The electrical mechanisms are indispensable in any installation of a house, office, etc. The mechanisms can be of several types depending on where the installation is performed.

• Recessed interior mechanisms: Ideal for indoor use.
• Mechanisms of interior in surface: Ideal for the use in interiors without necessity to realize work.
• Exterior mechanisms: Ideal for outdoor use andGarages

Within each type of installation is where we can find different mechanisms depending on the function we need. The most common electrical mechanisms in an electrical installation are:

1. Simple switch: The mechanism that serves to turn the light on or off at one point.
2. Switch: This is the same mechanism above, but this allows to turn the light on or off from two points diIngs.
3. Crossover switch: Same as above but allows turning off and on the light from three different points.
4. Pushbutton: Normally used for timbres or steps with light and on/off timer.
5. Regulator: It allows to control the level of power of light.
6. TV socket TDT/SAT: Connections for TV, radio, and/or satellite connection.
7. Base schuko: TomaCurrent based on neutral, line and ground.
8. Telephone or network socket: Bases for telecommunications, networks or telephone.

Nylon or nylon is a polymer of artificial origin that belongs to the group of polyamides, based on a composition of diamine and diacid chloride.
According to the amount of carbon atoms in the chains of the amine and chloride, it is indicated behind the name, for example, the most common nylon 6.6.

Nylon as it is a very elastic and resistant material is ideal for the textile industry, mainly used foror in the manufacture of stockings in the USA.
Its application was extended until today, where not only do we find nylon in the textile application, but its applications have varied, being able to find this material in utensils, and machinery.
