Rotary Switches

Rotary switches, also known as rotary cam switches or selector switches, are commonly used to select, reverse and reverse motors, conveyor belts and other continuous devices, or to sign a machine out of operation or into a maintenance or repair mode. One of the most common and versatile rotary switches is the 51MBP30-01E02N. This model is suitable for a broad range of applications and is used primarily for motor control.

Application Field

The 51MBP30-01E02N rotary switch is designed for use in commercial, industrial and other harsh environment applications. It is suitable for manual operation and is commonly used for selecting, reversing and controlling motor speed drives in motor control systems. This rotary switch also can be used as a selector switch to set machines into off or operation mode and to choose between single or three-phase reversible motor operation.

Working Principle

Rotary switches work using a rotary cam and contact. When the rotary switch handle is rotated, the cam carries a series of contacts across the rotating switch. The contacting forces are provided by tension springs in the switch, which ensure that the contacts are firmly pressed onto the switch between the two inner plates. This contact switching is employed in the 51MBP30-01E02N rotary switch to establish a connection between the two inner plates and control the current. A locking mechanism is provided on the external head to ensure that the switch cannot be rotated out of the required position once it has been set.

The 51MBP30-01E02N rotary switch uses a reliable mechanical design to provide positive switching with good contact force. Its heavy-duty construction ensures that it can operate in harsh environments and its robust design offers long-term performance and extended product life. Additionally, this switch features a clever optical feedback system, which indicates both current power speed and direction from up to three points in the control circuit.

Conclusion

The 51MBP30-01E02N rotary switch is a versatile and reliable device for controlling motor speed drives and other applications requiring manual operation. Its robust design and clever optical feedback system ensures repeatable and reliable operation, and its heavy-duty construction ensures long-term performance and extended product life.
