Basics of light switches
Fundamental principles of switch. There are many configurations for wiring connections that two-way, three-way and four-way switches. It is important to understand connection principles than remember the hook-ups. This way you will be able to each installation.
The most important principle is that a neutral wire is never enabled. A switch interrupts the flow of current to an armature, never. The path of the current is always the same: from the source to the switch (es) on the support and then back to the source. All wires leading to the furniture are hot; All wires to the source of the armature are neutral. If you are wiring with cable, do not forget that a cable is a cluster of group activities threads that serve different functions.
Wires must be color coded well. If you are wiring with cable, there are times when you may use the white wire as a hot conductor. In such cases always black and white both ends of the thread to indicate that it is warm. Electrician’s tape or paint. Switches to the correct terminals and cable with the correct number of conductors.
