Rotary switches, also known as rotary selectors, are electromechanical components that are used to control the flow of electricity in an electric circuit by rotating a knob or handle. The 44HG45-01-1-02N is an example of such a rotary switch. It is a 4-pole, double-throw, knob-operated rotary switch. In this article, we will discuss the application field and working principle of the 44HG45-01-1-02N rotary switch.

Application Field

The 44HG45-01-1-02N rotary switch is a versatile and durable switch that can be used in a variety of applications. It is commonly used in audio systems, amplifiers, carrier communication systems, and various other types of industrial control systems. It is constructed with a die-cast aluminum housing and a knob-operated mechanism that is capable of switching up to four circuits between two positions.

The 44HG45-01-1-02N switch also features a screw-type locking mechanism, making it suitable for frequent switching operations. The enclosure is designed to be resistant to dust, oil, and water splashes, making it suitable for use in tough operating environments. Additionally, the contact rating is 6A/250V, making it suitable for switching low-voltage AC- or DC-powered circuits.

Working Principle

The 44HG45-01-1-02N rotary switch operates using a unique contact system consisting of four separate contacts. Each contact is connected to its own pole, and when the knob is turned, the contacts move together along a single common axis to establish or break connections between the poles. The contacts are self-cleaning and come with silver-plated contact points that provide dependable, low-resistance contact making and reliable switching.

The knob is connected to a cam, which controls the movement of the contacts. This cam is mounted on a coil spring, and as the knob is rotated, the contacts are opened or closed. The rotating motion of the knob also triggers a switch, which is used to detect the position of the switch. This helps to provide a signal when the contacts are opened or closed, ensuring accurate switching operation.

The 44HG45-01-1-02N rotary switch is an effective and reliable switch for controlling a variety of electrical circuits. With its resistance to dust, water and oil, and its ability to switch up to four circuits between two positions, it is a powerful and versatile tool for a wide range of applications.
