412-5

Rotary switches are a specific type of switch that is used to control an electrical circuit. They are typically composed of a body, a rotary actuator, and a set of contacts. The body is typically constructed of an insulating material such as plastic or phenolic resin, while the actuator is usually made from metal or plastic. The contacts can be either fixed or moveable, depending on the application.

The 412-5 rotary switch is a popular choice amongst many electronics engineers due to its wide variety of applications and features. The 412-5 features five poles, a single throw actuator, and a total of six positions. This allows for the switch to be used for a range of functions, such as steering or switching circuits, permissive entry systems, and test instrument applications.

In terms of how it functions, the 412-5 rotary switch is quite simple. When the actuator is rotated, it moves the contacts around the cam. This allows the user to select different positions, each of which is associated with a different connection. In some setups, this allows a single switch to control multiple circuits, but it can also be used to open or close a single circuit depending on the application.

This type of switch can be further augmented with various features, such as a locking mechanism or a latching actuator. This allows the switch to hold its position after the user has finished moving it, allowing it to remain in the position that the user has chosen until they manually change it again. This is useful for applications where continuity is required, such as in access control systems.

The 412-5 rotary switch is a versatile and reliable choice for a variety of applications. Its range of features and contact configurations make it suitable for many different types of applications, from access control systems to test instrumentation. Its easy-to-use configuration also make it a popular choice amongst many engineers and hobbyists. With its long history of reliability and performance, the 412-5 rotary switch is sure to continue to be a popular choice in the future.
