Introduction

Pushbutton switches are ubiquitous in modern everyday life and are used in a wide range of applications. 39-702-E is a popular pushbutton switch that is widely used in applications such as commercial, consumer, industrial and medical. It features a two-position momentary action and a low profile design. This article will discuss the applications and working principle of the 39-702-E switch.

Applications of 39-702-E

The 39-702-E switch is commonly used in a range of control and test applications. It is especially suited for situations where space is limited or a low profile design is desired. It is suitable for use in commercial, consumer, industrial and medical applications.In commercial applications, the 39-702-E switch is often used as a keypad switch or a light switch. It is also frequently used as a start/stop switch or an emergency stop switch. In consumer applications, it is commonly used as a control switch for electric appliances. In industrial applications, the 39-702-E switch is often used for process control and monitoring. In medical applications, it is often used for medical equipment control.

Working Principle of 39-702-E

The 39-702-E switch is a two-position momentary action pushbutton switch. It has a uniquely designed low-profile construction with a button at the top and contact leafs at the bottom that actuate when the button is pressed. The contacts are made using gold-plated, corrosion-resistant silver/copper alloy leafs.When the button is pressed, the two contact leafs at the bottom close or open, depending on the designed purpose of the switch. This allows current to flow through the circuit and causes the intended action to occur. The contact leafs are spring-loaded so that they reset to their original position when the button is released. This allows the switch to be used over and over again in a reliable, consistent manner.

Conclusion

The 39-702-E switch is a popular pushbutton switch that is widely used in many applications including commercial, consumer, industrial and medical. It features a low profile design and a two-position momentary action. It works by using gold-plated, corrosion-resistant silver/copper alloy contact leafs that close or open when the button is pressed. This allows current to flow through the circuit and causes the intended action to occur.
