Because the electrical code as of the 2011 NEC update requires a neutral wire in most new switch boxes, a 3-wire cable runs between the light and switch. This is an overview of how to wire a one-gang light switch on a one-way circuit: Switched Live Wire (SW) connects to L1 port Common Live Wire (CW) connects to Common port Earth Wire connects to switch plate/back box Earth ports (Multi-gang switches … Two way switches have a COM terminal as well as L1 and L2 terminals. Cable D (Fig 2) is a three core and earth, this is the ‘3 wire control’ that links the two light switches together. Jan 24, 18 02:09 PM The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer, remote control, or other programmable switch. How to wire 2 way light switch, in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches. Common Live You can use a two way switch for one way switching. The tilde with the arrow through it symbolizes the adjusted AC. OLD COLOUR Now you can operate the light either on or off from either switch. These are typically labelled COM, L1, and L2 (Some may label the L1 and L2 positions as "1 Way" and "2 Way"). The yellow/green is earth but not on new plastic switch and can connect onto the back metal box. L1 and L2 Motor Wiring The L symbol designation refers to the Line, or the incoming circuit wires that provide the power for the motor. Where BOTH the back box and the switch plate are metal, first connect the Earth wire to the Earth terminal in the metal back box, and use a separate piece of wire to connect the Earth terminal on the metal switch plate to the Earth terminal on the metal back box. Basically is the existing blue wire essentially a "switched live" like the instructions talk about or do I need a different type of switch to work with the old wiring? Unscrew the switch plate, pull it towards you slowly and examine how many wires are present and what colour they are. Green & Yellow. The first method as shown in the figure above have the COM, L1 and L2 of both the SPDT switches connected together. L1 L2 Com Wiring Diagram – wiring diagram is a simplified suitable pictorial representation of an electrical circuit. There was a seperate loose red wire that went into both COM's. If you are aware that the light switch was functioning correctly prior to replacing the switch plate, simply note the layout of the wires and copy the wiring layout in the replacement switch plate.). This is the HOT OUT (the dimmed output). All Rights Reserved. Sometimes it is handy to have an outlet controlled by a switch. These are typically labelled COM, L1, and L2 (Some may label the L1 and L2 positions as "1 Way" and "2 Way"). This is an updated version of the first arrangement. Wiring a Two Way Switch Two way switching means you can switch the same light fixture from two switches that are located in different sides of a room. So simply remove the wiring from the side that is currently switching the landing switch and replicate it in the side that is currently switching the loft light, i.e. In the other position, COM and L2 are connected. In this picture, you can see the strip gauge on the back of the switch. Using a wire stripper, remove up to ½ inch of the wiring insulation, exposing the wire beneath. When the switch is on, both terminals are connected together. Move all wires fitted to C to the L terminal on the Lightwave switch. If you look inside an existing wired in two way switch you will see quite a few wires of differing colours. We look at the EU colour coding wires and explain the different ways to connect the lighting circuit. In the other switch position it changes over so that COM is connected to L2. These have four terminals and are equivalent to two 2-way switches combined. 120V 240V Electricity explained - Split phase 3 wire, Convert Sea Water to Fresh Water, Why we need to - isave filter salt water, Bamboo is the Best Alternative to Steel Reinforcement, How to derive formula for super elevation of road bending. As I have already mentioned in the introduction paragraph, a two way switch is very useful in staircase lighting as you can turn on the light just before you start to climb the stairs and once you reach upstairs, you can turn off the light simply by toggling the switch placed near the top of the staircase. Jan 24, 18 02:26 PM. Want to turn a lamp on with a light switch? NEW COLOUR COM on the first switch connects to COM on the second switch, L1 on the first switch connects to L1 on the second, and L2 on the first switch connects to L2 on the second. © 2021 Supreme Imports Ltd T/A LED Hut, Registered in England and Wales under number 05292196, How to wire 2 way light switch, in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches. A two way switch has 3 terminals. Earth First, let’s recap the colours used to identify the Common Live wire, the Switched Live wire, and the Earth wire: WIRE TYPE Where should the live and neutral wires go? Step by step instructions on how to wire a switched outlet. You use L1 and L2 to control light from 2 switches as in head and foot of staircase. For added safety, use a voltage tester to ensure that the circuit is not live and there is no power to the switch. Now that you'er familiar with some of the wires you'll be identifying, you can figure out which wire is which based on the type of switch you have installed. The new switch has connectors marked COM , L1 and L2 and an earthing point. The wiring in just one feed, red is providing the live feed in and black is routing back to the rose to the connection with the light fitting wire … When installing the Brilliant Control in 3-way configurations, the traveler wires will be installed in the wire holes labelled “L1” and “L2”. A metal light switch must be earthed as seen below. When L1 is off L2 would be on. Registered office at 4 Beacon Road, Trafford Park, Manchester, United Kingdom, M17 1AF - VAT NO : GB 927 173 808. This gauge is when you want to use the "quick-connect" method when wiring a light switch. An