In the case of a terminal or other device with IP44 format would result. 4 - The element to be used for the test (sphere of 1 mm in diameter) must not come at all. 4 - Do not enter the water thrown from any angle to an average of 10 liters per minute and a pressure of 80-100kN/m for a time not less than 5 minutes.

hen we talk about IP code (International Protection) we talk about an international standard (IEC 60529) which classifies the protection against external factors, solid or liquid, that has a component or electronic device; LED strips, controllers, meters, security cameras, etc.

This alpha-numerically standard has been designed to sort different levels of protection. Nomenclature starts with IP followed by two numeric values.

- Example IP68:

The first value ranges from 0 to 6 and indicates the protection against solid agents. In this case, strong protection against dust.

The second value is between 0 and 8 and indicates the protection against liquid agents. In this case the complete and prolonged immersion during the time specified by the manufacturer.

We could say that the larger the number is greater IP protection has a device.

In below table, we can see different IP protections levels available.

IPXX	First digit (IPxx)	Second digit (IPxx)
0	Unprotected.	Unprotected.
1	Protection against objects of> 50 mm diameter.	Protection against vertically dripping water.
2	Protection against objects of> 12.5 mm diameter.	Protection against inclined drip water up to 15°.
3	Protection against objects of> 2 mm in diameter.	Protection against water projected from any direction, up to 60°.
4	Protection against objects of> 1 mm in diameter.	Protection against splashing water any direction.
5	Ingress of dust is not entirely revented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment .	Protection against water jets.
6	Dust tight.	Protection against strong jets of water.
7		Protection against complete immersion up to 1 meter for 30 minutes.
8		Protection against complete and prolonged immersion.

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.

ABS material (acrylonitrile butadiene styrene) is a type of thermoplastic that is very resistant to impact or shock.

Its applications are several, for example is a material widely used in the manufacture of interiors or components of cars such as moldings, as well as in products for domestic use such as toys, tools, housings of electrical devices etc.

One of its most important characteristics is its great tenacidad in almost all types of temperatures.

Being a very hard material has good chemical resistance, low water absorption and high resistance to abrasion, where other types of plastics would be more brittle.

This type of material is becoming very famous in the particular field and widely used due to the great growth in the sales of domestic 3D printers, the main printing raw material.next to the PLA.

Identification of ABS
Parts that are made of ABS material must be marked in accordance with ISO 11469 (DIN 58840).
