A Switch Board is used to enclose electrical accessories such as switches, sockets, indicators, dimmers, regulators, etc. As the name suggests, it is basically a board of switches and other power control devices. It provides the necessary support and protection from any direct contact of foreign objects.
Switchboards are used primarily to enclose and protect the electrical wiring and the switches from damage. They also prevent accidental human contact with live wires which could lead to electrocution.
