We showed in a video how to set an alarm for your home, apartment, office, office, business, home or wherever you need quietness and security offered our alarms.

These are two types of contacts widely used in electrical installations and circuits. Distinguishing the difference of these two types is very simple.

• A NO (normally open) type contact is one that does not let the current flow while the same or the device is in standby or standby mode. The most common type NO contact is eg house switches, which remain open (not closedCircuit) until the switch is pressed.
• The NC contacts (normally closed) are the opposite of the NO contact, they let the current pass while they are in standby or at rest to be actuated. An example would be a thermal protection relay of a motor, which remains closed while there is voltage.

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).
