A3UL-TBU-2A1C-5M-S

Pushbutton switches are commonly found in the daily life and have many applications, ranging from home appliances to industrial settings. The A3UL-TBU-2A1C-5M-S is a type of pushbutton switch, which is widely used in industries due to its easy installation, space-saving design, and long service life. This article will discuss the application field and working principle of this pushbutton switch.

Application Field

The A3UL-TBU-2A1C-5M-S pushbutton switch is suitable for industrial applications, especially in the automation control, security alarm, remote control, and safety circuits. This switch can be 2 or 4-position normally open, normally closed, and combination selectable with no mechanical interlock as standard. It has a good effect on energy-saving, environmental protection and cost savings, which makes it popularly used in production lines of various industries.

In addition to industrial applications, the A3UL-TBU-2A1C-5M-S pushbutton switch is also popular in the home appliances and lighting control sectors. This switch can be used to control the on and off of lighting, signal rotation and detection of rotary speed. Thanks to its good performance and small size, it is highly recommended as the replacement of other electrical switches.

Working Principle

Under the same conditions, the closed A3UL-TBU-2A1C-5M-S pushbutton switch has two positions, that is, normally closed (NC) and normally open (NO), and the circuit is shown in the picture. The NO contact has a closed circuit when it is pressed and released, and the NC contact can be pressed normally. It is connected to the NO contact to form a closed circuit.

In addition, the A3UL-TBU-2A1C-5M-S pushbutton switch has two other positions: double-click normally open (DNO) and double-click normally closed (DNC). The two last positions are placed between the NC and NO positions. When it is pressed, the electrical connection is switched from NC to NO, while releasing the connection is reversed.

Conclusion

To conclude, the A3UL-TBU-2A1C-5M-S pushbutton switch is widely used for industrial automation, home appliances and lighting control. Its easy installation and space-saving design make it the ideal choice for projects of various sizes. Furthermore, the working principle of this switch is also discussed in this article, which helps to better understand its electrical behaviors.
