Hire a licensed electrician. DIY electrical work appears to be illegal in Israel.
According to the Israeli Ministry of Labor and Social Affairs, it is illegal for individuals who are not licensed electricians to perform electrical work.
The Law in the State of Israel prescribes that whoever engages in the performance of electrical works must hold a valid electricity license appropriate for the class of electrical work. The performance of electrical works by whoever is not in possession of a license constitutes a criminal offense.
Presently, the Electricity Law defines "the Performance of Electrical Works" as the installation, inspection, change, repair or dismantling of an electrical facility including supervision of the performance of works as aforesaid and the drafting of technical plans for the performance thereof.
I'm not a lawyer, but that sounds like it includes DIY work on your own home. As a result, if you perform the course of action you're asking about in this question, you will be performing a criminal activity.
There are good reasons for this; electricity is dangerous and you mess around with it, you risk killing people, burning down your home, or both at the same time. If you want electrical work done, hire the services of someone who has been trained in how to do it safely.
