Most modern switches have screw terminals on each side and may also have holes in the back to accept the end of the wire. You can easily loosen the screws on the side of the device with a standard screwdriver turning counterclockwise , but you may find getting the wires out of the back of the device tricky. To remove these wires, insert the blade of a small screwdriver into the slot under the hole into which the wire is inserted and push in as you pull the wire loose. Pushing the blade of the screwdriver into the slot releases the grip on the inserted wire.
Here are descriptions of the wires and where they go: The white neutral wire connects to the silver screw, or you place it in the back wire hole on the same side of the device as the silver screw. The black hot wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw.
This wire is sometimes red. The green or bare copper ground wire, if the device has one, attaches to the green screw terminal on the switch or to the electrical box. To replace this kind of switch, follow these steps: Turn off the power to the switch at the main circuit breaker or fuse panel. Unscrew and remove the switch plate; then use a voltage tester to make sure that the circuit is dead.

I want to replace an existing pilot light switch with a single-way lighted switch. The existing setup has four terminals red wire, black wire, white wire, and ground wire. The red wire goes to the left, the black wire Yesterday we turned ON We have Honeywell D thermostat. We recently turned ON our Fan switch in the thermostat.
At the other switch location, you will hook the white wire from the #14/3 to the white wire going up to the light. Step Eight: The “travelers” (black and red) from the #14/3 will connect to the same screws as on the other 3-way switch, and the black wire going to the light will tie on to the “common” screw.
Electrical tape Video of the Day The first thing you will have to realize is that you can only replace ONE of the existing three-way switches with a three-way dimmer switch. If you try and replace them both, the circuit will not work. Therefore, choose to replace the three-way switch that you will probably use the most to control the lighting. Find the circuit breaker that is delivering the power to the lighting circuit and toggle it OFF.
Flip each three-way switch to make sure the circuit is off. Remove the cover plate from the switch and remove the two screws securing the switch to the wall box. Gently pull the switch out of the box by pulling on the top and bottom tabs. Do not touch the sides of the switch. With the switch out of the box, use your voltage tester to ensure that the circuit is truly off. Take a moment and look at how the switch is wired. One side of the switch should have a single red wire attached to it and the other side should have either two black wires and the ground or a black wire, a white wire with a strip of black electrical tape on it and the ground wire.
Remove the red wire and bend it out of the way. Remove the two black wires or the black and taped white wires and bend them out of the way.

My cat used to drink from the garden pond and never seemed to suffer any ill effects, and you often see dogs drinking from muddy puddles. So why do humans have to be so careful and only drink clean water? Will it form sediment that gets buried beneath the seabed and eventually turns into plastic “oil” or “coal”? I had previously suspected that some tadpoles are late undergoing metamorphosis, but this one really missed the boat. Is this a recognised phenomenon, and what is the explanation?
Is there an accepted ratio or does it vary, and if so by how much? Does this mean there would have been three sets of chicken twins? But are plants included in this universal common ancestor? If so, are we linked to plants in very early stages of evolution? What is it made of and what is the typical wall thickness of this amazing auger? Also, what is the minimum capillary diameter through which blood could be sucked?

Three-way and four-way switches[ edit ] A double pole, double throw switch wired to act as a four-way intermediate or crossover switch This article follows American usage. The controlled load is often a lamp, but multiway switching is used to control other electrical loads, such as an electrical outlet, fans, pumps, heaters or other appliances. The electrical load may be permanently hard-wired, or plugged into a switched receptacle.
Three-way and four-way switches make it possible to control a light from multiple locations, such as the top and bottom of a stairway, either end of a long hallway, or multiple doorways into a large room. These switches appear externally similar to single pole, single throw SPST switches, but have extra connections which allow a circuit to be controlled from multiple locations. Toggling the switch disconnects one “traveler” terminal and connects the other.

Changing Outlets Outlets receptacles have to withstand the wear and tear of yanking cords out of the sockets.
If an outlet is loose, or anything that’s plugged into it flickers on and off, it’s time to be replaced. On its back side, an outlet is rated for voltage and amperage volts and 15 amps is most common. Make sure to get a replacement with the same ratings. Turn off the circuit breaker that controls the outlet. Test that the power is off by sticking both circuit tester probes in the outlet slots of each socket.
No light means the power is off. Take off the cover plate. Just to be safe, test the circuit again. This time, touch the probe to the screw terminals on both sides where the wires are attached.
