Introduction

Rotary switches are popularly used for various applications since their invention in the early 19th century. 59HS18-02A20N, one type of rotary switch, is a normally open, single pole-double throw (SPDT) switch. It is designed to switch two circuits via one rotary knob. In this article, we\'ll discuss the application field and working principle of the 59HS18-02A20N rotary switch.

Applications

The 59HS18-02A20N can be used in many different fields. For example, it can be used in the electronic and electrical industries to control circuits and as a switch for jumper wires. This switch is widely used in testing equipment and medical instruments; it is also widely used for volume, frequency and mode control.In the military, the 59HS18-02A20N switch is commonly used in tactical weapons systems, navigation, missiles and radar systems. It is also used to switch between two circuits in telecommunications and other industries.

Working Principle

The 59HS18-02A20N rotary switch is composed of a printed circuit board, a switch mechanism, and a knob. The knob is connected to the switch mechanism, which then is connected to the printed circuit board. The switch mechanism grip the printed circuit board and makes a connection between the printed circuit board’s spring pillars and the terminal pins.When the knob is turned, it causes the switch mechanism to grip the printed circuit board and make a connection with the spring pillars and terminal pins. This allows one circuit to be connected to another circuit and the switch to be used as an on/off switch.Furthermore, the 59HS18-02A20N switch has a dustproof cover which helps to protect the switch from wear and dust. This cover also helps to extends the switch’s life and increase the reliability of the switch.

Conclusion

The 59HS18-02A20N rotary switch is a popular choice for many different applications. This type of switch is very robust and has a long life, making it an ideal choice for applications such as volume control, frequency control and mode management. Furthermore, the dustproof cover makes it suitable for many different types of environments. It is a versatile switch which is widely used in the military, electrical and electronics industries.
