## Description

A 2.1 mm DC barrel jack with a built-in slide switch, giving you simple on/off control for devices that lack a dedicated power switch. It shares the same PCB footprint as a standard non-switched barrel jack, so it drops straight into existing designs without layout changes. Plug in your power supply (up to 16 VDC, 3 A), then use the labelled slide switch to toggle power on and off — no more unplugging cables every time you want to cut power. Key Features Integrated Slide Switch – Labelled on/off toggle on top of the jack Standard 2.1 mm Barrel Jack – Compatible with common DC wall adapters Same PCB Footprint – Drop-in replacement for non-switched barrel jacks Rated up to 16 VDC, 3 A – Suitable for most maker and prototyping projects Tip: Prefer a rocker switch?
