Smaller hooks exist and are marked by numbers, but those steel hooks are mostly used for very fine yarn and thread, and they won’t be covered here. Yarn weights, also, are designated by numbers, and those range from 0 to 6, with 6 being the thickest and 0 being the thinnest. Each yarn weight works the best with a few different hook sizes. If you need help choosing a crochet hook, we have a helpful guide to how to find your best crochet hook size , or you can check the yarn label when buying your yarn. Most labels will list the recommended yarn weight, though you can still switch it up if you tend to crochet tightly or loosely or you’re going after a specific effect.

Fully explained wiring instructions complete with a picture series of an installation and wiring diagrams can be found here in the GFI and Light Switch area here in this website. Just click the Wiring Diagrams…. I have an existing light switch, and I want to add a second switch for a new light that will be operated separately. The power comes into the switch which operates a single light at the end of the circuit.

Is there a simple way to do this or should I get an electrician? Adding a Light Switch and Fixture to an Existing Switch The task of installing additional wiring for a light switch and new light fixture will depend on available access to the proposed location.

Prices will vary but it will probably cost between $40 and $ to have someone come out and replace a light switch for you. New light switches are a couple of dollars (more for dimmers) and take ten to fifteen minutes to change.

Single light circuits Below is perhaps the simplest arrangement, panel to switch to switch to light: Below is a variation with the light between the two switches, i. In this case, the end of the white wire from the light box to the right switch must be re-marked black to indicate that it is a hot wire: Next is a circuit with the light between the two switches, but with the panel feeding the light box.

As you do so make a note of how everything is hooked up. You need to identify which color wire is what. Here is the scheme used by most sensors: It will most likely be the white neutral one since the sensor switches the black hot one. I have seen sensors that switched neutral before though. How you do this will depend on the exact sensor you have. Find the relay Look at the component side of the circuit board.

You need to find the relay the part that acts like the switch. Here is the relay in my sensor:

If it’s the last thing I do! The world’s most famous crook! He is the captain of a crew of pirates aboard the Jolly Roger and the archenemy of Peter Pan. Captain Hook has long since abandoned sailing the high seas in favor of having revenge on Peter Pan for cutting off his left hand and feeding it to Tick-Tock, considering it, by Mr. Smee , a “childish prank”. While a worthy opponent for Peter Pan, Hook is destined to fail, sometimes because of Peter Pan’s ability to fly, but more often through the bumbling actions of his first mate, Mr.

Smee, who while unquestioningly faithful to the Captain, is incompetent and dim-witted. Hook ends up fleeing for his life from the Crocodile, of whom he is understandably terrified. Hook’s frustrations are understandable; he lost a hand to his opponent, is constantly pursued by the crocodile and cannot fly.

Mellanox Poised For HDR InfiniBand Quantum Leap

How to Hook Up a DVD Player. DVDs are ubiquitous in the entertainment world today, and DVD players can be purchased for less than the price of a nice dinner. Hooking up a DVD player to your TV will give you access to countless hours of.

But the one thing they cannot do is get too far out ahead of the PCI-Express bus through which network interface cards hook into processors. This, more than any other factor, is why Mellanox Technologies, which has been champing at the bit to double up the speed of its InfiniBand switching, is not expected to ramp up the Quantum InfiniBand switch chips until the middle of next year.

As has been the case with prior generations of devices across every switch maker, customers do not always have to use the top speed per port that is available when they buy a switch. Rather, they can use cable splitters to cut the bandwidth per port by a factor of two or sometimes four and jack up the effective port density in the switch and therefore the rack.

There is generally a two year cadence between speed bumps, so look for an announcement in November on that and deployments maybe 12 months to 18 months later, depending on where the CPU and PCI-Express roadmaps are at in their cycles. Here is the neat bit. By doing so, either Mellanox or its switch customers could jack up the port density on the device by 2X and cut the bill of materials by a lot two because it would take two 40 port switches with two ASICs, two power supplies, and two enclosures to do the same task.

Each leaf in the modular switch has a single Quantum ASIC, with 20 ports facing out to the servers and storage and 20 facing inwards to the backplane of the switch. That backplane is a fully connected fat tree topology that is implemented using 20 of the Quantum ASICs. It is like a two-layer leaf-spine network with no oversubscription of ports in a single box, in essence, and multiple of these director switches can be linked to each other to create a three-layer network.

There are two common ways to wire a switched light. The first method shown in both of Eric’s diagrams is to bring both the “Hot” black wire and common or neutral white wire into the switch’s box. The white wire is passed on to the light fixture and the black one is connected to the “in” side of the switch.

A black wire is then taken from the “out” side of the switch on up to the other terminal on the light fixture. If your circuit were wired this way, it would be easy to add an outlet, using Eric’s diagrams. A wire, connected to the other side of the switch and is sent back up to the light’s box where it is connected to the other side of the light fixture.

