An electric switch is a device that interrupts the electron flow in a circuit. Switches are primarily binary devices: either fully on or off and light switches have a simple design. When the switch is turned off, the circuit breaks and the power flow is interrupted. Circuits consist of a source of power and load. A load is a power-powered device. The function of an electric switch is to regulate the current between the load and source of power. The power source is the electrons that push through the circuits. The voltage is the quantity of force or pressure applied by the power source. Power sources must have a negative and positive endpoint.  The negative terminal connects to the charge, and the electrons drive through the circuit. The load receives the current and returns it via the positive terminal to the power source. The electrical switch is inserted in this loop.




Electrical switches work according to a basic design. The most common switches are the on/off toggle ones. Three-way and dimmer circuits are similar in design. Three-way circuits consist of two separate switches that control the same device, while a dimmer circuit controls only the amount of electricity that passes. Electric circuits work when electricity can move in a continuous loop. The electricity cuts off once the circle is broken. This is where the switch comes in. A toggle on/off circuit breaks the current when it is off. The current or loop completes itself when it’s in ” on ” position.




Fusebox is the power source in a home. For an electric switch to work, it must be connected to the fuse box and the load. A specific cable type is used to connect the power source to the switch and the power outlet that drives the load. There are three wires, a hot wire, a neutral wire and a ground wire within this insulated cable.

  1. Hotwire connects to one of the terminals on the switch and the load-powering outlet.
  2. The neutral wire links the other terminal to the load.
  3. The ground wire connects to the outlet.

Electrical contacts inside the switch join the two terminals together. The connections link when you turn on the switch. As the switch is turned off, these contacts break. The current is controlled by the position in which the switch is located.


There are different types of switches such as toggle switches, joystick switches, pushbutton switch are a few of them. Toggle switches and pushbutton switches are common light switches used in a household. Finolex cables-make Finoswitch has a range of switches made of superior quality. They are durable and tested to last over 1,00,0000 clicks and have a fluorescent strip that glows in the dark and acts like a guide. Purchasing good quality products is always beneficial in the long run.
