Rocker switches come in a variety of different styles to suit many applications, including the LRA211-RS-B/125N series. It is designed for use with lighting, motor, heater and many other areas. To better understand its application field and working principle it is first necessary to explain its construction and design.

Construction

The LRA211-RS-B/125N series is a single pole double throw device that can control a two-position load. It is a two-part design, with a base and a Rocker, connected via a stick called an actuator. The bottom part is then mounted onto a panel or board via screws or bolts through the bottom side. The top part is the rocker, and is made of an insulating material such as plastic or nylon. It contains a light spring which helps to keep the rocker in the off or neutral position.

Design

The design of the LRA211-RS-B/125N series is quite basic. It features two on/off buttons for switching power. The terminals are numbered 1-4 and are arranged in a rectangular shape. The 1-4 contacts that the terminals connect to are usually for the two positions of the switched load, 1-2 for the on position, and 3-4 for the off position. It is marked with the IEC standard 60669-1.

Application Field

Given its versatility and reliability, the LRA211-RS-B/125N series offers itself as a great choice for various applications. It can be used to control lighting, motors, heaters, and many others. Its compact design and easy installation make it popular in many commercial and industrial settings. It is also very cost-effective, making it a great choice for projects with tight budget constraints.

Working Principle

The LRA211-RS-B/125N series works on the basis of a pull action. When the button is pushed, it causes the actuator to move up, which in turn causes the contacts on the terminals to move up or down. When the button is pushed one way, the contacts on the terminals will make contact with one of the positions, thus turning the load on. When the button is pushed the opposite way, it releases the spring, which causes the contacts to move to the off position, thus turning the load off.

Conclusion

The LRA211-RS-B/125N series rocker switch is an ideal solution for applications which require two position control. It has a durable quality, being able to withstand up to 5.000 cycles, and its design and size make it perfect for both commercial and industrial settings. Its cost-effective nature also makes it a great choice for tighter budget applications. Its proper understanding and application field can lead to successful results.
