Why won't a three way lamp switch work on all three settings when used in a outlet controlled by a wall switch?

If the wall switch is on, the three way lamp switch should work. If it doesn't, it may be broken or there may be something else wrong with the circuit.


Why won't a three way lamp switch work with a wall controlled outlet?

Not wanting to state the obvious but the wall switch has to be turned on to supply voltage to the outlet. The lamp will need a three way light bulb in the lamp. A three way bulb uses two filaments of different lengths. One element is used for low brightness, the other filament for medium brightness and the high brightness setting uses both filaments in the bulb. If a single filament ordinary light bulb is used in place of a three way light bulb there will be a position on the three way lamp switch where the bulb will not light. Find the position on the lamp where the bulb will light and leave it there. Use the wall switch to turn the lamp off and on through the controlled receptacle.


How do you connect a grounded lamp to a ungrounded outlet?

Change the outlet to a grounded one. Get an adapter that goes from 3 prong to 2. Break the ground prong off. Any one of these will work.


Can you plug a 250 volt lamp into US outlet?

Yes. If the plug (cap) end of the 250 volt lamp is compatible to the receptacle the lamp would work. The light output of the lamp would not be very bright. Because the working voltage is halved so would the light output.


How do you power an outlet from a one wire light switch on same wall?

The one wire carries the electricity or voltage. The lamp is grounded completing the circuit. You don't. The light switch is only half the circuit, a lamp has nothing to ground to so it can not work. If the wire to the switch is 3 wire, the bare wire would complete the circuit and power the plug, but it would not be up to code and could present a fire hazzard.

The same as any other light. The plug is inserted into the wall outlet which inturn supplies power to the switch. If the switch is in On, current will flow to the bulb. this causes the light to come on. When the switch is turned off, the current stops there.

How do you rewire UK lamps to work in Canada?

you need a transformer (instead of rewiring) from 220v to 110v The above answer will work but it is not correct. All lighting fixtures installed in Canada have to be CSA certified.

Change out the lamp cord and plug end along with the lamp (bulb) holder and you will have a certified fixture.
