Rotary switches are a type of electromechanical actuator designed for the purpose of selecting each different electrical functions with the same actuator and reliably breaking the circuit between them. Rotary switches come in various styles, offers different features and serves numerous applications across multiple industries, such as; building automation, telecommunications, audio visual, and many more.

The 71AS30-01-2-04S rotary switch is a latching type switch designed for a wide range of industrial applications. It consists of a stationary contact package with a moveable contact that rotates and clicks into place at each position, which can then be released by pushing the actuator. This is especially helpful for maintaining position if the switch is subject to vibration, or if a process needs to remain in the same position when electricity is cut-off.

The main application field of the 71AS30-01-2-04S switches is the industrial control sector, where it’s commonly used in the control panels of machines, such as cranes and elevators. Additionally, 71AS30-01-2-04S rotary switches are commonly used in touchless operations, like medical facilities, and can be employed to actuate divergent circuit operations, such as reversing motors, relays, and lighting circuits.

The working principle of rotary switches is relatively straightforward ands follows the course of connecting an actuator arm with one or more electrical contacts. When the arm is turned, the internal contacts are allowed to close and make a connection, which then supplies power to the load. The characteristic clicking noise that is produced when the arm is moved is a result of the blocking and unblocking of the contacts as the arm is rotated. This mechanism is known as make-before-break, which means a connection is being made before the previous connection is broken, thus avoiding any voltage interference.\'

The 71AS30-01-2-04S rotary switch is a great choice when it comes to reliable make-before-break circuit switching. It’s highly versatile and is one of the most popular switches amongst the industrial control sector. With each rotation of the actuator, the circuit is safely broken and reliable energized in discrete positions, enabling safe and reliable control of circuits.
