A 2.1 mm DC barrel jack with a built-in rocker switch, giving you a 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 rocker switch to toggle power on and off — no more unplugging cables every time you want to cut power.

Key Features

• Integrated Rocker 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

Ideal For

• Adding a power switch to boards that don't have one
• Custom enclosures and project boxes
• Prototyping and bench setups where quick power toggling is convenient
