Is there a danger if you mix up ground wire and common wire when wiring a light switch?

Power out of a switch is not negative. It is still the "hot" conductor. The ground wire in a switch junction box in home wiring is the bare wire. It is nearly impossible to mix these two wires up. Most likely if the "hot" supply comes into the switch box the neutral wire will be with it. Just wire nut the two white wires together, incoming and outgoing. The two black wires will be connected to the switch to operate the light fixture.

Can you use an American light switch but in the UK using the British system for wiring?
No, the common American light switch is only rated for a maximum of 125 volts.
What color is common wire?
Normally the white wire is neutral, and the black is hot. But if the power comes into the ceiling box and the light is controlled by a switch leg the white my very well be hot. If there is only one wire in the switch box that is a switch leg.
When wiring a wall switch which color wire goes on the common terminal screws?
A typical switch doesn't have a Common screw in the strictest sense, it just has two screws which are each side of the switch. You probably have a a 3-way switch. If you are hooking up a 3-way switch as a normal switch, then connect the Black (Hot) wire to the common and the load to the side of the switch that makes UP the on direction and DOWN is off and doesn't get connected. You can determine for sure if you have a 3-way switch because the word ON and OFF don't appear on the toggle.
Light switch has 4 wire colors red and white and green and black which is the hot wire?
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
In a 3-pin switch what is the significance of the earth pin and from where does it get supply?
The ground, or earth, wire is a safety line. It is there in case something goes wrong. It does not have a supply, but instead connects to a grounding rod and your plubming. The idea is to create an alternate path for electricity in the event of a short. If something breaks in the switch and the metal casing goes live, the electricity now has two new paths to follow. One is the ground, the other is you. The ground is there to give the electiricy a low resistance path to ground so it doesn't pass to ground through you. Assuming you're talking about home light switch wiring? I'd be glad to send some diagrams of different types of switch wiring if that's what you're asking about.

Why would front windshield wipers not turn off?
An electric motor needs 2 primary things for it to run. First, it needs power, second, it needs a ground to complete the electrical circuit. Normally this is controlled by the switch... In this case the wiring diagram needs to be compared to the physical condition of the wiring. If the on/off switch opens/closes the ground, then there is an alternate ground in the circuit probably due to a broken wire. If the on/off switch opens/closes the power, then there usually would be a short in the on/off switch, and the power is spanning the switch. .. Goog luck..

What do you do if your light switch isn't grounded?
Older house wiring didn't always use a ground wire. It's acceptable to continue to use the older wiring, but if you update your wiring, anything that you improve must meet current wiring standards. You can replace a faulty light switch without updating the rest of the wiring, but if you bring the house up to modern standards it will improve the safety standards. If you can afford to upgrade your house wiring, the payoff will be worth it.
How did they use to wire two on off switches to one fixture?
You need two 3-way switches. To see a diagram use your favorite search engine and search for 3-way switch wiring. Each switch has a common connection point and two other terminals. Basically connect the "other" terminal on 1 switch to either "other" terminal on the second switch and then do it again for the remaining "other" terminal. Then connect the common on one switch to the fixture and the common on the remaining switch to supply voltage. Tie neutral and ground for fixture and supply to the white and bare wires respectively.
