Introduction

Pushbutton switches are considered a basic switching device that can control and activate an electrical circuit. Pushbutton switches can be found in countless applications, ranging from computers and electronics to process control, power instrumentation, and even in vehicle applications. The 38BC-0-V-3-S is a particular pushbutton switch. In this article, we will look at the application field and working principle of this pushbutton switch.

Application Field

The 38BC-0-V-3-S pushbutton switch is a popular choice for industrial and commercial applications. The switch has a low profile, making it suitable for tight spaces, and is rated to IP67 – suitable for applications exposed to elements such as rain, snow, and dust. It is also particularly resistant to shocks and vibrations.This switch is often used in applications such as medical instrumentation, vending machines, and industrial control systems. The switch has a contact load of 4A at 24V AC/DC, making it suitable for use in mains-powered applications. It is also UL approved, making it suitable for use in building control systems and hazardous environments.The switch is designed such that it can be mounted in two different ways. It can be mounted with a threaded tubing, or flush mounted with a snap-lock clip. This makes it very versatile and suitable for a range of applications.

Working Principle

The 38BC-0-V-3-S pushbutton switch operates on the principle of inductive switching. When the button is pressed, a magnetic coil is energized, inducing a current in the switch. This current is enough to keep the switch in the closed position as long as it is pressed. When the button is released, the current stops and the contacts return to the open position.The switch is designed such that the current is only energized when the switch is closed, protecting it from damage due to prolonged current flow. The rating of 4A at 24V AC/DC means that it will handle a moderate load without overloading the contacts.

Conclusion

The 38BC-0-V-3-S pushbutton switch is a highly versatile and reliable switch suitable for a range of applications. It is designed such that it is suitable for mains-powered applications and is resistant to shocks, vibrations, and dust. The switch is UL approved and operates on the principle of inductive switching. The rating of 4A at 24V AC/DC makes it suitable for handling moderate loads.
