Once you have a look at cable gland manufacturer or possibly a light switch, the amount of control points will it have? If it’s a double socket, it’s 2 gang, single socket is 1 gang. Same goes with a mild switch, whether it has one switch, it’s 1 gang, two switches, 2 gang etc.
This is a term for a way the switch works. A 1 way switch simply breaks the circuit when thrown, it only has one live terminal. A 2 way switches the live connection from one terminal to another one, letting it be associated with another 2 way switch, controlling one light from two positions.
Double pole can be a safety feature on mains electrical control points that breaks the connection of both the live and neutral terminals giving complete isolation, making it possible for maintenance on powerful appliances.
An intermediate switch is made for when you need to manipulate a mild from three positions. Imagine you have a landing light that should be controlled from two ends from the landing and the bottom of the steps, the switch in the middle of this circuit would be an intermediate.
There is a lot more choice than the bog standard flexible conduit fittings plastic that adorn many thousands of walls across the land. Many metal finishes can be found, a number of the more widespread ones are;
Brushed Stainless Steel
Painted White Metal (in gloss or matt)
All metal finishes can be purchased in slim plate depths, from 5mm to super slim 1.5mm and with or without visible screws. It really is worth noting that these particular slim plates won’t fit in anything shallower when compared to a 35mm deep backbox.
You can find new UK regulations signing up to new build properties concerning the position of stainless steel flex conduit. All power sockets needs to be fitted at the very least 450mm from the floor, while light switches cab1e be no greater than 1200mm in the floor. All points must also be a minimum of 350mm through the corner of any room. This really is allowing for simplicity of use by individuals with a disability or wheelchair users. It is also advised the sockets has to be placed around 100m from the working surface to allow sufficient room without causing problems for hanging flex.
