Rotary switches are devices that allow electrical connections to be established between circuits or devices through rotation. Typically, rotary switches have multiple contacts at different angles, which correspond to the state of the switch. One of the most popular types of rotary switches is the R20405RN02Q, which is used in a variety of applications. This article will discuss the application field and working principle of the R20405RN02Q.

Application Field of R20405RN02Q

The R20405RN02Q is a single deck rotary switch that is commonly used in telecommunications, household appliances, audio equipment, and automotive electronics. The device is designed for indoor applications, and is equipped with a metal plate mount and a threaded hole. The contacts of this rotary switch are fitted with gold-plated silver contacts, which provide superior electrical conductivity and durability. The device is also UL and CSA approved, and has an IP 60 degree protection rating.

The R20405RN02Q is one of the most popular types of rotary switches due to its reliable performance and versatile design. The switch is capable of handling up to 2 AMPs and has a maximum voltage rating of 250 VAC. It is also electrostatically shielded, which improves its noise suppression capabilities. This makes it ideal for use in a variety of applications, such as in switching devices and current-limiting applications.

Working Principle of R20405RN02Q

The R20405RN02Q is a single deck rotary switch, which means that it has only one shaft with several contacts on it. These contacts are arranged in a circle around the shaft, and when the shaft is rotated, the contacts are connected to different parts of the circuit. The electrical contact is made when a conductive contact point from the switch is connected with the intended contact point in an electrical circuit, thereby making an electrical connection.

The R20405RN02Q switch utilizes a latching contact system, which helps ensure a secure and reliable connection. The switch requires a drive torque of only 3 N-cm to change its position, meaning it can be easily operated by hand. The switch also has a contact bounce time of 3 ms, which ensures that the contacts are secure, and eliminates the possibility of unreliable connections.

Conclusion

The R20405RN02Q is a popular single deck rotary switch that is used in a variety of applications, such as telecommunications, household appliances, audio equipment and automotive electronics. The device is equipped with gold-plated silver contacts, which provide superior electrical conductivity and durability. Additionally, the switch utilizes a latching contact system and requires a drive torque of only 3 N-cm for operation. These features make the R20405RN02Q an ideal choice for switching circuits and current-limiting applications.
