Posted - Sep 27 2010 : 10:22:41 PM Hi, i need to swith on or off a 120VAC lights with a 12VDC, 60 to 800mA. I think i could do this with a relay but i'm not shure. I guess so i need a diode to protect the relay. Can you guys help me? If it's possible, can you send me a diagram? Thanks |

This uses a 24 volt DC supply and your using 12V. You just replace the 24 volt to 12 V. This would be a reference for you. Hope this helps. For more information, you can search google for transistor switch circuits. |

yes it can be done as you think just be sure you buy the correct rated relay and be sure the relay is an AC relay
What is an AC relay? The load and contacts use AC but the coil uses DC.
