Rotary Switches

Rotary switches are universally used for connecting and disconnecting a variety of electrical circuits. They are convenient and reliable, and with the use of intermediate connection zones, their switching capacity can be increased. The 51E30-01-1-05N rotary switch is one of the most common and widely used models.

Application Field

The 51E30-01-1-05N rotary switch is widely employed in a variety of applications. It is commonly used in alarm systems, power systems, control systems, and other circuits involving switching. It is also widely used in audio and video systems, data communication systems, and others.

This switch is highly reliable and suitable for a wide range of voltage and current. It is designed with a variety of poles and contact arrangements, and can be used with a multiple of different circuits, both AC and DC. It is also suitable for use for appliance switching.

Working Principle

A rotary switch operates by mechanical action, as opposed to the electrical action of a toggle switch. A cam inside the rotary switch interacts with the contact wipers to either make or break the circuit connection. When the switch is in the OFF position, the contact wipers are sealed off, and when placed in the ON position, the contact wipers connect, completing the circuit. This creates a reliable and safe connection, and eliminates the possibility of static electricity.

The 51E30-01-1-05N rotary switch also has a special set of pins that act as a latching mechanism. When the switch is moved to another position, these pins move in a way that locks the switch into that position, keeping it secure and in place until it is reset to another one.

In addition, this rotary switch is designed with a fail-safe feature, which means that if the switch is in the OFF position, the circuit will remain open even if power is applied. Similarly, if the switch is in the ON position, the current will remain on even if the power is cut off.

Summary

The 51E30-01-1-05N rotary switch is a versatile and reliable switch suitable for a wide range of applications. It is easy to operate, with a simple mechanical action. Its latching mechanism ensures that the switch remains in the desired position regardless of power supply, and its fail-safe feature ensures that the circuit connections remain either closed or open even if power is applied or cut off.
