Rotary switches (44M90-02-2-02N), also known as multi-pole rotary switches, are electromechanical components with many uses. The rotary switch can be used for applications like dimming the lights in a room, enabling and disabling power supplies, and providing control over relays. The switch\'s rotational motion is utilized to make contacts between the two metal surfaces.

Rotary switches come in many varieties, including 1-pole, 2-pole, and 4-pole, depending on the specific application needed. On the poles, the switch will have different contact configurations and contact steps, associated to their application. Generally speaking, the contacts will be either single- or double-throw.

To understand the working principle of a rotary switch, it is important to know the different parts a rotary switch is composed of. Generally, a rotary switch consists of a movable slide, known as the brush, and a stationary contact. There is also an actuator, which connects the switch to its associated system. The switch is then connected to a fixed base. This forms the frame that holds all the pieces together.

The switch works by connecting and disconnecting the contact on the brush as it slides over it. The brush is attached to the actuator, which rotates when actuated by an external source. The rotation creates an alternating current which, in turn, causes the contacts to connect and disconnect, depending on the desired outcome.

Rotary switches are designed to operate quickly, providing a response time of 0.1 of a second, while maintaining high reliability. They are also designed to be used in harsh environments, as they are resistant to dust, dirt, and grime. They are built to be very durable and long-lasting, making them an ideal choice for applications where quick response and reliable operation are needed.

44M90-02-2-02N rotary switches are commonly used in industrial applications such as heating, ventilation, and air conditioning (HVAC); engineering and automotive systems; medical, laboratory, and scientific equipment; and communications systems. They are also used in consumer products such as household appliances, electronics, and power tools.

While other types of switches may be used for the same purpose, a rotary switch offers the benefit of being relatively small, simple to operate, and reliable. It is simple to configure and use, and requires very little maintenance. The switch can be set up in a manual or automated mode and is suitable for both indoor and outdoor applications.

In conclusion, rotary switches such as the 44M90-02-2-02N are versatile components that can provide reliable operation and quick response in a wide variety of applications. They are easy to configure and operate, and require minimal maintenance. Furthermore, they are designed to operate in harsh environments and are robust enough to withstand the toughest conditions. As a result, rotary switches are an ideal choice for many industrial, commercial, and consumer applications.
