A switch is a component of an electric circuit that makes or breaks the circuit, turning the components on and off. Here is a diagram of a circuit with a switch in it. Switches do not all look the exact same, and they can be drawn in a number of different ways.

A switch is a component which controls the open-ness or closed-ness of an electric circuit. They allow control over current flow in a circuit (without having to actually get in there and manually cut or splice the wires).

2016年9月1日 · Switches are very simple components essential in your electronics circuits. A switch can: act as an interrupter, interrupting the electric current. In the example in the figure below, the switch is either interrupting the current to flow and the LED doesn’t turn on, or it allows the electric flow and the LED turns on.

2024年5月21日 · Electric switch responds to an external force to mechanically change an electric signal. Electric switches are used to turn electric circuits ON and OFF and to switch electric circuits. The main function of an electric switch is to regulate the current between the load and source of power.

2025年1月14日 · A switch is an electrical component that can create or break an electrical circuit automatically (or) manually. The switch is mostly used with an ON (open) & OFF (closed) mechanism. Many circuits contain switches that affect how the circuit functions or activate certain circuit properties.

2025年1月1日 · A switch is an electrical component that connects or disconnects the conducting path in an electrical circuit. A switch is made up of electrical contacts. When the contacts are touching they allow current to pass through them and when they are separated no current can pass through them.

2023年8月21日 · The three main functions of a switch are to open or close an electrical circuit, control the speed of a motorised device, and limit the amount of current flowing through a circuit. Switches come in different sizes and ratings to handle different loads, so make sure you choose the right switch for your circuit.

An electric switch is an electrical component that breaks or closes an electric circuit. Opening the switch (breaking the circuit) means turning off the electrical device and closing the switch (completing the circuit) allows an electrical current to flow so that the device is on.

Switches work as you would expect! Current can flow through a closed switch, but not through an open switch. If closing a switch creates a complete circuit, then any components (such as light bulbs) within this complete circuit are ‘switched on’. As useful as electronics are, you don't necessarily want them on all the time.
