LED switches are used in a variety of applications where visual indication is required. These switches are designed to provide a bright and easy to see indication of the switch status. The 4 Pin LED Switch is one of the most commonly used LED switches that is available in the market. This switch is widely used in a number of applications, including automotive, marine, and industrial applications. In this article, we will discuss the wiring diagram of the 4 Pin LED Switch and how to use it in different applications.
What is a 4 Pin LED Switch?
The 4 Pin LED switch is a type of switch that has an integrated LED light. The LED light is used to indicate the switch status. When the switch is turned on, the LED light illuminates, and when the switch is turned off, the LED light turns off. The switch has four pins that are used for the power supply and the control of the LED light. The pins are commonly labeled as positive, negative, output, and input.
Pin Definitions
The following table provides the pin definitions of the 4 pin LED switch:
| Pin | Name | Description |
|---|---|---|
| 1 | Positive | The pin that is used to supply power to the switch. |
| 2 | Negative | The pin that is used as the ground for the switch. |
| 3 | Output | The pin that is used to connect the load or the device that is being controlled by the switch. |
| 4 | Input | The pin that is used to control the switch. |
Wiring Diagram of 4 Pin LED Switch
The following diagram shows the wiring of the 4 Pin LED Switch:
The positive and negative pins of the switch are connected to the power supply. The output pin of the switch is connected to the load or the device that is being controlled. The input pin of the switch is connected to the control circuit, which is used to turn the switch on and off.
Wiring Example
Let’s consider an example where we want to use the 4 Pin LED Switch to control a LED strip. The LED strip requires a 12V DC power supply, and it draws a current of 1A. The following diagram shows the wiring of the LED strip and the 4 Pin LED Switch:
In this example, the positive and negative pins of the switch are connected to the 12V DC power supply. The output pin of the switch is connected to the positive terminal of the LED strip, and the negative terminal of the LED strip is connected to the ground of the power supply. The input pin of the switch is connected to a control circuit, which is used to turn the switch on and off.
FAQ
What is the function of the LED light in the 4 Pin LED Switch?
The LED light in the 4 Pin LED Switch is used to indicate the switch status. When the switch is turned on, the LED light illuminates, and when the switch is turned off, the LED light turns off.
How can I connect the 4 Pin LED Switch to a microcontroller?
You can connect the input pin of the 4 Pin LED Switch to a digital pin of the microcontroller. You can use the microcontroller to turn the switch on and off by setting the digital pin to high or low.
What is the maximum current rating of the 4 Pin LED Switch?
