rating is 3A. This is a passive pass-through switch cable and does not step up, step down, regulate, or convert voltage. Always verify your power source voltage, load current requirements, connector dimensions, and polarity prior to connection.

Key Features & Applications

Convenient Power Control: Adds an easily accessible manual power switch to 12V/24V LED light strips, bench power setups, desk lamps, and DC electronic devices using 2.5mm jacks.
Reliable 20 AWG Wiring: Built with flexible 20 AWG copper wire ideal for low-to-medium power DC applications drawing up to 3A continuous load.
Plug-and-Play Installation: Splicing-free design with pre-molded strain relief on both 2.5mm x 5.5mm connectors for reliable longevity in DIY electronics setups.
Equipment Protection: Protects equipment power jacks and power supply cords from premature wear and tear caused by frequent mechanical disconnects.

Compatibility Notes

Designed exclusively for compatible low-voltage DC circuits. Do not connect directly to AC household mains outlets.
Ensure your device utilizes a 2.5mm inside diameter (ID) and 5.5mm outside diameter (OD) barrel connector. Will NOT fit 2.1mm x 5.5mm power jacks without an adapter.
Keep total power load at or below the 3 Amp maximum current rating (e.g., 36W at 12V or 72W at 24V).

Frequently Asked Questions

What is the purpose of the RC-T2555 inline switch cable?
It inserts a physical on/off rocker switch directly into a 2.5 x 5.5mm DC power line, allowing you to turn connected DC devices on and off without unplugging the power adapter.

Will this cable step down or regulate 12V to 5V power?
No. The RC-T2555 is a straight pass-through cable. Whatever voltage enters the female connector flows straight through to the male plug when switched ON.

Is the RC-T2555 interchangeable with the RC-T2155?
No. RC-T2555 uses a 2.5mm center pin, whereas RC-T2155 uses a 2.1mm center pin. Always verify pin diameter prior to ordering.

Works Great

Works as advertised. Good price, good delivery, everything works

It didn't fit

I'm not so sure this is actually 2.1mm, it fits 2.5mm....

Thank you for your order and taking the time to leave a review. Please note the item you order and that was shipped is a 2.5x5.5mm male and female. It is not inteneded to be used for a 2.1x5.5mm. That would be a different part number. We are happy to assist if there are any additional questions you may have.
