Customer Reviews (4.8 / 5 · 5 reviews)

Owen Y. ★★★★★

The screw terminals make wiring up my 220V garage light a breeze, and the indicator LED lets me know exactly when the relay is active. Worked perfectly with my Arduino on the first try.

Stella ★★★★★

Switched my desk lamp to this relay and the screw terminals made wiring a breeze, even my shaky soldering wasn't needed. The 220V switching works flawlessly with my Arduino's 5V signal so far.

Edward O. ★★★★★

Controlling a 220V lamp from my phone via an ESP32 was surprisingly easy with this relay, and the screw terminals made wiring a no-brainer. The normally open contact switched cleanly every time, no buzzing or flicker.
