Rotary Switches: 083171-2-03N Application Field and Working Principle

A rotary switch is an electrical on/off switch which is operated with a rotary motion, typically using multiple contact points. This type of switch is commonly employed in a variety of applications such as industrial control, audio equipment, sensors, home appliances and phone systems. In this article, the application field and working principle of a particular rotary switch, Model 083171-2-03N, will be discussed.

Application

The 083171-2-03N model is a normally open type of rotary switch, different from the usual normally closed type of rotary switch. It has a two-pole, two-throw configuration and is designed for applications requiring the routing of two independent sources of electricity to two independent loads. Thus, it is suitable for multi-circuit control, such as selecting the source of light for a display sign, for instance. It is also applicable for the switching of one circuit between two loads, such as the direction control a motor.

This model also features an anti-shock resistance, making it suitable for environments with a high degree of vibration. Additionally, its insulation material is highly temperature resistant and is capable of being used in operating temperature ranges of -20 to 105 degrees Celsius. This 083171-2-03N model is compact and requires only a minimal panel space — making it suitable for when space constraints are an issue.

Working Principle

The 083171-2-03N model is composed of a stationary contact element, a rotational contact element, an end-stop and an actuating element. The actuating element is the knob; when turned, it causes the rotational contact element to turn along with it. As it turns, the contacts of the rotational contact element come in contact with those of the stationary contact element.

The 083171-2-03N model is designed such that when the knob is turned in its minimum position, the contacts are open, meaning that no electricity is able to flow through them. However, when the knob is turned into its maximum position, the contacts are closed, thus allowing the electricity to flow through. The end-stop acts as a mechanical provision to limit the rotation of the actuating element, so that it does not rotate past its maximum position.

The 083171-2-03N model also comes with silver alloyed contacts for improved conductivity, as well as insulation that is resistant to water and oil, making it suitable for applications that require some degree of protection from moisture and foreign contaminants.

Conclusion

The 083171-2-03N model of rotary switches is a normally open type of switch suitable for a wide array of applications, from route control to direction control of a motor. It features a two-pole, two-throw design and comes with silver alloyed contacts for improved conductivity, as well as insulation that is resistant to water and oil. Additionally, its compact design allows it to be used in tight spaces, making it ideal for applications with space constraints.
