Working Principle of 44H30-02B12N

The 44H30-02B12N rotary switch works by utilizing the principle of contact phenomenon to move the actuator from one position to the other. It utilizes two copper terminals that are connected to a metallic shaft. When the knob is rotated, the shaft moves along the helical slots and changes its position. As the shaft changes its position, the contact points make contact with the corresponding conductive pads attached to the circuit board.

These contact points then close the circuit, allowing the current to flow through the circuit and trigger the required action. This is a very reliable way of activating the circuit since it is impossible for the two contact points to make contact with the wrong pad. Moreover, the 44H30-02B12N can support multiple positions, which means that one can activate multiple functions with the same rotary switch.

Conclusion

In conclusion, the 44H30-02B12N is an incredibly versatile rotary switch that can be used in a multitude of applications. It is robust and reliable, and it is able to support multiple positions. The contact points close the circuit and allow the current to flow through the circuit, triggering the desired action. The 44H30-02B12N is most commonly used in industrial automation, electrical, and mechanical products, but can also be used for automotive, aviation, electrical and electronic instruments, and medical applications.
