Rocker switches are simple mechanisms used to connect and disconnect an electrical circuit. The WR127J71V3Q2 is a single pole, two-way rocker switch commonly used for applications such as lighting, and alarms. Made from high quality plastic and metal parts, the WR127J71V3Q2 provides a robust and durable construction that is dust proof and shock resistant.

Working Principle

The working principle of a rocker switch is based on the simple idea that when two contacts are closed, an electrical circuit is made and when the contacts are open, the circuit is broken. In the case of the WR127J71V3Q2, a lever connected to a curved plate on the bottom of the switch acts as a switch lever. When pressure is applied to the lever, the plate forces the contacts of the switch to open or close, thus either connecting or breaking the circuit.

Application Field

Due to its robust design, the WR127J71V3Q2 is mainly used in industrial and automotive applications. It is perfect for use in electric lighting, machinery, security systems, and other industrial equipment. For in-car applications, it can be used to control dashboard indicators, fog lamps, emergency lights, and much more. It can also be used for home electrical wiring in lighting, lamps and electrical appliances.

Installation

Installation of the WR127J71V3Q2 is relatively simple, although if it is directly installed, it should be double checked for polarity in order to prevent short circuits. The wiring is done by joining a live wire to the rocker switch’s output pin, and the other end is connected to a device that needs to be powered. When the switch is activated, the device is powered, and when it is shut down, the device is disabled.

Conclusion

Rocker switches are easy to use and hard wearing, and the WR127J71V3Q2 makes this type of switch reliable and suitable for a wide range of applications. Its robust design and easy installation make it an ideal choice for many industrial and automotive applications, and it can be used in a range of other settings.
