Rotary switches are mechanical switching components that require manual operation of a user-operated control. They are used in a variety of industrial settings, and are designed to work in a range of temperature and pressure regimes. The 71MBS30-03B05N is a rotary switch that is commonly used in applications where simplistic functioning, robustness, and reliability are of utmost priority.

Application Field

The 71MBS30-03B05N is a compact one- or two-pole (single, double or triple-throw) rotary switch. It is a medium-size switch that has a durable and resilient solution for fast mode changes and/or application changes, making it ideal for a wide range of applications. These include but are not limited to automotive, machine tool, conveyor, marine, military, and process control applications.

Design and Construction

The 71MBS30-03B05N is constructed from thermoplastic, which offers superior strength and durability in most applications. It has a wiper-contact mechanism, which allows for smooth switching between poles without any loss of power. The pole-switching mechanism uses a screw-type latching arrangement with a removable screw terminator for easy wiring. The switch has an integrated push-button, allowing for switching between poles without having to access the rotary switch console.

Selection Guide

When selecting the right rotary switch for a given application, users need to consider a variety of properties, such as operating voltage, temperature range and pole positions. The switch should be robust and reliable, with a suitable rating to handle the specific application’s requirements. The 71MBS30-03B05N is rated up to 10A and 250VAC and is rated to IP54, meaning it is suitable for use in most applications.

Working Principle

The 71MBS30-03B05N operates on the principle of a rotary switch. As the control head is turned, a mechanism inside the switch connects the internal wiring that links the poles together. The rotary switch has a number of contacts arranged like the spokes of a wheel. When the rotary switch is turned, the contacts move over one of the available poles. This action closes a circuit, enabling power to flow through the switch. This operation can be used to control electrical circuits, lights, motors and other appliances.

Conclusion

The 71MBS30-03B05N is highly reliable and precisely engineered, making it a great choice for applications in a variety of industries. Thanks to its robust construction, rating, and pole-switching mechanism, the 71MBS30-03B05N allows for fast mode changes and is ideal for most industrial settings.