Edit Article How to Wire a Double Switch. In this Article: Removing Old Switches Installing a Double Switch Troubleshooting Community Q&A A double-switch allows you to operate two lights or appliances from the same location. Double switches, sometimes called “double pole,” allow you to separately control the power being sent to multiple places from the same switch.

This would be a two wire cable black, white, ground take the black wire and connect it to one screw on the switch and connect the ground wire to a screw inside the electrical switch box mounted to the wall. Now run a two wire cable from the first light location to the switch box. Connect the black wire from it to the other screw on the switch and the ground wire to the box as before. Now take both white wires and connect them with a marrette wire connecter and fold them into the back of the electrical box out of the way.

This will complete your switch connection. Now for all light locations run a two wire cable from one location to the next,this should give you two, two wire cables at every light location except the very last one, it should have only one two wire cable. Make sure to allow extra wire at each switch or fixture to work with easily so that it is not to short.

Double switches, sometimes called “double pole,” allow you to separately control the power being sent to multiple places from the same switch. For example, you might want to turn on a bathroom light separately from the ceiling fan. To wire a double switch, you’ll need to cut the power, remove the old switch, then feed and connect the wires into the double switch fixture. Though it is not difficult to wire a double switch, careful attention to safety is crucial to prevent injury.

This article only describes installing the switch itself, not rewiring two conjoined feeds that need to be separated. If you are trying to separate two lights that use the same wiring, as opposed to two already separate sources, you will likely need a trained electrician. Steps Removing Old Switches 1 Cut the power to the room you’re working in.

Head to your circuit breaker and turn off the flow of electricity in the room you are working. Usually the correct circuit is labeled, but if it is not you should turn off all the power in order to be safe. You should still wear gloves and grounded, rubber soled shoes in order to be safe while working. Touch the device to the old light switch or any exposed wires to ensure that there is no power coming to the wall. Some contractors will lump certain rooms together when wiring, meaning that a nearby bathroom that you thought was turned off could have several wires hooked up to the bedroom fuse.

Simply touch the end of the detector to the light fixture in several places.

How To Connect Multiple Light Fixtures To One Switch

The essence of the wiring configuration is for one hot feed wire entering the switch box to be split so that it feeds both switches, which in turn feed hot wires in cables that lead out to two separate light fixtures. However, the actual look of the wiring in the box can vary, depending on where the switches are located along the circuit run. Two wall switches mounted in the same wall box can control two light fixtures fed by the same circuit. This overview describes in very basic terms what the wiring looks like in the simplest installation — where the circuit cable first reaches the switch box, then feeds out from there to separate light fixtures “downstream” from the switch box.

The assumption here is that a circuit is being extended from an existing source, such as a receptacle outlet, to feed a double switch that will control two different light fixtures Step 1 Shut Off the Power to the Circuit credit: Bryan Trandem Use a circuit tester to verify that the power is off to the circuit you are working on.

Nose Cone® has been proven to be the most effective frontal aerodynamic treatment available for trucks and trailers of all kinds.

When they are connected, the switch is “on. The actual terminal configuration on a three-way switch depends on the manufacturer. To create lights that operate with two separate switches, the electrician uses two special pieces of equipment in the circuit: Special switches known as three-way switches Special wire that has an extra red insulated wire along with the black and white wires within the sheath A normal switch has two terminals that are either connected or disconnected. A three-way switch has three terminals, and the switch connects the first terminal to either the second or the third terminal, as shown here: You use two three-way switches to control the light, and wire it up as shown below: In this diagram, a normal piece of wire comes from the fuse panel to the first three-way switch.

The black “hot” wire enters the switch on the left. Three-way wire which includes red, black and white wires runs from the switch on the left to the switch on the right, with the white wire carrying ground and the red and black wires carrying the output from terminals in the left switch. Normal sheathed cable runs from the right switch to the light.

Wire cutters Video of the Day Shut off the power running through the circuits that hold the lights or appliances with the breaker switches. The two lights or appliances aren’t necessarily on the same circuit simply because they are in the same room. Tag or lock the breaker box to prevent someone from turning the switches on while you work. Run a hot wire from one or both of the lights or appliances to the electrical wall box if necessary. Use electrical tape to secure the end of the hot wire to a fish tape and push it down the inside of the wall to the electrical box.

Bring the wire in through a knock-out hole in the box. Break off the connecting metal piece between the dark bronze terminals on the double stack switch with a pair of pliers. Stack switch wiring will not work for separate circuits if the two switches remain connected. Loosen the terminal screws on the double stack switch with a Phillips screwdriver. Connect an incoming power wire to the dark bronze terminal on the top switch by wrapping the bare wire around it clockwise and tightening the terminal screw.

Connect the hot wire for the first light or appliance to the brass or silver terminal on the opposite side of the top switch in the same fashion.
