By means of a relay, a circuit with much more power can be switched with a relatively small current.
Customer reviews about Relay modules
Tim GTimer relay module - 12VI had a little trouble setting the correct mode, but once you get the hang of how the buttons work, it's pretty easy to operate.
FloRelay module 5VWorks perfectly. I use it to trigger a plasma cutter from a Creality Falcon 10w engraver. Requires adding a 5V power supply ( USB in my case) to avoid IO collapse
Anonymous5V Relay module 2 channelsProduct is exactly as described and works well. Perhaps a small manual could have been included about the inputs (low active) and the jumper for separate power supply.
