Pushbutton switches are a type of switch used primarily in electronics andfrequently used in lieu of toggle switches for convenience. From standard switches for residential utilities, to complex multi-function varieties used in complex industrial operations, pushbutton switches perform a variety of functions and can be found in countless applications. One such unit is the NE18 2A 2U EE 6AMP. This article will discuss the application fields and working principle of the NE18 2A 2U EE 6AMP.

Components

The NE18 2A 2U EE 6AMP is a single-pole, double-throw (SPDT) switch. It consists of a main contact switch, two auxiliary switches (normally open and normally closed circuits), and the button mechanism. Each switch can be actuated independently, and all the switch elements are integrated into a single, compact unit. The contact rating is 6 Amps and the auxiliary switch contact rating is 2 Amps at 250 volts AC.

Application Fields

The NE18 2A 2U EE 6AMP is primarily used in telecommunications and instrumentation. It is often used as a key switch and/or as a momentary switch to trigger or enable/disable components. It can also be used in home automation applications and in medical devices. It is a reliable, versatile switch that is capable of withstanding a wide range of temperature and humidity conditions. For example, it is suitable for use in areas subject to wet and dusty conditions.

Working Principle

When the button is actuated, the main contact switch is closed and the normally open auxiliary switch is closed. When the button is released, the main contact switch opens and the normally closed auxiliary switch is closed. This dual-action activates or enables the connected device depending on its design. For example, a key switch could be used to open or close a door lock. When the button is pressed, the main contact switch is closed and the door lock operates. When the button is released, the main contact switch opens, and the normally closed auxiliary switch is closed. In this application, the normally closed auxiliary switch could signal the alarm system that the door is closed and secure.

Conclusion

The NE18 2A 2U EE 6AMP is a robust, reliable SPDT pushbutton switch that can be used in a wide variety of applications. It has a 6 Amp main contact rating and a 2 Amp auxiliary switch contact rating, making it suitable for both commercial and residential applications. Its dual action switch elements allow for a variety of functions, such as triggering on/off switches or enabling/disabling components. It is capable of withstanding a range of temperature and humidity conditions, making it suitable for wet or dusty environments. Overall, the NE18 2A 2U EE 6AMP is a robust and versatile switch that can be used in an array of applications.
