• Introduction

Rotary switches are a type of switch in which a shaft or wheel is rotated to make a series of electrical contacts at different angles. They have been used in many diverse applications, ranging from industrial automation to home appliance, in order to control the functions of a device. The 51CDP30-01RAJS rotary switch is an example of such a device, and this article will look at its application field and working principle.

• Application Field

The 51CDP30-01RAJS rotary switch is a medium–range rotary switch, which is suitable for use in a variety of medium–voltage applications. It is typically used in machines and equipment with a voltage rating of up to 300V. It is particularly popular in industrial automation and control systems, where its adjustable angle of rotation makes it suitable for controlling a range of different functions.

• Design

The 51CDP30-01RAJS rotary switch is a two–pole, two–position switch, with distinct ‘on’ and ‘off’ positions. The switch consists of a rotatable shaft with a pair of contacts located at the end. The rotatable shaft is fitted with four magnified markers, indicating the different positions of the switch. The structure of the switch is designed for improved performance and reliability. The body of the switch is made from specially–treated aluminum, making it highly resistant to corrosion and other environmental factors. The switch terminals are gold–coated to ensure a low–resistance connection, and the rotary shaft is fitted with a highly–durable thrust bearing.

• Working Principle

When the rotary switch is in the ‘off’ position, a pair of contacts are held in place by a spring, preventing a circuit from being formed. When the switch is turned to the ‘on’ position, the contacts are forced open, allowing a current to pass between them. This activates the device that the switch is connected to, and the rotary switch is returned to its original position when the current is switched off.

• Safety Features

The 51CDP30-01RAJS rotary switch is equipped with a number of features to ensure safe operation. The casing of the switch is shockproof, to protect against electrical shock, and all exposed current paths are insulated against contact with live parts. The switch also features an indicative button, which allows users to check that the switch is in the ‘off’ position before it is energized.

• Conclusion

The 51CDP30-01RAJS rotary switch is a reliable and durable switch, designed for use in a variety of medium–voltage applications. It is a two–pole, two–position switch, which can be turned to two distinct positions to activate the device that it is connected to. Its robust design and safety features make it suitable for use in a range of industrial control systems and other devices.
