Rotary Switches

Rotary switches are widely used in the electrical and electronic products industry. They are a type of switch that uses a rotating mechanism to control the flow of current or other electrical signals in a circuit. In this article, we will take a look at the 71MBS30-04B07S rotary switch, its application fields and working principles.

Application Fields of 71MBS30-04B07S Rotary Switch

The 71MBS30-04B07S rotary switch is an electromechanical part used to control current in a wide range of applications. It can be used in the industrial automation, automobile, aerospace and automotive sectors for a variety of operations, such as:

• Controlling the speed of motors, pumps and other mechanical devices
• Switching between multiple electrical circuits
• Switching between different power sources
• Selecting pre-defined operating modes

The 71MBS30-04B07S rotary switch is well-known for its durability and long service life. It is rated for up to 1 million mechanical operations and up to 100,000 electrical operations. It can also withstand a wide temperature range, from -20°C to +85°C.

Working Principle of 71MBS30-04B07S Rotary Switch

The 71MBS30-04B07S rotary switch operates on the principle of a mechanical commutator. It contains a round contact plate (or "star wheel") that is turned by an external knob. This star wheel contains several sets of contacts that can be connected or disconnected as it rotates. When the external knob is turned, the star wheel rotates and the contacts are mechanically commutated to create the desired circuit.

The rotary switch also contains a spring-loaded plunger that ensures the contacts are always properly aligned and the circuit remains closed when the knob is rotated. When the knob is released, the plunger pushes against the contacts and completes the electrical circuit. This ensures the circuit will not be interrupted while switching between different settings.

Conclusion

The 71MBS30-04B07S rotary switch is an electromechanical component used for controlling the current in a circuit. It is rated for up to 1 million mechanical operations and up to 100,000 electrical operations and can be used in a variety of industrial and automotive applications. It operates on the principle of a mechanical commutator, which uses a rotating star wheel and a spring-loaded plunger to switch between different settings.
