What is a Toggle Switch? Types & Applications (Guide)
Many consumers may not understand the main functions of a toggle switch or may not know what a toggle switch is. To answer this question, toggle switches primarily control electrical lights and other mechanical/electrical appliances.
Toggle switches are used to control various processes performed through an electrical circuit. These switches are available in different qualities to meet the requirements of the tool and can be easily configured in any setup.
What Is a Toggle Switch?
A toggle switch is a simple on/off switch that has a lever that can be moved to either the on or off position. It’s an electrical button or switch used to control the flow of electricity through an electric circuit. When the switch is on, electric current can pass through the circuit; otherwise, current cannot pass through the circuit.
As we know, a toggle switch is a power-driven tool that can easily be operated with one hand. Also, these toggle switches are available in various types, such as:
- Single Pole
- Double Pole
- Three Pole
Toggle switches are commonly used in applications where a simple on/off control is required, such as lights, fans, and appliances.
Toggle switches have a variety of properties that make them useful for a variety of applications. Among the important aspects are:
1. Capacity for Switching
Toggle switches have varying switching capabilities, which govern how much current may flow through the switch. Switching capacities range from a few milliamps to several amps, depending on the application.
2. Actuator Type
Toggle switches come with different actuator types, which determine the method used to operate the switch. Some of the common actuator types include lever, rocker, and paddle.
3. Contact Configuration
Toggle switches come with different contact configurations, which determine the number of poles and throws in the switch. Contact configurations range from single pole/single throw (SPST) to double pole/double throw (DPDT).
4. Mounting Style
Toggle switches come with different mounting styles, which determine how the switch is attached to a panel or chassis. Some of the common mounting styles include screw mount, snap-in mount, and PCB mount.
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 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:
The most famous type of these toggle switches is 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 flow 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 govern two diverse circuits.
How Does A 2-Way T-Switch Work?
A toggle switch is a type of switch that is operated by a lever or other moving part. The most common type of toggle switch is the:
- 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.
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.
They can be single poles or double poles and can be organized for either momentary or sustained procedures.
Most switches have an illuminated tip that glows when the button is in the ON position, making them easy to locate in the dark.
What are the Components and The Basic Types of Toggle Switches?
Switch types depend on the linking of the electrical circuit that regulates the flow of electricity. In this article, we describe the main components that are essential for creating a functional and efficient electrical circuit. We also elaborate on the type of switch connection required.
There are three main components of a switch:
- Poles: Poles are the central part of an electrical circuit that controls the number of circuits with the help of a switch.
- Single Throw: A single-throw switch consists of one or two pairs of connections that can be either closed or opened.
- Double Throw: A double-throw switch consists of two or more pairs of connections. When the switch is in the “ON” position, current flows through both terminals. However, when the switch is in the “OFF” position, current cannot flow through either terminal.
In this article, we discussed the main types and configurations of switches. Switches can be classified by their specifications and quality of connectivity. The following types are crucial for an electrical circuit:
- SPST (Single Pole Single Throw)
- SPDT (Single Pole Double Throw)
- DPST (Double Pole Single Throw)
- DPDT (Double Pole Double Throw)

1. 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.
When the switch is turned “ON” or closed, current flows through the entire circuit, and the light bulb turns on. However, when the switch is turned “OFF” or opened, the flow of current stops, and the light bulb turns off.
2. 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 is basically tangled in three- a way circuit. For turning the ON/OFF light in the whole circuit from top to end of a flight of steps. Here we explained the 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 be ‘’OFF.’’
- If you did it with switch B and did the whole procedure again, then Light B blinks, and light A will be ‘’OFF.’’
- With this, we can control the whole circuit with one source
3. DPST (double pole, single throw)
DPST or Double Pole, Single Throw is an electrical switch that controls two separate electrical circuits or devices. It has two poles or circuits, each with a single input and output connection, and only one of the two possible output connections can be active at a time.
This switch is commonly used to turn on and off multiple devices at the same time, such as a light and a fan. Activating the switch toggles the position of the internal contacts, allowing for the connection of one circuit while breaking the connection of the other.
DPST switches are easy to use and are available in different shapes and sizes for various applications. However, they do not offer any protection against electrical shock or overload. That’s why the installation should always be performed by a qualified electrician to ensure safety and proper functioning.
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.
By using the position of a switch, we can easily route each contact and identify the connection paths.
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.
Toggle Switch Accessories

Rocker Switch Vs Toggle
There are two main types of toggle maintenance.
- Toggle switch
The main difference between toggle switches and rocker switches is their mechanism of operation. A toggle switch has a lever that moves up and down to open and close the circuit, while a rocker switch has a rectangular button that rocks back and forth to turn it on and off.
Toggle switches are more commonly used in industrial applications, as they offer better durability and resistance to damage. They are often found in heavy machinery, electronic devices, and automotive applications.
Rocker switches, on the other hand, are more common in household and commercial settings, such as in lamps, computers, and other appliances. They offer a sleeker and more modern look and are easier to operate with a simple push or press of a button.
|Toggle switch||Rocker 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.
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, and some desire the handsome appearance of a rocker switch.
But on the contrary, side, if the products are selected for the marine industry, we suggest the toggle switch for better results and security.
Do Toggle Switches Need Grounding?
These are collective switch types 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.
In conclusion, a toggle switch is a manually operated switch that is controlled by a projecting lever, handle, or thumb. It is often used to regulate a circuit by interrupting the flow of current. Toggle switches are available in many different styles and sizes and can be used for a variety of applications.
