Knowledge is power, and sometimes "enlightenment" allows us (people) to easily overcome small and large difficulties in life. The topic of this article touches upon a purely everyday question: how to independently install a two-key switch? So let's get started.
Light rule
You will probably agree with the following proposal. Perfectly observed safety precautions allow a person to preserve life and health. Before "contacting" with wires and electrical devices, it is necessary to understand the following. Marginal attention is a fundamental factor in success in such an enterprise. And the two- key plug- in switch in this business is far from an exception. In no case do not neglect security measures, as sometimes absolute confidence can turn into an irreparable mistake. Therefore, before carrying out work with electricity, make sure once again that the house, apartment or other premises are de-energized at the time of work. And only after checking with an indicator or multimeter will show the absence of voltage in the electrical circuit of the object of work, you can safely proceed to the implementation of the connection.
Which two-key switch to choose
Today in the market of electrical goods you can find a lot of various devices that allow you to control the lighting of rooms. The most common are conventional switches, which can have various connection contacts: plug-in or screw type. It will be easier for you to navigate during the installation process, if the two-key switch has a marking indicating the correct connection to the network. It should be noted that the main part of the device, connecting and interrupting the action of current, should reflect the quality of the product. Backlash and gaps between the keys, the difficult movement of the mechanism - these are unacceptable moments in operation. Be careful in the selection process.
Step-by-step instructions for connecting
- We deenergize the power supply of the house (apartment).
- Dismantle the old light switch.
- Bred the ends of the disconnected wires.
- We turn on the electricity and check with an indicator which of the output wires is phase (the LED lights up).
- Disconnect the house (apartment).
- We connect the switch.
- Phase input is indicated by the letter “L”, output contacts are usually labeled “down arrow”.
- We fix the electrical device.
Standard solutions for added comfort
In the event that you need to install a two-key switch with a backlight, the connection principle remains the same. Of course, the practical value of such a device is much more effective, especially when you consider the areas of a house or apartment that are difficult to access for daylight. The basement type rooms are equipped with exactly such breakers, since the active LED significantly facilitates the process of detecting the "necessary" key or lever. Another important element in the organization of comfortable lighting of corridors and hallways is a two- gang switch through passage . The principle of his work is that a person has the opportunity to control the light in one of the rooms from two or more points. Agree, this is very convenient.
Finally
The process of arranging, repairing or remodeling premises is almost always associated with the need for electrical work. So it’s not worth experimenting once again, exposing yourself and your loved ones to danger, it is much easier to solve a pressing problem with the help of a professional.
