Rotary switches are commonly used in many applications and come in a variety of sizes, shapes, and styles. The 71MB30-03-2-03N is one such switch. It is a miniature rotary switch, designed to provide mechanical switching in miniature packages.

The purpose of a rotary switch is to allow a user to select one or more specific electrical circuits or contact points by rotating the switch, or moving the switch’s rotary knob. By changing the position of the switch, an electrical contact is open or closed, creating a new circuit. This simple mechanical action is what allows for a wide variety of applications.

The 71MB30-03-2-03N miniature rotary switch is specially designed to be used in applications where the control is kept small and compact. With a compact size of only 9.5mm x 6.3mm, this switch is ideal for environments where space is at a premium. It also has a rating of 0.4VA at 25V DC, meaning it can handle a low power requirement.

In terms of construction, the 71MB30-03-2-03N has an epoxy resin-sealed contact system to prevent any short circuits or electric shock when the switch is being used. This makes it well-suited for delicate applications where safety is a priority. The switch also features a two-piece die-cast case made of brass or stainless steel, which makes it durable and able to withstand long-term operation. Additionally, the switch also features a UL and C-UL rating of 150C, indicating it is safe to use in a wide range of operating environments.

When it comes to the working principle of a rotary switch, it is important to note that the switch must be properly wired in order for it to work correctly. This involves connecting the three terminals (common, normally open, and normally closed) to the desired electrical circuit. As the switch is rotated, one of the terminals will create a connection and the other will be disconnected. This will cause the circuit to open or close, depending on the position of the switch.

The 71MB30-03-2-03N switch can be used for a wide range of applications. It is often used in industrial and electronics applications, as well as in medical equipment and telecommunication systems. The switch’s small size and durable construction make it ideal for many types of operations, including those that require high accuracy and reliable operation. Due to its versatility, the 71MB30-03-2-03N switch is a popular choice for many types of applications.
