Rotary Switches

Rotary switches are commonly used in circuits to control multiple functions with a single control. A rotary switch is an electromechanical device that has multiple positions and uses a rotating contact arm to actuate switching elements. In some cases, the contact arm may be moved between positions with the assistance of a motor, while in other applications, the contact arm may be manually operated.

The 71EDF30-03-1-AJN rotary switch is a 12-way rotary switch with a 30º mechanical rotation between switching positions. This switch has several advantages over other types of rotary switches including low contact resistance and a sealed housing. The rotary switch is designed to operate in hazardous environments and is rated to operate from -25 ºC to +65 °C.

Application Field

The 71EDF30-03-1-AJN is a versatile rotary switch that can be used in a variety of applications. It is typically used for power switching and control in a variety of industrial, commercial, and domestic applications. It can be used in a variety of circuits including lighting control, motor control, switching between multiple power sources, switching between multiple circuits, and controlling multiple functions in audio, video, and communication systems.

Working Principle

The rotary switch typically consists of a circular, spring-loaded switch contact arm that is actuated by the rotation of a knob, wheel, lever, or other operating element. The contact arm moves between switching positions determined by the mechanical stop positions. When the contact arm reaches the desired position, it makes contact between the switch terminals and the output terminal, completing a circuit.

The switch is made of a rotating contact arm and a fixed contact plate. The contact plate has different sets of contacts with each set corresponding to one of the switch’s positions upon rotation. As the switch is rotated, the contact arm moves the contact plate and makes contact between the covers and the output contacts. This completes the circuit and allows electricity to flow from the input to the output terminal.

Conclusion

The 71EDF30-03-1-AJN rotary switch has multiple applications in a variety of markets. It is commonly used for power switching and control in hazardous environments and is designed for use with multiple power sources, circuits, and functions. It operates using the principles of a rotating contact arm that makes contact with the fixed contact plate and controls the flow of electricity between the in and out terminals.
