Simple Wiring Diagram for 4-Pin Rocker Switch

A 4 Pin Rocker Switch is a type of switch that has four pins and is commonly used to control the flow of electric current. It has two positions, an On/Off position and a Spring Return position, which allows it to be used in a variety of applications. This type of switch is popular in both commercial and residential settings, where it is used to control lights and appliances.

A 4 Pin Rocker Switch works by using two contact points that are connected to a spring-loaded mechanism. When the switch is pressed down, the contact points close and allow current to flow through. When the switch is released, the contact points open and the circuit is broken.

There are three positions of a 4 Pin Rocker Switch, which are: Off, On/Off, and Spring Return. Off is the default position, meaning no current will flow through the switch when it is in this position. When the switch is pressed down, it changes to the On/Off position, allowing current to flow through. When the switch is released, it returns to the Off position. The last position is the Spring Return, which is a momentary position - when the switch is pressed, current will flow until the switch is released.

Wiring a 4 Pin Rocker Switch is relatively simple and straightforward. The four pins are labeled as follows: COM (common), NC (normally closed), NO (normally open), and E (earth). The COM pin is connected to the power supply and is the most important pin. The NC and NO pins are connected to the device that needs to be controlled. Finally, the E pin is connected to a ground or earth wire. Depending on the application, these wires will either be connected directly to the power supply or to an internal relay.

When wiring a 4 Pin Rocker Switch for a simple circuit, the NC and NO pins are wired to the device and the COM pin is wired to the power supply. When the switch is pressed, the circuit is completed and the device is powered. For example, a 4 Pin Rocker Switch can be used to control a light bulb. When the switch is pressed, the light bulb will turn on and when released, the light bulb will turn off.

Likewise, a 4 Pin Rocker Switch can also be used to control a light bar. In this case, the NC and NO pins need to be connected to the light bar’s input and output terminals, and the COM pin needs to be connected to the power supply. When the switch is pressed, the light bar will turn on and when released, the light bar will turn off.

The purpose of a 4 Pin Rocker Switch is to provide an easy way to control the flow of electric current. It is a convenient, reliable, and cost effective solution for many applications, such as lighting and appliance control. Additionally, a 4 Pin Rocker Switch is also commonly used in automotive, marine, and industrial applications.

Common applications of a 4 Pin Rocker Switch include car audio systems, alarm systems, and home theater systems. Additionally, they may also be used to control automated devices such as motors, pumps, fans, and valves. There are also special applications where the switch is used to control multiple devices at once, such as in lighting circuits.

A 4 Pin Rocker Switch can handle high current, depending on its rating. Generally speaking, 4 Pin Rocker Switches can handle anywhere from 10 amps to 30 amps. However, it is important to check the switch’s rating before connecting it to a high powered device or circuit.

Finally, 4 Pin Rocker Switches come in a variety of colors, including black, white, red, and green. This allows for customization and adds an aesthetically pleasing touch to any application. Additionally, some switches may also feature illuminated buttons, which make them easier to locate in the dark.

In conclusion, a 4 Pin Rocker Switch is a versatile and reliable switch that can be used in a variety of applications. It has two positions, On/Off and Spring Return, and features four pins that are labeled as COM, NC, NO, and E. When wiring a 4 Pin Rocker Switch, the NC and NO pins are connected to the device while the COM pin is connected to the power supply. 4 Pin Rocker Switches are capable of handling high current and come in a variety of colors. They are commonly used in car audio systems, alarm systems, lighting circuits, and other automated devices.
