It uses a standard 5.5mm x 2.1mm DC barrel plugs to fit in between your 12V DC power source and an LED Light Strip with no cutting or wiring needed! DC 12V Inline Rocker Switch for devices with 5.5 mm x 2.1 mm DC connectors.
This is a great replacement for a failed remote control unit that came with lights I bought a few years ago. The switch is less complicated and less likely to have something go wrong.
One Happy Customer!
