Rotary switches: uses and characteristics
Rotary switches are essential components in electronics and engineering due to their versatility and precise selectability. M2B is a company specialising in their production and is internationally recognised for the high quality of its switches. With decades of experience in the industry, M2B has a deep understanding of the design and functionality of these devices. This article explains exactly what these rotary elements are, what their main advantages are and when it is advisable to use them.
What are rotary switches?
Rotating switches, also known as rotary switches, are mechanical devices that allow the position of an electrical contact to be changed by rotating a shaft. This action selects different circuits or options in an electrical or electronic system.
Unlike linear or toggle switches, rotary switches are capable of selecting multiple positions with a single rotary action.
They consist of a shaft, a rotor and several contacts that are activated depending on the position of the rotor. The number of available positions can vary. Thus, it provides from two to more than ten different alternatives.
It should be noted that, provided it is a quality product, its robust design and ability to handle high currents make it suitable for complex industrial and electronic applications. Other advantages of the rotary switch include the following:
Versatility. It can be used in a wide variety of devices, from audio equipment to industrial machinery.
Durability. Its solid construction means that it has a long service life. It tolerates thousands of operating cycles without significant degradation.
Accuracy. Integrates an accurate selection of options or functions, which is crucial in applications that demand precise configuration.
Simplicity of use. Its intuitive operation makes it easy to change status without the need for complex interfaces. This makes it suitable for use in both industrial and domestic environments.
Current handling capability. This type of device withstands high currents, making it suitable for applications requiring high power switching.

Why and when to incorporate a rotary switch?
Rotary switches are particularly useful in situations where it is necessary to choose between multiple options with a single action. Their inclusion is suitable for applications such as the following:
- Audio and consumer electronics applications. In audio equipment, rotary switches are used to select operating modes or to adjust specific settings. For example, in amplifiers and receivers they can be used to toggle inputs or to adjust volume levels and equalisation
- Instrumentation and measurement. Measurement and test devices, such as multimeters, often incorporate this type of switch to select measurement ranges or test types. This provides users with a simple way to customise settings, dispensing with complex digital interfaces.
- Industrial automation. In the industrial environment, these elements are indispensable for the control of machinery and automation systems. They enable operators to choose specific operating modes or configurations quickly and efficiently, ensuring reliable and safe control.
- Control panels and switching devices. They use these rotary products for the selection of circuits or operating modes. This facilitates the management of complex systems with multiple options, optimising control and operational safety.
In short, rotary switches offer an efficient and reliable solution for the wide selection of options for different applications. If you are interested in learning more about these high quality products, please contact M2B.
