Electrical switches are household consumables items. A switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. When the switch is open, the electrical contacts do not touch and electricity cannot flow. When the switch is closed, however, the electrical contacts touch and electricity flows throughout the circuit. In almost every application, for residential, commercial or industrial use, switches are required to be installed. Electrical switches are used to perform all the electrical functions. From a fan to bulb, every electrical equipment we use in our day to day life is useless without a switch.
The types of electrical switches
The different types of Electrical switches which are used for household as well as commercial purposes.
One-way (single pole) Electrical switch:
It is one of the most common use switches. Generally, they are used for light, fans, or other devices from a single location switch. Their simple function is ON and OFF, This is something which is not in any other switch such as in three-way and four-way. A one-way switch generally works as a brake switch. The two terminals of the switch are connected when it is turned ON, and the contact between the two is broken when the switch is turned OFF.
