A LIGHT POINT CONTROLLED FROM DIFFERENT PLACES

1. A point of light controlled from a place by a switch or pushbutton.

To control a point of light from a switch and a button we will need:

1 lamp holder; 1 bulb; 1 pushbutton; 1 switch; 1 circuit breaker; Phase wires, either black, grey or brown; A protective shield / ground wire and neutral / blue wire.

2. A point of light controlled by two different places.

For this practice we will need:

1 lamp holder; 1 light bulb; 2 simple switches; 1 crossover switch; 1,5 cm line conductor that can be brown, black or grey; 1,5 cm neutral blue conductor; 1,5 cm PE conductor yellow and green; Automatic 10A.

3.A point of light controlled from three different points (commutator-crossover switch-commutator).

To control a light from three different places we need the following materials:

2 simple switches; 2 crossover switches; 1 lamp holder; 1 bulb; 1 magnetothermic;

Phase cables (black, grey and brown); Neutral wire; Ground wire.

Commutator:It is an element that consists of an input (the phase) and two outputs.

 

4.A point of light controlled from four different switches or places. 

 Here it is a simple scheme,elements and connections needed for our

 installation:

The scheme

List of materials or elements required for our installation:

2 simple commutators; 2 crossing commutators; 1 electric bulb; 3 different colours of Cables of (1.5mm); 1 magnetothermic of C10A; 1 bulb holder.
