What is a Toggle Switch?

These switches are activated by a lever – moved back and forth, resembling a “toggle.” They have two positions that are “on” and “off.” Other names for toggle switches are joystick switches featuring a rocking mechanism. 

Applications are versatile as these switches are in electronic devices and systems due to their simplicity, durability, and ease of use. The best part? You can easily find toggle switches in a variety of styles and sizes.

How Does a Toggle Switch Work? 

All done with what is a toggle switch? Let’s now look at the working of a toggle switch!

The working of a toggle switch is pretty simple! There’s a lever on the external side and two contacts inside the switch. The “off” position means the inside contacts are open, preventing the flow of electric current through the switch. 

However, the lever is moved to the “on ” position, and the contacts close. This allows the current to pass through and complete the circuit. These switches find applications where a manual, physical action is needed to control the circuit. 

Types of Toggle Switches 

There are many types of toggle switches available. You’ll find options that are different in size and style. Let’s look at some!

Based on Functionality

Now that you know about what is a toggle switch, its types based on functionality are:

Light-emitting diode toggle switches feature LEDs in the switch design. The lever is illuminated, clearly indicating the switch’s status. 

This LED feature adds a unique character to the switch functionality, enhancing visibility in low-light conditions. LED switches are suitable in applications where visual feedback on the switch state is essential, like automotive panels or control interfaces.

A toggle switch with a cover provides an added layer of protection to the switch mechanism. The cover is made of durable materials and shields the toggle from environmental factors. Hence it prevents dust, moisture, or accidental interference. 

This enhances the reliability and longevity of the toggle switch. Toggle switches with covers are crucial for applications in outdoor environments, industrial settings, chassis, off-road lights, etc.

Based on Contact Configurations 

Toggle switches also have types based on the number of poles and throws. Poles indicate how many separate circuits a switch can control simultaneously. The throw of a switch refers to the number of positions or states a switch can adopt. 

Types of toggle switches as per connections are:

SPST toggle switches have two terminals. There’s one pole, meaning they control one circuit and a single throw, indicating a single on/off position. 

Single Pole Single Throw (SPST) Toggle Switches

A single pole controls one circuit in SPDT toggle switches. But there’s a double throw, thus allowing the switch to be in one of two positions. This switch is best in scenarios where a device needs to alternate between two separate circuits.

Single Pole Double Throw (SPDT) Toggle Switches

DPST toggle switches possess two poles. This allows them to control two independent circuits simultaneously. However, they only have a single throw – they can switch both circuits on or off simultaneously.

Double Pole Single Throw (DPST) Toggle Switches

DPDT toggle switches are more versatile. They have two poles and two throws. The double pole allows them to control two circuits independently. On the other hand, double throw allows choosing between two different positions for each circuit.

Double Pole Double Throw (DPDT) Toggle Switches
