Pushbutton switches are the most commonly used devices in many everyday appliances. Whether it\'s a phone, a computer, or any other device, they are all likely to have a few pushbutton switches in it. The E 903 is no exception. It is a high-performance device specifically designed for switches that require prolonged contact and/or instantaneous contact, as well as switches that require quality contacts even when subject to vibration and shock. In this article, we will discuss the application fields of the E 903 and its working principle.

The E 903 is commonly used in industrial applications, including control panels, instrument controls, and automation systems. In a control panel, the E 903 provides a reliable way to control a process or system—and it can do so even in harsh or hazardous environments. For example, the E 903 can survive temperature extremes and is rated for operation from -40 degrees Celsius to +105 degrees Celsius. Furthermore, it is resistant to dust, dirt, and water, so it can be safely used in wet or dusty areas. In instrument control applications, the E 903\'s reliable contacts are essential for accurately reading the position of switches and other input devices. Lastly, in automation systems, the E 903\'s ability to be used in either lengthy or instantaneous contact can be used to achieve all manner of automation tasks.

The working principles of the E 903 are quite simple. It uses an electrical contact system where two metal parts are connected through a spring-loaded connection. When the switch is pressed, the metal parts come into contact and electricity is conducted between them. When the switch is released, the metal parts become separated and the electricity is cut off. This mechanism is reliable and durable, so it can be used for a long time without needing to be replaced.

Overall, the E 903 is a reliable and high-performance device that can be used in a wide variety of applications. Its simple working principle means that it can be used with confidence and its rating for extreme temperatures means that it can be used even in the most hostile environments. With its reliable and durable contacts, the E 903 is an ideal device for controlling processes, reading the position of switches, and performing automated tasks in industrial applications.
