I have Two black wires and one red wire conected to a switch. Which is hot and which is neutral?
It sounds like your switch is a three way switch. The wire that is on the different colour screw of the three screws will either be the "hot" wire or the wire to the load. The neutral might or might not be in the box that the switch is in depending on which end of the three way system you are at. See discuss question button below.No wires connected to a switch are neutral. A switch breaks the circuit of the hot wire. Black AND red are hot wires. White is used for neutral and is almost never connected to a switch.
Does the black wire go on the gold screw for a three way light switch?
That depends on where the other end of the wire goes.
How do you connect two way electrical switch?
The two way switches work in pairs. We find most of them in our houses where the light bulb can be operated by two switches each at the far end to the other. Each switch consists of three terminals two of which are connected. When one switch is open and the other is closed then the bulb glows and viceversa
You have three wires on the new switch but only two on the old?
The new switch is a 3 way switch which requires a common and 2 traveler's. The switch can be identified by no on off marks on toggle part on face of switch. Unless that third wire is a ground wire.
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.
Is there a way to wire a 3 way household dimmer switch as a 2 way dimmer switch?
You need a three way switch to control lights from two locations. The name is misleading. Three way switch refers to the connection points on the switch. You can use a three way switch as a single switch as long as you place hot wire on the brass screw and the use any of the other screws for the return hot.
Can you replace an old no ground single switch with a three way switch?
A three way switch can be used as a single switch. Replacing this switch will not allow you to switch a fixture from two locations unless there is a three wire cable going to the second box.

How do you wire a 2 way light switch down stairs to a 1 way switch up stairs?
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
Single light switch you want to put in a double for your fan and light how do you do it?
You have to pull a new wire. There is no way to do it with the existing wire, at least no way you should do it and be in code.
Can a three way switch be changed to a single pole switch with a plate over one of the switch locations?
Yes, If you only hook up two wire it will work as a single pole
Is it possible to run power from a three way switch to install an outlet?
Yes you just have to "steal" power from the switch. Do this by running a pigtail wire from the hot of the switch to the hot wire of the plug. Make sure you do this before the switch or you will end up with your outlet being switched as well.
When installing lights with 2-way and intermediate switching control the intermediate switch must be connected to the?
to wire a lamp to be controlled from three places you need two three way switches and one four way switch. the two traveller wires that would normally run between the two three way switches must be connected to the terminals of the four way switch
