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.
Switchboards are one of the most commonly-used devices in household power connections. They are used as a single-point location for turning appliances, devices, and connections on or off.
Switchboards are used to make inexpensive DIY extension boards as well. This helps to avoid the cost of buying a new extension board. Many students use it for academic and scientific projects because these are much more customizable than ready-made extension boards. You can find several articles and videos on the internet that are specially created on “how to make an extension board yourself”.
