What is a Toggle Switch? – 2023 Types & Applications with Pictures


toggle switch is an excellent electrical button or switches used to turn on the electricity in the electric circuit. Electric current can pass in the circuit if the switch is on; otherwise, current cannot pass through the circuit. As we know, a toggle switch is a power-driven tool that can easily be wrought with one hand. Also, these toggle switches are available in various styles, such as: 

  • Single Pole
  • Double Pole 
  • Three Pole 
Single Pole, Double Pole, Three Pole                   toggle switch

Many consumers can’t understand the main functions of the toggle switch, and some others do not know much about” what is a toggle switch?” we describe the answer to this question. Toggle switches primarily regulate electrical lights and other mechanical/ electrical appliances. They are used to control all procedures we perform through an electrical circuit; these toggles are available in different qualities that meet the tool’s requirements and easily configure in any plant.

Basic Types of Toggle Switches in 2023

Switch types depend on the linking of the electrical circuit that can regulate the entire procedure of electricity. There we describe the main components that are helpful to create a meaningful and better circuit of electricity and elaborate on the connection of a switch we needed. Two components are played a primary role in constructing the valuable placements of toggle switches and connectivity of circuits.

  • Poles: 

Poles are the central part of an electrical circuit when we control the integer of circuits with the help of a switch called a pole.

  • Single Throw:

A throw switch comprises one or two pairs of connections that may be closed or opened.

  • Double Throw:

A double-throw switch comprises two or other pairs of connections. When the switch is “ON,” the current easily flows from both terminals, but if the connection is on “OFF MODE,” the current flow can’t pass through both terminals of the switch.

Here, we discussed the main types and configurations of switches. Keep reading!

Switches can be defined by their specifications and other paramount quality of connectivity. But these below mentioned some times are very crucial for the electric circuit.

  • SPST (Single Pole Single throw)
  • SPDT (single pole double throw)
  • DPST (double pole, single throw)
  • DPDT (double pole double throw)

SPST (Single Pole Single Throw)

The SPST is a primary ‘’ON’’ and ‘’OFF’’ button/ switch, mainly used for disconnecting the main link of two terminals. For the owl circuit, it’ll provide the power supply. Here, we add the SPST toggle for your ease, and it’s one of the most prominent switches or toggles that’ll help to control the flow of current in the circuit.


In other words, the SPST switch is a toggle switch displayed below, and this type of switch represents one output or input. This light switch can make a single light connection and control a single circuit. If we ‘’ON’’ or close the circuit with the help of a switch, the current flow in the whole circuit, and we see the blinking of the bulb, but when the switch is ‘’OFF’’ or opens the circuit, then the flow of current stopped in both terminals that are attached.

SPDT (Single Pole Double Throw)

SPDT switch has three terminals, but for input, only one terminal is used; the remaining terminals are cast-off as outputs. It also offers the joining of one terminal to additional two depots. Instead of the various terminals, SPDT is one of these terminals that have a COM terminal; either we also use COM & A or COM &B in it.


This application is known as the SPDT which that is basically tangled in three- way circuit. For turning ON/OFF a light in whole circuit from top to end of a flight of steps. Here we explained the all SPDT procedure through a picture and we mentioned below some simple steps. Read carefully!

  • If we close switch A, you can see the flowing current in the terminal 
  • Switch A closed, Light A blinks, and Light B will ‘’OFF.’’
  • If you did it with switch B and done the whole procedure, then Light B blinks, and light A will be ‘’OFF.’’
  • With this, we can control the whole circuit with one source

DPDT (Double Pole Double Throw)

This switch system is considered the same as two SPDT switches; in this whole circuit, basically, two separate circuits are present with two connecting inputs and in the rotation, we’ll see each circuit attach one of both/ two outputs. With the help of a switch position, we can easily route every contact and recognize the connection ways.


When the switch is in ON-ON mode or 0N-OFF-ON mode, it’ll work on the two basic isolated buttons that work as the same actuator. At the same time, only two piles can be ‘’ON’’. A DPDT switch is the only one that can be used in any mechanism or application that is needed as open and closed in the typical wiring system.

How Does A Toggle Switch Work?

These toggles are available in various designs, frames, and configurations, but these toggle switches are made under these fundamental laws. When we pull the attached armature, we place an electrical exchange into a circuit or eliminate it; now, it’s your choice what you would like.

The switch remains stable until it changes again, but on the contrary side, all the momentary switches are also attached to the spring, which will help the actuator back to its accurate position when it is released.

Toggle Switch Accessories:

Accessories of toggle switches are available with different qualities and configurations, but accessories make them more efficient with variable attributes. Here, we mentioned some accessories of toggle switches. Keep reading!

Switch Guards

These toggle switch guards are primarily used for the protection of the switch and also save the sudden on/ off switch with the hard casing of the toggle. The toggle switch casing is a great source to prevent us from bare wires.

Rocker Switch Vs Toggle

There are two main types for the toggle maintenance.

