Rockers Switches

Lever or rocker switches are among the most popular type of industrial or commercial switch. In terms of structure, they resemble toggle switches. Using a rocking action, the switch can turn one or more devices on or off, serve as a conductor or control circuit, or even interrupt current flow. Due to their reliable and practical design, rocker switches are widely used in a variety of applications.

Application Field

Rocker switches are commonly used in many industries, including aerospace, manufacturing, instrumentation, robotics, and marine applications. They can also be used in appliances, lighting systems, pumps, outdoor/indoor temperature control, and many other applications. Not only are they multi-functional, some rocker switch models feature multiple LED indicators, displays, and even a selection of custom graphics.

Rocker switches are more popular than ever, due to their ability to withstand the rigors of regular usage. Many current switches have IP67 ratings which make them dustproof and waterproof, making them ideal for both indoor and outdoor settings. High impact models are also available, designed for use in applications such as traffic control, emergency/warning systems, and public safety. This type of switch comes with sealed casing, ensuring a safe and secure experience.

Principle of Work

Rocker switches, like other types of switch controls, utilize several sources of power. They relay commands from a specific device to a unit that carries out the desired operation. Depending on the design of the switch, the source of power can range from electricity or a mechanical source. When it comes to electrical applications, rocker switches typically employ two methods of power transmission: direct current (DC) or alternating current (AC).

Once the switch receives a power supply, the rocker mechanism triggers the switch, causing the contact points to make or break the connection. The internal structure of the switch is typically composed of a headpiece and several components that form the electrical contacts. These components, such as bridges and ramps, direct the flow of current by “pushing” or “pulling” the appropriate contacts with the headpiece. In layman’s terms, this process creates either an open circuit or a closed circuit, depending on the position of the switch.

Conclusion

Rocker switches are a popular and versatile type of switch control, used for a wide variety of applications. Not only are they reliable and easy to use, but their multiple safety features make them an even more attractive choice for industrial settings. Thanks to its durability and reliable operation, rocker switches are here to stay.
