The Curved Edge range has been expanded to include a range of wiring accessories that comply with current Building Regulations Part M.
It is recommended that switches contrast with the front plate which in turn contrast with the wall. This range satisfies both recommendations. With a Light Reflectance Value (LRV) of approx. 8.9 (Part M recommends a contrast of 30% LRF between front plate and wall)
An intermediate switch is used when you have three switches controlling one light. A typical example of this is on a landing. There is a switch at the bottom of the stairs, one at top of the stairs and one at the end of the landing. On this circuit you would need the middle switch to be intermediate (i.e. the one at the top of the stairs) in order for all the switches to function properly.
