Inline DC switch for low-voltage projects

This two-pack adds a manual on-off switch between a power source and a device using 5.5mm x 2.1mm barrel connectors. Each cable measures 12.5 inches or 32cm overall and is rated for 12 volts with UL listing. It suits LED strip lighting and similar low-voltage applications where a convenient power control point is needed.

Simple plug-in installation with polarity care

The male and female barrels connect inline without tools, but the centre-positive 2.1mm pin must match the equipment polarity to avoid damage. The fixed 12.5-inch length may be too short for distant mounting, and the switch handles only the rated 12-volt load. Buyers needing longer reach or higher current capacity should look elsewhere.

Questions about this item

How can I confirm the switch is controlling power to my 12 volt LED strip after installing this 5.5mm x 2.1mm inline cord?

Plug the male barrel into your power supply, connect the female barrel to the LED strip, then toggle the inline switch; the strip should turn on and off instantly with each press.

What comes in the 2-pack and do I need any extra adapters for a standard 5.5mm x 2.1mm barrel jack?

The package contains two 12.5 inch extension cords, each with a male and female 5.5mm x 2.1mm barrel connector; no additional adapters are required for matching jacks.
