Rotary switches are electronic devices used to change the route of a given electric current. They come in a variety of shapes and sizes, and their main purpose is to divert electrical connections. One typical example of a rotary switch is the 51EM30-01-2-03N, a three phase rotary switch.

Overview

The 51EM30-01-2-03N is a single-pole, multi-position rotary switch with three poles. It requires a low voltage and current, and has an insulation voltage of 500 VAC. The switch uses two shorting links, and its terminals are stainless steel. This type of device does not allow for adjustment when changing its position.

Application Field

The 51EM30-01-2-03N is best used in applications where the switching of electrical connections is necessary. Some common uses include switching in electrical motors, controlling household appliances and machinery, and controlling small electronic devices. It is also used in industrial process control systems as a part of a larger system. This switch is ideal for applications that require a low voltage, a steady current, and a high-voltage insulation. It is also suitable for applications with a need for quick and reliable switching.

Working Principle

The 51EM30-01-2-03N switch uses two shorting links to divert electrical current by applying a stem and two shorting links. When the stem is turned, the two shorting links come in contact with two adjacent electrical points, closing the gap between them, and re-routing the flow of electricity. This is known as ‘polarity reversal’, and is the basis for the 51EM30-01-2-03N’s working principle.

Safety Features

The 51EM30-01-2-03N switch is designed with safety in mind. It has an insulation voltage of 500 VAC, which ensures that it will not be affected by minor electrical surges. This feature also ensures that the switch will not cause an electrical-shock if touched unexpectedly. Additionally, the switch is made of stainless steel, which ensures that it won\'t corrode over time.

Conclusion

The 51EM30-01-2-03N is a single-pole, multi-position rotary switch with three poles. It is commonly used for switching in electrical motors and industrial process control systems, controlling household appliances and machinery, and controlling small electronic devices. It requires a low voltage and current, and has an insulation voltage of 500 VAC. The switch is also designed with safety in mind with its stainless steel body and high-voltage insulation. The switch uses two shorting links and its principle is based on polarity reversal, making it one of the most reliable and convenient rotary switches available.
