What is a Toggle Switch?
A toggle switch operates by pushing a lever up and down or left and right to switch an electrical circuit. The toggle is a small wooden rod that replaces buttons as a clothing fastener. Due to the resemblance between the switch lever and the toggle used in clothing, the term “toggle switch” was coined.
What are the Types of Toggle Switch?
There are four types of these switches, each with a different combination of poles and throws, such as SPDT, SPST, DPDT, and DPST. A switch’s poles are typically the individual power supplies, whereas its throws are the different locations the switch can control, such as ON and OFF.
1. SPST Toggle Switch
An SPST is a “Single Pole Single Throw” circuit, which includes two terminals, like input and output. Switches like these work like simple ON/OFF switches. In a single branch circuit, this switch makes or breaks a connection between two conductors.
By opening this switch, the circuit will be disconnected, preventing current from flowing through the load. When the switch is closed, current flows throughout the load.
2. SPDT Toggle Switch
A SPDT toggle switch is one that can make or break a connection between two single conductors. SPDT stands for “Single Pole Double Throw”. There are usually three terminals on these types of switches, which are generally used in pairs.
3. DPST Toggle Switch
The DPST switch is used to make or break the connection between two circuit conductors within one branch circuit. DPST stands for double-pile single throw. In general, these switches include four terminals that can be used to connect or disconnect two pairs of terminals at the same time.
4. DPDT Toggle Switch
A DPDT toggle switch is a toggle switch that makes or breaks the connection between two conductors to two separate circuits. The term DPDT stands for double pole double throw. Three and four of these switches are powered, while the remaining terminals, like 1, 5, 2, and 6, are driven by the remaining terminals. Four-way switches are also known as four-position switches.
5. LED Toggle Switch
A LED is usually mounted on the tip of these toggle switches. In this LED, the switch condition is mainly indicated, such as ON/OFF. In handheld devices, as well as front-panel interfaces, these switches are used.
6. Mini Toggle Switch
Switch with mini toggle available in smaller sizes which are also called snap-action switches or micros switches. Switches with spring-loaded toggles respond to some force applied to them. Through current inflow, the switch’s spring activates & shifts the contacts into place. As well as being used in domestic and industrial equipment, these switches are designed to be used extensively in a wide range of applications.
What is the Structure of a Toggle Switch?
