How do you wire a tri-light bulb table lamp with 3 wire rotary switch?

If the tri-light needs a new lamp holder try any reputable lighting house store. These types of retailers have all of the parts that you need to repair any lamp configurations. The new switch will have a rotary switch built into it just like the lamp had when it was new. There are only two wires to connect to it. Don't disconnect the old one until you have the new one and just put the wires on the same terminals as the they are wires on the old switch.


How do you connect 2 black and 2 red wires to a new switch?

switches work by interupting the hot side of a wire loop, so what you do is you wire your non hot (usually black) wires directly to the device you are trying to control, next, to one side of the switch you connect your two reds, then to the other side of the switch connet the hot lead from your device.

Difference between one way switch and two way switch?

A 'one way' switch is typically considered a 'single pole' switch with essentially one contact for the connection of an electrical circuit. A 'two way' switch probably refers to what is considered a 'three way' switch. where a single, common terminal can be connect to one of two possible contact points. (One incoming wire, and two potential 'outgoing' connections. A single pole switch is typical used when a device (light switch, fan, receptacle) only needs to be controlled from one location. A 'three way switch' is used when a device needs to be controlled from more than one (I.E. the top and bottom of a stairway, at both ends of a hallway) A three way switch allows for a device to be controlled independently from two locations, regardless of the position of the other switch.

How do you connect a new convenience outlet to a 3 way switch in different locations?

This can be tricky. You can only place a receptacle from the location of the box where the three way circuit is fed from. The wires from the three way to three way boxes only carry the "hot' traveller wires. There is no neutral carried from box to box even though there might be a white wire in the three wire group. So you have to locate where in the three way system the hot and neutral wires are located. From this location you can extend new black and white wires to your new receptacle outlet.


How do you switch the wiring from a regular light switch with three wires to a spring wound interval timer with only two wire spots?

If there are three current carrying conductors terminated on the switch you want to replace, then you can not use the new switch at this location. What it sounds like is the existing switch is part of a three way light switching circuit. Check online for images of "wiring of three way switching systems" and you will see what I mean.A regular light switch will only have two termination points on the switch. This type of switch could be a direct substitute for the interval timer switch, as both have only two terminal points.The only way that you could use the new switch in this circuit is to cut in a new junction box for the new switch adjacent to one of the existing light switch boxes. One end of the circuit would use the new switch for opening the incoming "hot" conductor or at the other end of the circuit, the new switch would open the conductor that goes to the light (load). If this method is used the existing switches will not be used for controlling the light and must be in a position so that the light will be always in the on position.If the three way switching is not needed then the existing switches can be removed and the wiring in the boxes can be rewired to accommodate the new switch and the other box would be blanked off.


How do you remove ignition switch 1966 Chevy truck?

As you look at the switch there should be a ring with three notches or groves, this is the nut that holds the switch in. If you are careful, you can use a regular screwdriver in one of the groves and tap it with a hammer to break the nut loose. You should then be able to remove the nut by hand and push the switch through the dash. Reach under the dash and pull the switch down so you can see the wires on the back. I am not 100% sure if it is a single plug or if there are several wires (although I believe it will be several separate wires). If you are putting in a new switch, make sure you have the new, and correct switch for the next step, remove the wires one at a time and reinstall them on the new switch. Once you are done with this, just put the switch back in and you're done. Hayden
