Introduction

Rotary switches are commonly used in electronic and electrical applications due to their reliability, economy, and ease of use. One such type of rotary switch is the 71BF36-04B10S. This type of rotary switch offers improved performance and more flexible capabilities than conventional rotary switches. In this article, we discuss the application field and working principle of 71BF36-04B10S rotary switches.

Application Field

The 71BF36-04B10S rotary switch is mainly used in industrial, medical, and aerospace applications. It is designed to be used in applications that require precise switching, such as circuit breakers, power supplies, motor control, and medical instruments. In addition, it is also used in applications that require fast response times, such as cell phone switching and other digital communications. The 71BF36-04B10S is certified to meet UL, CSA, TUV, and EN standards for safety, reliability, and performance. It is also designed to meet EIA RS-485 and MIL-STD-859 requirements for switching speed, noise, and power dissipation. As a result, it is a reliable and long-lasting choice for industrial, medical, and aerospace applications.

Working Principle

The 71BF36-04B10S rotary switch operates using a CAM mechanism. This mechanism consists of two main components, a "CAM" and a "BAR". The CAM is a small disk that contains a series of evenly spaced indentations. The BAR is a flat plate that is comprised of several sections. Each section contains a contact and when the CAM rotates, it places each contact in contact with the BAR, thus allowing electrical current to pass through the switch. The CAM rotates around the BAR which is mounted to a pivot point and is held in place using two "pins". When the switch is in the off position, the CAM rests against the BAR, preventing the current from flowing. However, when the switch is in the "on" position, the CAM rotates around the BAR, causing the contacts to make contact with each other and allowing the current to flow. The 71BF36-04B10S rotary switch is also designed with a unique feature called the "Rolling Effect". This feature allows the switch to change from the off to on position without having to wait for the CAM to rotate around the BAR. Instead, the contacts roll over each other as the switch is rotated, thus allowing for faster switching.

Conclusion

The 71BF36-04B10S rotary switch is a reliable and long-lasting choice for industrial, medical, and aerospace applications. It operates using a CAM mechanism and is designed with a unique rolling effect feature, which allows it to switch faster than conventional rotary switches. Finally, it is certified to meet UL, CSA, TUV, and EN standards for safety, reliability, and performance.
