Rocker switches are very versatile in their application field and are used in a range of industrial, commercial and residential applications. In this article, we will look at the working principle of a typical rocker switch and the types of application in which it is employed.

A rocker switch is a type of toggle switch that is actuated by the user pushing a plunger or rocker arm in one direction or the other. The switch makes contact with both sides of the electrical circuit and can be used to control the flow of electricity through a variety of different devices. In general, there are two types of rocker switches: single pole (SPST) and double pole (DPST). The SPST type has a single circuit that is closed when the plunger is pressed one way, while the DPST type has two circuits—one on each side of the switch—that are both opened or closed simultaneously when the plunger is pushed one way or the other.

The working principle of a rocker switch relies on a set of contact points that are forced to come together when the rocker arm is depressed. The contact points are made from materials such as metal, plastic or nylon, and can be either single or double. These contact points then complete the electrical circuit and allow the device to be turned on or off.

Rocker switches can be used in a wide range of industrial and commercial applications, including lighting and the control of ventilation systems. For example, they are commonly used in computer or office equipment such as fax machines, printers and photocopiers. In addition, they can also be used in domestic electrical appliances, such as lamps, television sets and vacuum cleaners.

Rockers switches are also increasingly being used in more advanced control systems. For instance, in industrial automation systems, rocker switches may be used to control the on/off states of motors, solenoids, heating elements and lighting systems. The same type of switch is also used in aircraft to control the devices in the cockpit, including the landing gear and the flaps.

The benefit of rocker switches is that they are relatively easy to install, maintain and operate. Additionally, their toggle action makes them well-suited for quickly switching between different system functions. As a result, they have become a popular choice for professional applications as well as home use.
