It is effectively two single gang intermediate switches on one face plate.

2 way intermediate lighting circuit wiring diagram. Remove the existing socket or switch from the wall if replacing. Notice that the wire connected to the COM terminals is looped straight through the intermediate switch using a cable connector. Schematic diagram of new wire colours.

Suppose you want to turn off the bulb top of the staircase from the upper switch above the ladder then switch off the switch then the circuit will break and the bulb will close. Below is the way I like to do it. Connect the blue wire with the brown slewing coming from the light to the L2 terminal together with the 3 CoreEarth cable grey wire.

Three way switching 3 wires. Short video on how to draw a wiring diagram for an intermediate switch. You will have to connect the brown Line wire to the L1 terminal and the blue wire with the Brown slewing on it Switched Line to the L2 terminal.

Each protected by a 5 amp fuse or 6 amp trip in the consumer unit. Connect the blue wire with the brown slewing coming from the light to the L2 terminal together with the 3 CoreEarth cable grey wire. Intermediate switches can be used for 1 and 2 way switching.

Three wires between the two end switches probably using 3 core and earth cable. After this step you will need a length of the 3 Core Earth cable. The circuit consists of a two way switch at each end top and bottom switches in Fig 2 and an intermediate switch in the middle.

Student training aid for the connections required to wire two way and two way and intermediate switching. The diagram shows the common method of wiring an intermediate switch into a two way light switch circuit. This is also known as the conversion method since it is the easiest way to add a second light switch to an existing circuit.

Below is the same diagram Fig 4 to control a light point lamp from three different places by using two two-way switches and one intermediate switch with different symbols. Always ensure that the mains supply has been suitably isolated before commencing installation. PIN1 PIN2 of the first switch are connected with the PIN1 PIN2 of the second switch respectively.

Three way switching old cable colours. All three switches are connected together by a three core and earth control cable. Consider the 2-way switch wiring diagram above that is used to control the bulb in the stairwell.

2-way lighting circuit wiring diagram 2-way lighting layout drawing Intermediate lighting. See below links to various images of wiring diagrams for installing Varilight products. The schematic shows that the circuit is complete and the bulb is on.

In Fig 3 a lamp is controlled from three different places by using two 2-way switches and one intermediate switch. This is the first method to make a 2-way switching connection this is the old method. All metal faceplates must be earthed.

3 way light switching new cable colours 3 way light switch old cable colours 3 way light switch. If you are going to install a new one then go for three wire control methods. A single 56 amp circuit can cope with up to twelve 100 watt lamps it is usual in a multi-storey house to have at least one lighting circuit for each floor even if the number of lamps are less than 12 on each level.

Connect the Line brown wire coming from the light together with the 3 CoreEarth cable black wire in to the L1 terminal of the two-way switch. The cable coming from the light to the first two-way switch is where you need to continue. Old multi-point radial lighting diagram using junction boxes.

Connect the Line brown wire coming from the light together with the 3 CoreEarth cable black wire in to the L1 terminal of the two-way switch. 2-way Switch Wiring using Two-wire control. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate.

Staircase Wiring using Intermediate Switch. Intermediate switch wiring diagram new cable colours The intermediate light switch is used where three or more switches control one light and used in conjunction with two two way light switches to achieve this. A two way switchuk Schematic diagram of old wire colours.

This allows a single light to be turned on or off from any of the switchesThis page shows it wired in the new cable colours if your house has the old colours you want to go here. The way I show allows you to fairly easily add a second two way switch to an existing light switch by simply wiring them together in a certain way. Touch dimmer diagrams are for the following ranges- V-Pro IR V-Pro Multi-Point Touch and Remote and V-Pro Eclique2.

2 way light switch 3 wire system new harmonised cable colours 2 way switch 3 wire system old cable colours 2 way switch two wire control Three way switching. Two way light switching schematic using a two wire control Downside s of the two wire control system. You are most likely to see this 2 way lighting circuit in an industrialcommercial setting where the installation is trunkingconduit based and single core conductors are used.

Usually the third wire passes the middle intermediate switch but is joined in a separate terminal block. For multiple gangs repeat wiring where necessary. As you see in the 2 way switch diagram below you will find that the phaselive is connected with the common of the first 2-way switch.

Four pages showing how 3-plate lighting circuits can be wired up. There are several ways to wire two way switching.
