The 44M45-04-4-02N rotary switch is a robust and reliable rotary switching apparatus used in numerous applications, ranging from automation control to lighting, power, and audio installations. This guide will explain the application fields and working principles of 44M45-04-4-02N rotary switches in detail.

What is a Rotary Switch?

A rotary switch is a type of electrical switching apparatus which provides multiple functions depending on the amount of input power available and the number of contact points selected. It works by using a modular system with indexed cam positions or rotor blade positions. The cam turns when the applied voltage or current is either lifted or dropped, resulting in a new combination of contact points and loads being selected. Therefore, the rotary switch provides contact point selection from a series of specified positions.

Application Field of 44M45-04-4-02N Rotary Switches

The 44M45-04-4-02N rotary switch is used widely in automation control, lighting, power, and audio installations. Specifically, this rotary switch is used in applications such as control circuits, safety systems, motors and starters, and industrial control panels. In addition, it is also used in commercial and agricultural buildings, fan coil controls, as well as in burglar alarm systems.

Working Principle of 44M45-04-4-02N Rotary Switches

The 44M45-04-4-02N rotary switch works via the indexed cam positions or rotor blade positions. This means that when the applied voltage or current is either lifted or dropped, the cam turns resulting in a new combination of contact points and loads being selected. This switch typically works with a maximum AC voltage of 600 volts and a normal current rating of 40 amps. The desired number of contact points is selected by turning the cam or rotor blade until the desired number of blades engages the contact points on the rotating cam or rotor blade.

In addition, this rotary switch uses a momentary reversing mechanism which uses a three position center OFF feature on a standard four station switch. This means that when the cam is in the middle position, all contact points are disengaged and the load is turned off. However, when the switch is turned to either the clockwise or counterclockwise direction, the load is activated and the contact points are engaged.

Conclusion

The 44M45-04-4-02N rotary switch is a robust and reliable switching apparatus designed for a variety of applications. It is used in an array of applications, including control circuits, safety systems, motors and starters, industrial control panels, as well as commercial and agricultural buildings. This switch usually operates with a maximum AC voltage of 600 volts and a normal current rating of 40 amps. It uses indexed cam positions or rotor blade positions to select the desired number of contact points. In addition, it also has a momentary reversing mechanism utilising a three-position center OFF feature. All in all, the 44M45-04-4-02N rotary switch is a highly effective and reliable switching device.
