5.5×2.1 mm DC power extension with inline switch

This pair of 30 cm cords extends a 12 V DC supply using a standard 5.5 mm by 2.1 mm male-to-female connector. Each cable is built from 18 AWG wire rated for 10 A at 12 V. They suit installers and hobbyists who need a quick way to add reach and on-off control to CCTV cameras, LED strips or similar low-voltage devices.

Inline on-off switch replaces repeated plugging

The integrated switch sits along the cable so power can be cut without unplugging the barrel jack. This reduces wear on device ports and speeds up testing or temporary shutdowns during installation. No cutting, soldering or extra tools are required — just connect the male end to the supply and the female end to the load.

Plug-and-play fit for 5.5×2.1 mm jacks only

Installation is straightforward: verify the jack measures 5.5 mm outer and 2.1 mm inner diameter, then push both connectors until seated. The 300 mm length limits routing flexibility in larger enclosures, and the 10 A rating means the cords must not be used on loads that exceed this current at 12 V.

Questions about this item

Will the inline switch on this 5.5×2.1 mm cable wear out from daily on/off cycles?

The switch is rated for the cable’s 10 A at 12 V load; normal daily use stays well within that rating, so no scheduled replacement is needed.

What stops me from running this 18 AWG lead at its full 10 A continuously?

The 18 AWG conductors and the inline switch are both specified for 10 A at 12 V, so the cable’s own rating is the first limit reached under sustained load.

Does the switch or the 30 cm wire get noticeably warm when powering a 12 V LED strip all day?

At or below the 10 A, 12 V rating the 18 AWG wire and switch run cool; only loads approaching the maximum rating produce detectable warmth.
