How to use a relay as a switch (#23 AC and Switching Circuits)
Let's switch a lamp on and off using a relay in a circuit. We'll use both non-latching and latching relays. Relays are useful for using small signals to switch on and off larger signals, like mains voltages. Here we use a 5 VDC signal to switch a lamp on and off, with the lamp operating at 230 VAC. This video series introduces basic AC circuit ...
