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


How do you wire an up down switch?

You only have to break the black wire because it is the hot wire.


How do you wire a 20A switch which comes with a neutral wire when only 2 wires are available for the circuit?

You never switch a neutral wire, only hots. hooking both hot and neutral to the same switch will result in a short when the swith is turned on.


How do you add another porch light to an existing switch?

Piggyback off the box for the existing light. Run a wire from the existing junction box to a new junction box (which is placed wherever you want the new fixture). Then, in the existing box, connect the wire coming from the switch, the wire for the existing fixture, and the wire for the new fixture together using wire nuts. Wire up the new fixture, and presto, you have two fixtures on a switch where there was only one before.


Can you replace a 3-way light switch with a standard switch and cap off the wires or can you use the 3-way switch and make it into a standard switch?

It can be done but it requires knowledge about how a 3way is wired to convert it to a regular switch. It would involve testing live wires to determine where power starts at. You can't just replace one switch.

How do you Connect on and off switch between continuous wire?

First you turn off the power. Then you cut the wire. Strip each end of the cut wire and attach to each side of the switch. This should only be done within a switch enclosure. If there is no extra wire to make a good connection, you can extend the cut ends with wire of the same size as the cut wire and use wire nuts to securely connect the "pigtail" wires. You should only switch the hot side (Black wire in home wiring) and not the white wire which would pose a shock hazard.


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.


Is there a way to tell if the power window switch is bad or if it the motor for the switch?

remove switch from where it is mounted using a wire , bridge the connections.if switch is bad, it will work the motor while bridged


What does a 4 way switch do?

For starters, a four way switch must be connected to either a four way switch or a three way switch on either side. Said differently, here are some common combinations: 3way---------4way-----------3way 3way---------4way-----------4way------------3way 3way---------4way-----------4way------------4way----------------3way etc. If you are using a four way switch anywhere in a circuit both ends must have three way switches. You can use as few as one four way between the three ways, or as many as you would like. First of all, connect your white (neutral) wire straight through every box, from the power source to the light fixture being controlled. That neutral has nothing to do with the switches. On your three way switches you will see two bright screws and one dark. (Excluding the green grounding screw). One three way switch will have its dark screw connected to the power source. Two wires will run from the bright screws to the next box (the 4 way switch box). Those two wires will connect to the two bright screws on one side of the four way. The four way also has dark screws, but two of them. Connect two wires to these two dark screws, and run them to the next switch box. If the next switch box is another 4 way, repeat this again and again until you get to the last switch (a three way). Wire the last three way as follows: the two wires coming from the previous 4 way go to the bright screws. The hot wire feeding the light fixture will be the one to connect to the single dark terminal of the last 3 way switch. That's it! As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.


Where hook up interior lights in 1969 Chevrolet?

I believe that it is a grounding switch. If that is the case it would only have one wire going to the switch. You could run this wire to any fused constant hot. The wire would run from the hot, to the light, to the switch.


Can you connect black wire to red wire?

In some cases in residential wiring you do. From a light fixture junction box to a switch box, the cable is a two wire, black and white. To connect the switch into the circuit at the fixture box, the "hot" conductor is connected to the white wire that goes down to the switch. The switched "hot" comes back on the black wire and this is then connected to the fixtures black wire. The white (neutral) is picked up in the fixtures junction box and connected to the fixtures white wire.
