Rotary Switches

Rotary switches are switches with several positions available that can be usedin many different ways. Rotary switches provide an economical and versatile solution to switch many different inputs or outputs. When a rotary switch is used, it has a rotating shaft that can be manipulated in order to select one of the different positions. These types of switches are commonly used in applications like switching power sources, controlling multiple outputs, and providing precise control over a wide range of applications.The 51KST30-01-2-03N is a type of rotary switch that is specifically designed for applications where precise and reliable control is a priority. This switch features a multifunction design that allows for 2, 3, or 4 pole switching in the same form factor. Additionally, it features a wide range of available positions, ranging from 30 to 20 and even up to 5.In terms of its application field, the 51KST30-01-2-03N is most commonly used in industrial applications. It is particularly popular among engineers and technicians who need to control and switch between multiple sources. In industrial applications, there is typically high precision required, and this type of rotary switch provides the accuracy and dependability necessary. The switch’s various positions also make it well-suited for applications that require different outputs or sources to be switched.

Working Principle

The working principle of a rotary switch is relatively straightforward. When the switch is in its “OFF” position, no current is passed through the circuit.When the switch is placed in one of its different positions, an alternate current path is established and a different output is activated. In the case of the 51KST30-01-2-03N, the switch can provide up to 2, 3, or 4 pole switching depending on the application.The shaft of the rotary switch is the main point of contact between the user and the switch. The shaft is operated by rotating it and can be locked in one of the predetermined positions. There is also a contact block which contains multiple contacts that close when the switch is in the desired position. Depending on the type of rotary switch and the number of positions, the contact block will contain the corresponding number of contacts.In operation, the user rotates the shaft in order to select the desired position and the contact block completes the circuit, allowing the current to pass through. This completes the current path and provides the desired output.

Conclusion

Rotary switches are a versatile and cost-effective solution for many different applications. The 51KST30-01-2-03N is a type of rotary switch that is specially designed for industrial applications, offering precise and reliable control. The working principle of a rotary switch is based on the shaft being rotated and the contact block completing the circuit in order to activate the desired output. This type of switch is ideal for situations where multiple sources or outputs must be selected.
