Can you use a compass to detect the currents in wires in the walls near light switches in your home?

Yes, the needle would point perpendicular to the wire, and parallels to the magnetic lines of the wire.
Another answer The above answer would be correct IF you were dealing with a DC circuit AND there was a load on the circuit, but house wiring uses Alternating Current, and the compass needle would attempt to reverse directions at the rate of 60 cycles per second. Effectively, the needle would simply act strange when it's near house wiring, IF there is a current load on the wire.

To add to that, use a proper cable-locator, not a compass.

Where can you purchase light switches online?
Light switches can be purchased from SparkyDirect, they have a huge range of light switches other websites offering light switches are HomeBase, argos and ebay.
What will happen if the two switches connected to light up a single bulb are on?
It is dependant on whether the switches are in wired in a parallel or series configuration. If the switches are wires in parallel then both switches would have to be off to turn the light bulb off. Either switch could turn the light bulb on. If the switches are wired in series then both switches would have to be on to turn the light bulb on. Either switch could turn the light bulb off.
What are light switches made from?
Modern light switches are made from plastic, copper, and (maybe) coiled steel springs.
Your light has a dimmer switch on and the light wont work?
Dimmer switches go bad, more often than regular switches.
Is it required for bathroom light switches to be protected by the GFCI?
the oulets yes the switches would be a no

Is a compass safe?
the compass safe because is light and easy-to-carry.
Where are light switches made?
In a light switch factory......
If you have a light in your kitchen operated by two different switches is it right that you should still get a power reading when the switches are off?
Yes, because the light is using 3-way switches. There is always "power" travelling between the switches.
Your light has a dimmer switch on and the light wont work?
Dimmer switches go bad, more often than regular switches.
Suppose you have a single light that can be turned on and off by 2 separate switches if you flick both switches at exactly the same time what will happen?
The single light will not come on. The traveler legs from the two switches will have to be opened simultaneously if they are not then you will get a flick of light.
Is it required for bathroom light switches to be protected by the GFCI?
the oulets yes the switches would be a no
What are different kinds of switches?
Mercury tilt switch, Knife switch, Footswitch, Reversing switch, Light switches, Electronic switches
Interior light stays on when all doors are shut 96 jeep grand Cherokee?
Two possibilities; the dash switch is set to ON that operates the interior lights, or one or more of the switches that detect a door open has failed.
