I was just wondering how it can work beside only the hot wire... Is it using the dirt ground? I didn't try wiring it without the ground because I didn't grain like wasting time.
It is internally wired. A wire goes from the hot side, through the switch, through the bulb, and support to ground (or neutral). When the switch is "Off", a differential voltage is created, causing the bulb to light. When the switch is turned "On", one and the same voltage is on both sides of the bulb and therefore, will not light. a switch should own at least 2 cables going into it. 3 if it's a 2 style switch. If there's only 1 live cable and it's using the earth next that is seriously dangerous. Check and see if the floor is connected to the switch mechanism it should only be connected to the backbox.
It can't work with freshly the hot wire. It completes the path by putting current through the oil lamp. However, from your perspective, it appears to involve only the black wire. If you remove the hurricane lantern from the socket, you'll see that the connection to the neutral leg is broken and the switch won't brilliance.
I know it seems weird, but compared to the neon bulb that lights up the switch, the resistance of the "off" oil lamp appears quite small in comparison. So even though the oil lamp is "off", there are a few microamps going through it, enough to wishy-washy the little neon lamp.
When you flip the switch "on", the switch closes, and basically shorts out the neon bulb, which is why it go dark when the switch is on.
There are some new automotive fuses that work on like principle and they will light a very small LED oil lamp when the car's fuse is blown.
Answers: Yep
It NEEDS to be grounded. Don't verbs about how it's illuminated. Magic or VooDoo!
