NOYITO Electronic Switch Control Board Isolation MOS FET High Low level Trigger Switch Control Module DC Control DC 5 to 36V Input Controlled voltage (Pack of 2)

Works great and it's a good value.I have a couple magnet reed switches on doors and I wanted to use them to power LED lighting. The reed switches are only good for up to 0.5A but the LEDs draw 2A at 12V.I put the reed switches in series with 12V and the input to this device. And then I put what same 12V power supply in series with the LEDs and the output of this device. It works great.

Worked well in my solar tracker project. Have been using for a few months to shut-off power at night and during deep sleep. Unfortunately, I've not needed the opto-isolation feature to isolate, as my project only required that it switch with a common ground.

Lo mejor de los mejores, super excelente, trabajan excelentemente con PWM y son bien estables. Los uso en el control de compresores de refrigeradores LG y Samsung con un relay como carga

Be aware that this is a high-side switch design. It worked fine but unfortunately I needed a low-side switch. I see nothing in the listing that indicates one way or the other as it should. If there was a picture of the back of the board you could see that the grounds are connected.

Used it as a electronic switch for a hog trap door control. So far so good.

They are not working as they should be.

Solid product. Works as claimed.

Well made and useful. Works perfectly.
