LED dimmer module has auto-detect function for either leading edge or trailing edge with 5-150W load, 230-240V 50Hz In accordance to the Building Regulations and the BS 7671 wiring regulations, if you are simply exchanging an existing standard 1 or 2 gang light switch for a dimmer switch then this is entirely possible to do on a DIY basis, as long as you have the knowledge to do so. Modern dimmer switches use this cycle to determine when to turn the light off. At the point that the switch from positive to negative happens there will be zero voltage and this is when the switch cuts the power. For more information on staying safe when working around electricity, see our electrical safety project here. What is a Dimmer Switch? For the purpose of this project we will be swapping and existing 1 gang 1 way switch for a similar 1 gang 1 way dimmer switch. Step 1 – Isolate Circuit

Adding a dimmer switch to the lighting in a room can have a dramatic effect on the overall ambience of a room, allowing you to lower the lighting levels to create a much more relaxed environment. Today, modern dimmer switches are much more efficient and instead of using a resistor, essentially turns the light on and off very rapidly every second. As both UK and US electricity is AC (alternating current) it turns from positive to negative every cycle.However, if it is to be a newly installed switch where all wires and cabling needs to be run from scratch then this is not possible to do as a DIY’er and can only be done by a Part P registered electrician with the knowledge and skill to do the work correctly, test it fully and then issue a minor works certificate.

If you have a metal face plate for your switch there should also be a green and yellow earth wire to a small terminal on this. If not then it should be connected to the metal box in the wall called a pattress box. If the pattress box is plastic then it should be screwed into the earth terminal somewhere inside.

If the new dimmer switch has a metal faceplate then you will also need to connect the earth to the earth terminal on the faceplate. Aside from the main differences in how they operate, dimmer switches are also available in several different operation: To release each wire on the switch, use your flat blade screwdriver to loosen the small screw in each terminal and then pull the wires free. If the earth is also fixed to the faceplate, unscrew this, if attached to the pattress box leave it where it is. The very first job to do before doing anything else is to isolate the circuit you will be working on by turning off the MCB/RCD in your consumer unit or pulling out the fuse if you have a fuse box.
