Rotary switches are a type of electrical switches found in many areas, including industrial and electronic applications, as well as domestic applications. The rotary switch is generally used to provide a manual override of an electrical circuit, allowing the user to switch the circuit on or off. In industrial and electronic applications, they are often used to open or close electrical contacts and regulate the flow of current from one device to another. They are typically used to change the setting of electrical circuits or to select between different channels in a multi-channel system.

The 09A30-03-2-03N rotary switch is a two-pole, three-circuit rotary switch. It is constructed from a base and a cam that both rotate around an axis. The base is an insulator, while the cam has multiple contact points that can be moved by rotating the cam in relation to the base. As the cam is rotated, it comes into contact with the contact points on the base and changes the electrical circuit depending on the cam\'s position. When all the switches are in the same position, the circuit is open. When the cam is rotated to different positions, the contact points on the base, will then connect and close the circuit.

The 09A30-03-2-03N rotary switch is commonly used in applications such as medical devices and industrial equipment. Such as a medical device, it can be used as a selector switch to adjust the intensity of a medical device, like a pulse oximeter. In industrial equipment, it can be used in machines that require multiple adjustments to be made to their operation, such as in combination switches. It can also be used to control the flow of current from one device to another, such as in industrial temperature controllers.

The working principle of a rotary switch is quite simple. It relies on the contact points between the rotary switch\'s cam and base to close or open the electrical circuit. As the cam is rotated, the contact points will either come into contact with each other or break the contact with each other, depending on how the cam is rotated. When the contact points are in contact with one another, a closed circuit is formed, which allows an electrical current to flow through. When the contact points are not in contact with each other, the circuit is open and the electric current is not allowed to flow.

In summary, the 09A30-03-2-03N rotary switch is a two-pole, three-circuit switch. It is typically used in industrial and electronic applications to open or close electrical contacts and regulate the current in the circuit. It is built with a base and cam that rotate around an axis, and the contact points on the cam are used to open or close the electrical circuit depending on the position of the cam. This is a basic, yet highly effective switch that is used in a variety of applications.
