Rotary switches are a type of switch mechanism found in a variety of electrical and electronic applications. A rotary switch is a switch with a rotary actuator or knob that makes or breaks electrical connections as it is rotated. The 71A30-01-5-02N is a single-pole, multi-position rotary switch frequently used in industrial and commercial applications. This type of rotary switch is designed with 30 positions and a 2-contact bushing.

Application Fields

The 71A30-01-5-02N rotary switch can be used in a range of applications, from low-current (A/C and D/C) circuits in low-voltage applications like home automations, lighting design, and medical control systems, to high-voltage/high-current circuits like stepping motor control systems and motor speed controllers. Switches of this design are also suitable for low-level switching of digital signals, where low-level signals need to be conditioned and routed to specific locations. This makes them popular for use in audio mixing boards.

Working Principle

At the core of the 71A30-01-5-02N rotary switch is a cylindrical shaft connected to a set of contacts. The shaft is designed with 30 contact positions around its circumference and as the shaft is rotated, it moves contacts around the circumference of the cylinder. As the shaft rotates, each contact position is alternately connected and disconnected, and the contacts can be connected only when the shaft is at a specific position. The contacts are all connected together at the base of the switch with a single contact point, called the contact bushing.

The contact bushing serves as the output point for all of the switch’s connected contacts. This means that the switch can be used to connect multiple signals at the same time and route them to a single point. When the shaft is rotated, the contacts are moved to and from the contact bushing, thus allowing the switching of multiple signals to the same point in a sequential manner.

The 71A30-01-5-02N rotary switch is an excellent choice for applications where multiple signals must be routed and switched in a controlled and consistent fashion. This type of switch is economical, reliable, and easy to use. It is also designed to accept a wide range of current and voltage levels, making it a versatile addition to many industrial and commercial applications.
