Rotary switches are the oldest type of electrical switch and can be found in everyday items such as light switches, fan speed controls, and motor starters. Their operation is based on a simple principle of opening and closing contacts when a shaft is rotated. This is achieved by moving the contacts over a series of fixed points along the circumference of the switch.

The MRA403-BB is a type of rotary switch commonly used in industrial applications. It is designed to provide reliable switching performance in applications requiring a large number of switching operations. It is capable of switching up to 10 Amps of current with a contact rating of 6A/250V AC.

The MRA403-BB is designed with a 4-pole architecture and has 10 switching positions. These 10 positions are divided into four sets of two poles, can be switched in any sequence without any additional components. The rotary switch also features a high level of contact pressure which provides a good contact quality and ensures reliable operation even under harsh operating environments.

The MRA403-BB operates in a simple way. As the spindle is rotated, the contact springs are brought into contact with the contact plates on the interior of the switch. As the contact springs come into contact with the plates, electrical current is passed to the respective circuit. Each time the spindle is rotated, the contact springs are moved from one contact plate to another, thus creating a new electrical connection. The contact springs are kept under constant tension and automatically released when the spindle is turned back to its original position. This prevents the contact springs from being damaged by excessive contact pressure.

The MRA403-BB is designed to be flexible as it can be used in many different applications. It is suitable for use in control panels, generator control, testing and diagnostic equipment, and many other applications where reliable and robust switching is needed. It can also be used in industrial process control systems, such as the automated monitoring of temperature and pressure readings.

The MRA403-BB is designed with robust construction and can withstand harsh environmental conditions. It is also designed with a wide variety of mounting options to suit most applications, including flush mounting and horizontal or vertical mounting. The MRA403-BB is also UL and CE approved, making it a reliable and safe choice for use in many industrial applications.

The MRA403-BB is a reliable, robust, and versatile rotary switch that can be used in a wide range of industrial applications. With its high level of contact pressure and multiple mounting options, it is the perfect choice for applications requiring a reliable switching performance.
