Review on 🔌 Efficiently Monitor and Control Appliances with the Zerodis Appliance Switch Feed Through Indicator by Kenneth Witte

*The description says it's an LED but it's a neon bulb.*The wiring diagram is wrong. However, you can use a meter to figure out how to connect it. Tips: Follow the "Line" and "Neutral" markings on the switch itself, not the schematic. The neutral terminals are always connected and the line terminals go through the switch. You can tell which side of the switch the neon light is connected to. If you want the lamp to be on all the time, apply power to the neon side of the switch and connect the load to the other side. If you want the neon to switch on and off with the load, connect the load to the same side of the switch as the neon and the incoming power to the other side (this is the opposite of what is shown in the diagram ). So far, so good. with the switch as soon as I plugged it in the way I wanted it!
