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.

An intermediate switch can be used as a one way or two way switch (but is more expensive, so would not normally be used for this). To be used where there are three or more switches controlling the same light or set of lights, usually where one switch is a dimmer. The most typical example of this might be in a hallway, when perhaps there is a switch at the front door, a switch at the bottom of the stairs and one at the top of the stairs, all controlling the same hall light. On this circuit the middle switch (usually the one at the bottom of the stairs) will be an intermediate switch. This can be extended to four or more switches. The end two light switches need to be two way light switches. All the other switches (in between) need to be intermediate light switches. The Hierarchy of SwitchesGrid switches can be used to create combinations too. You may want to have a two way switch and an intermediate switch on the same plate. This can be created by attaching a two way switch module and an intermediate switch module to a grid frame. Intermediate Dimmer Switch
