Introduction

Rotary switches are poles that, when turned, are used to select different electrical circuits. They are commonly used in a variety of applications such as aviation, aerospace, automotive, industrial and consumer electronic devices. In this article, we will look at the 51A22-01-1-16N-F application field and working principle, specifically for rotary switches.

51A22-01-1-16N-F Application Field

The 51A22-01-1-16N-F is a 16-pole rotary switch designed for heavy-duty, heavily-loaded contact applications such as avionics, military, and automotive applications. It is a multi-pole, multi-position rotary switch that offers electrical protection up to 600V, and comes with a long life of up to 2 million operations. The switch is also highly resistant to shock, vibration and temperature extremes, thus providing reliable operation in even the harshest applications.

51A22-01-1-16N-F Working Principle

The rotary switch works by connecting several electrical control circuits when one of the switches is engaged. The switch is mounted in a housing that is either a single unit with a non-conducting coil spring inside, or a multiple switch unit with individual coils contained in a cylindrical form. The switch is then connected in an electrical circuit with the input contacts on the switch facing the desired output. When the switch is turned, it activates or deactivates the position-to-position control plate by creating a connection or disconnection of the input contacts. This connection or disconnection then sends an electrical signal to the output contacts. The input contacts of the switch are usually made of a high-temperature alloy material such as silver alloy. The output contacts are usually made of brass. The contact pieces can also be made of other materials depending on the application. In addition to the electrical contact, the switch must also contain a mechanism for maintaining its rotational position when the switch is turned. This could be achieved through the use of a cam, a worm gear, or a spring-loaded device.

Conclusion

The 51A22-01-1-16N-F is a heavy-duty, heavily-loaded contact rotary switch suitable for use in a number of applications, including avionics, military, and automotive applications. It is a multi-pole, multi-position switch with a long life, and it offers electrical protection up to 600V. The switch functions by the connection or disconnection of the input contacts, which will then send an electrical signal to the output contacts. A mechanism must also be in place for maintaining the rotational position of the switch when it is turned.
