Introduction to Rotary SwitchesRotary switches are devices used for making or breaking an electrical circuit by using a rotating tool. They are usually used to control a variety of components from simple electrical switches to complex electronic systems. A rotary switch is composed of a circular frame, with multiple contacts on its circumference, and an actuator that can rotate relative to the frame. The contacts are arranged in a number of ways, each tailored to its specific application. Most rotary switches have a variety of features that make them unique. The most common features are the number of poles, the number of throws, the contact material and the actuation type. All of these features help determine the application fields and working principles of the switch.71ASF30-01-1-09N Application Field and Working PrincipleThe 71ASF30-01-1-09N rotary switch belongs to the ASF series from NKK Switches. It is a 3-pole, 9-position switch with a snap-in actuator. The contact material is silver-plated copper alloy with a maximum current rating of 1A. It has a broad application and is suitable for use in computer peripherals, control systems, LCD display systems, power distribution circuits and other high-frequency digital circuits.When the switch is in its normal, or “off” position, the spring loaded contacts remain open. When the actuator is rotated, the spring loaded contacts are pushed inwards, creating an electrical connection. Once the actuator is returned to its normal position, the contacts are released and the connection is interrupted. The 71ASF30-01-1-09N is a versatile switch that can be used in a variety of applications. It is ideal for use in applications where high frequency, low current, and a wide range of positions are needed. It is also immune to shock, vibration and mechanical abrasion, making it suitable for use in harsh environment applications. In conclusion, the 71ASF30-01-1-09N is a reliable and versatile rotary switch with a broad range of applications. Its contact material and maximum current rating make it ideal for a variety of control systems and digital circuits. Thanks to its snap-in actuator, it is capable of handling high frequency operation and can withstand shock, vibration and mechanical abrasion.
