It will be connected to the face plate screws so that they are earthed and will not carry a current. Bridge This will either sit inside the wall, in the plaster or cut into the plaster board, or be mounted on top of the surface of the wall. Plastic tends to be used if the pattress is surface-mounted and metal when it is incorporated in the wall.

Compatibility - 3 gang switches are compatible with most electronic components with a voltage rating of 230 volts and a current rating of 13 A. Face plates have the terminals fixed to it which are usually screwed. The live and neutral are 22mm apart. To prevent something accidentally being inserted into the live parts of the plug, there are shutters (UK plugs) which only open if the top, earth ping is inserted. There are holes or “blinds” where holes can easily be made, so that the cable can enter the box (see grommets below). They come in a range of depths, so it is important to ensure that when changing a face plate that the new one will fit. The width will be determined by the number of gangs or plugs that can be plugged in at once. Face Plate This is the metal strip that connects the earth terminal and therefore earth wire to the face plate screws. Terminals Terminals – These provide the entry points for the wires to be connected to either side of the switch. The switch will interrupt the flow of electricity through the live (Brown sheathed) wire.This is the uPVC sheath containing the electrical wires, Live, Neutral and Earth. Previously the sheath was made of rubber and these cable should be changed by a qualified electrician – find one near you here. Live As we are dealing with electricity it is obligatory that we warn you about safety. We have a great project that helps you understand what you are allowed to do, what you cannot do and what are your obligations under the Building Regulations (Part P); Find out more about the electrical do’s and don’ts here. It is designed to protect the cable from becoming damaged by the box, and the cable should also be tight fit so that if there is a fire in the box it will not spread easily. Cable

Pattress – This is the box that contains the parts of the light switch. Make sure that you get the right size face plate to fit on the pattress that you have fitted Feature inherent anti-microbial properties and are tested for resistance to different strains of bacteria such as MRSA, E. Coli, Salmonella, and Klebsiella Pneumoniae.
