The 71MBS30-01B05S is a high-performance rotary switch specifically designed for severe industrial applications. It is equipped with a mechanical actuator and multiple terminals to provide reliable electromechanical operation for a variety of applications. In this article, we will discuss the application field and working principle of the 71MBS30-01B05S.

Application Field
The 71MBS30-01B05S is typically used as a control switch in industrial automation systems. It is specially designed for long-term reliable operation in harsh industrial environments, such as highly corrosive atmospheres, extreme temperatures, and vibrations. It is commonly mounted on the control panels or control cabinets of process control systems and is used to switch between multiple control signals. This switch is also used to select different working modes in automatic or semi-automatic systems.

Physical Structure
The 71MBS30-01B05S is constructed with a mechanical actuator and multiple terminals. The actuator is a specially designed mechanism with a plastic case and a metal shaft. The shaft is rotating via a drive mechanism and has different positions for each of its terminals. In operation, the position of the shaft determines which of the terminals are connected. It has a life expectancy of millions of cycles and can be used for long-term reliable switching operation.

Working Principle
The working principle of the 71MBS30-01B05S is based on its physical structure. When the shaft is rotated, it causes the different terminals to be connected with each other in a certain order. In this way, it is able to control the flow of electric current or control signals. Depending on the type of control system, the switch can be used to operate a variety of devices such as motor starters, contactors, relays, and motor controllers.

Conclusion
The 71MBS30-01B05S is a high-performance rotary switch designed for industrial applications. It is constructed with a mechanical actuator and multiple terminals, and its working principle is based on the physical structure of the switch. This switch is typically used to switch between multiple control signals and select different working modes in automatic or semi-automatic systems. Thereby, it ensures reliable electromechanical switching operations in industrial automation systems.
