Introduction

Rotary switches are very common and widely used in many fields for its features of reliability, robustness. In general, rotary switches are used to connect multiple circuits making a path through desired number of poles and positions. 44M45-08-1-03N is one of the rotary switch designed by our company, it is widely used in industrial, automotive, medical and other related fields. This article would explain the application field of 44M45-08-1-03N and its working principle.

Application Field of 44M45-08-1-03N

44M45-08-1-03N is a high performance rotary switch widely used in industrial, automotive and medical applications. It has strong robustness, high reliability and low cost, making it an ideal choice in harsh environment where switching is needed. In industrial application, the 44M45-08-1-03N is often used to control low current signals in process control systems, such as in on-off switch, interlock control, and display control. In automotive applications, it can be used as an automobile heater switch, parking brake switch and other switches. In medical applications, the rotary switch is used in devices such as medical ventilators, monitors and infusion pumps.

Working Principle of 44M45-08-1-03N

The 44M45-08-1-03N is a single pole, 5-position rotary switch with an isolated "OFF" position. It has five switch poles and six circuits. The switch has three concentric rings, which are the switch rotor (a multiple-turn rotary switch), resistive element, and the contact arm. The switch rotor is the outermost concentric ring that is rotated to select the circuit desired. When the rotor is rotated, it moves the resistive element, which changes the resistance of the circuit. When the switch is rotated, the contact arm, which is connected to all the normally open contacts, is pushed either in or out to make the switch circuits. The contacts are connected to the pole and to the terminals, which complete the circuit.

Conclusion

The 44M45-08-1-03N rotary switch is a reliable, robust, and cost-effective switch, which is suitable for various applications, such as industrial, automotive, and medical. The working principle of the switch is based on its three concentric rings - the switch rotor, the resistive element, and the contact arm which is connected to all the normally-open contacts. The switch ensures reliable, continuous on-off switching in harsh environments.