extension of the one way switch, this has three terminals. L1 and COM is used on your old switch and you have those 2 connectors on your new switch. fig 3 . They will be marked so you can tell which is which. Black/Red It is just a single switch light, so is it as simple as RED into COM, BLUE into L1, ignore L2 and EARTH to EARTH terminal. There are various labelling schemes but L1, L2, L3, L4 is common. There are a couple of ways in which you can make a two-way switch connection. Two way light switch mechanism In position 1 (when the switch is down or ‘on’), COM and L1 are connected together (just like the one way switch). My new switch doesnt have a COM, just L, L1, L2. Connect the "source" wire to the bottom terminal of the switch and the other black wire to the top terminal. The first priority is to ascertain which lighting circuit the new switch is going to be installed on and switch off the power supply. T1 T2 T3 T4 T5 Motor Lead Wires The (L2) terminal is unused. Red Modern switches typically come in two varieties. When dealing with both a plastic switch plate and plastic back box, the Earth wire may be terminated inside the wire’s protective insulation sleeve and folded over. To wire a light switch, consider whether the circuit is ‘one-way’ (one light switch operating one light) or ‘two-way’ (two light switches operating the same light). *Earth terminals are only present in metal switch plates and metal back boxes (i.e. Brown Earth terminals are not found on plastic switch plates and plastic back boxes). It shows the components of the circuit as simplified shapes, and the capability and signal links along with the devices. Move all wires fitted to L2 to the X terminal on the Lightwave switch. On the first switch COM is the hot leg (typically the black wire), L1 connects to L1 on the second switch, and L2 goes to L2 on the second switch as well. If you are aware that a light may be controlled from two locations (e.g. There are 3 brown wires coming out of the wall and I have a 2-way switch (L1-L2-COM) which operates one central pendant light fitting. The old switch had 2xL1's and 2x L2's 2xCOM's. If the back box or the switch plate is made of metal, connect the Earth wire to the Earth wire terminal. A Two Way light switch is a simple single pole "changeover" switch with three terminals. Make sure mains is off from consumer unit before doing the work. At the first switch, move all wires fitted to L1 to the L terminal on the Lightwave switch. Intermediate. A black wire (with a red sleeve) screwed to "L1" There was also an L2 with nothing screwed into it; The instructions for the new light stated for a 1 way switch with 3 wires: one wire should go to a simalar point near the rim of the fitting (which I attached the green and yellow to, as it was before), 1) The switch wiring needs swapping to 'move' the landing light to the correct position.

Get 5% off your first order - Code: first5, 4 Beacon RoadTrafford Park, Manchester, M17 1AF. Used where two switches control the same lighting. Assuming that that there is no existing light switch from which the wiring layout may be copied, we must understand which wire fits into which port based on the colour of the wires and the labels located next to each wire port on the reverse of the switch plate. now the new switches have a COM, L1, L2 and Earth. A light switch in my bedroom came loose when I was painting around it and I can't figure out how to wire it back correctly. This is the most common type of switch, and is used where a light is controlled from a single switch. A two way switch (for switching a light from two different locations like in a hallway) has a common (C) a L1 and an L2 terminal. (Tip: the plate will be attached to up to three wires. A common(C), L1 and L2. The light connects to COM on the second switch and the other side of the light goes to neutral (typically the white wire). ...plus receive more exclusive offers and product updates. For example: L1 and L2 … Im changing my light switches.... its a 2 button switch and the wires coming out of the wall are 2 cables each with 1 red wire and 1 back so 4 in total plus earth's. For increased reliability, we recommend using the screw variety of switch plate. This can be confusing. The L1 is the switched live going out to the light. Top 10 Tallest Buildings In The World In 2020 - No Towers In America! There is never a connection betweeen L1 and L2. I'm not quite clear which is 'COM' here. Typically, these terminals will be marked COM and L1, or sometimes L1 and L2. Move all wires fitted to C to the X terminal on the Lightwave switch. L1 and L2 Motor Wiring The L symbol designation refers to the Line, or the incoming circuit wires that provide the power for the motor. At the second switch move all wires fitted to L1 to the L terminal on the Lightwave switch. Read More. One is an older method, which is not often used now-a-day… A Two Way light switch is a simple single pole "changeover" switch with three terminals. If you notice any copyright material please contact us immediately at DMCA form and point out its URL. Logic would say that the 2 wires should go in COM and L1 or L2, but the problem is both wires are the same colour, and there aren't any COM or L markings on the back of the old switch. The switch has only L1 and L2 terminals (L3 is 'dummy' with no connection). This is an overview of how to wire a one-gang light switch on a one-way circuit: First, we must identify a one-way light switch. A two way light switch can also be used in in place of a one way light switch, in this instance the red wire from the feed cable is connected to the common (C) terminal and the red wire going to the light is connected to the (L1) terminal. There are no markings on the back of the dimmer switch, and on the back of the new switch I've got 3 points -COM, L1 and L2. Blue In addition, the light switch will either be 'one-gang' (one switch on the plate) or 'two-gang' (two switches on the plate) or higher.
