The Rotary Switches: The MRA403-BG Application Field and Working Principle

Rotary switches are a type of switch that is used in a wide range of applications, including office equipment and consumer electronics. They are commonly found in radios, TVs, and other everyday items. The MRA403-BG is a rotary switch that is designed for general purpose use. In this article, we will discuss the application field and working principle of the MRA403-BG. The MRA403-BG is a 4-position rotary switch which is designed for general purpose use and is the perfect solution for applications such as PC power supply voltage selectors, off-hook bus isolation switches, test systems and low current control applications. This switch offers 4 positions, with each position offering one of four settings: Off, On, NC, and NO/NC. As a result, this makes it an ideal switch for a range of applications. One of the most useful features of the MRA403-BG is its choice of contact form, be it traditional snap-acting silver contacts or no-contact, solid-state reed switches. This switch also features a range of rated currents, including 2A, 4A and 5A, allowing you to select the best rated current for your application. The MRA403-BG also comes with a voltage range of up to 30V, which ensures reliable switching performance. In terms of its working principle, the MRA403-BG works by utilizing an internal plunger which is operated by the rotational position of the switch. As the plunger moves, it makes contact with the appropriate contact points, completing a circuit. This is known as a Rotary Switch. The plunger is held in position by springs and is designed to operate without fail for the life of the switch. The plunger can also be adjusted for the level of torque required, which ensures the switch always operates correctly. The MRA403-BG is constructed from a durable material and is designed to be reliable and easy to work with. The switch is also small enough to fit into any convenient space, making it an ideal solution for applications where space is at a premium. Furthermore, this switch is UL listed and is therefore compliant with safety regulations. In conclusion, the MRA403-BG is a reliable and durable rotary switch that is perfect for applications requiring a 4-position switch. Its choice of contact form and rated currents, along with its small size and UL listing, make it ideal for a variety of applications. Its working principle uses an internal plunger which is controlled by the rotational position of the switch to make contact with the appropriate contact points.