  1. Rocker
  2. Toggle switch
Toggle switchRocker Switch
Toggle switches are used explicitly for circuit boards, and we’ve found them too easy to seal because it’s the best resistance to liquid, moisture, and dust. It’ll make it more variable and perfect for the harsh atmosphere.  The rocker is used for the professional look and customization of the switch; it also improves the rocker’s best qualities, such as icons, symbols, and text. It is also used for communicating functions where the prerequisite and needs of this switch are.     
  Rocker Switch Vs Toggle                                  

The different variables are considered before using the rocker and switch; design and conditions tell us which one is better for your project. It depends on the user; some prefer the appearance of a toggle, some prefer universal, or some desire the handsome appearance of a rocker witch. But on the contrary, side, if the products are selected for the marine industry, we suggest the toggle switch for better results and security.

How To Wire A Toggle Switch

A toggle switch is a modest yet actual way to control electrical circuits. It is a switch that can be easily turned ‘’ON’’ and ‘’OFF’’ with a finger’s flick. These are used in a variety of applications, including:

  1. Electronic devices
  2. Automotive electronic
  3. Industrial machinery

Toggle Switch Working Principle

A toggle switch is an electrical switch activated by simply pressing a button, flipping a lever, or moving a switch up or down. It is one of the most common switches used in electronic devices. This is an ON/OFF button that can access the movement of voltage in a circuit.

When the toggle button is in the ‘’ON’’ location, it finalizes the route and allows energy to flow. When the switch is in the ‘’OFF’’ position, it create the discontinuities in the circuit and excludes voltage from flowing. The toggle switch can control devices, including lights, fans, and computers. The toggle switch is a very adaptable and reliable switch that can be used in various applications.

What is Toggle Switch on iPhone?

Do Toggle Switches Need Grounding?

These are a collective switch type used in many applications, including automotive and industrial settings. They are typically made from metal or plastic, consisting of a lever flipped up or down to make or break the connection. Toggle switches can be either momentary or maintained, meaning they can either stay in the on position after being activated or revert to work once released.

Some toggle switches also have a third position between the on and off jobs, known as the middle, neutral, or spring-return position. So, do toggle switches need grounding? The answer is yes and no. If the toggle switch is being used in an application with a risk of shock, then it must be properly grounded.

Features Of Toggle Switch

A toggle switch is an electrical switch typically used to operate a light, machine, or device. It is characterized by a lever that can be moved up or down or back and forth to make or break the connection in the circuit. Toggle switches are accessible in many altered styles and configurations and are used in inhabited and profitable applications.

These toggle switches are presented in numerous sizes, shapes and colours. They can be single poles or double poles and can be organized for either momentary or sustained procedure. Most toggle switches have an illuminated tip that glows when the button is in the on position, making them easy to locate in the dark.

These buttons are relatively simple devices, but they offer a wide range of features and options that make them suitable for various applications.

Three-position toggle switch on-off-on

A toggle switch is a device that can be used to turn things on and off. There are three types of toggle switches:

  1. on-off-on
  2. on-off-on-off
  3. on-off

The most famous type of these toggle switches are the on-off-on switch. This type of switch has three terminals, one for each button position.

  • When the regulator is in the “on” position, the runs flows from the first terminal to the second terminal.
  • When the button is in the “off” position, the current runs from the first terminal to the third terminal.
  • When the switch is in the “on” position, it can be used to governor two diverse circuits.

How Does A 2 Way Toggle Switch Work?

A toggle switch is a button that a lever or other moving part can operate. The most common type of toggle switch is the:

  • Single-pole
  • Double-throw (SPDT) switch

The switch attaches the top terminal to the bottom terminal when the lever is up. The button connects the base terminal to the top terminal when the lever is down. Thus, an SPDT toggle button can be used to attach or detach two paths.

Frequently Asked Questions (FAQs)

How to install a toggle switch for lights?

A toggle switch is a switch that is controlled by a lever or handles, and it can be used to turn something on or off. Toggle switches are often used in electronics and can be found in many devices, from computers to lamps.

How to wire a toggle switch to a motor?

A toggle button is an electrical switch characteristically used to controller a circuit. Toggle switches are available in various styles, including momentary, maintained, and locked.

  • To wire a toggle switch to a motor, the first thing to do is to identify the terminal locations on the button. The terminals on a toggle switch are typically labelled “COM,” “NC,” and “NO.” The COM terminal is the common terminal, while the NC and NO terminals are the normally closed and open terminals.
  • Next, use wire strippers to band about 1/2 inch of lagging from the expiration of each wire attached to the toggle switch. Once the cords are stripped, use a screwdriver to untie the screws on the toggle switch so that you can addition the wires into the terminuses.

Toggle switches are commonly used to turn lights and appliances on and off, but they can also control other devices, such as fans, pumps, and solenoids.


At last, we can conclude a toggle switch is a manually operated button by a projecting lever, handle, or thumb. It is often used to rheostat a circuit by disturbing the current run. Toggle switches are vacant in many different styles and sizes and can be used for numerous applications.
