Pushbutton switches are common control elements that are used for many applications. One type of switch is the 40-4685-00, which offers excellent performance in many different environments. In this article, we will look at the 40-4685-00 application field and working principle.

Working Principle

The 40-4685-00 uses a contactless, non-contact design, which offers greater reliability than mechanical switches. The switch is integrated with a small electronic circuit board and a capacitor. This capacitor is used to store the electrical charge in the switch, which is what is used to activate the switch when a user pushes the button.

The capacitor is connected to two contacts, which are the “common” and “NC” contacts. When a user pushes the button, the capacitor is charged with a small current, which closes the contacts and activates the switch. This electrical current can be sent to a connected device, such as a light bulb or motor, to activate it. When the button is released, the capacitor will return back to its original state, allowing the “NC” and “common” contacts to open and deactivate the switch.

Applications

The 40-4685-00 is suitable for many applications, such as:

• Control panels and control systems.
• Medical equipment.
• Public address systems.
• Automation systems.
• Industrial control equipment.
• Alarms and security systems.

The switch is reliable and can be used in a wide range of temperatures, from -40°C to 125°C. The switch is also dust and water resistant, making it perfect for use in harsh environments.

Conclusion

The 40-4685-00 is a reliable and versatile pushbutton switch. Its contactless design makes it more reliable than traditional mechanical switches. The switch is suitable for many different applications, including control systems, medical equipment, and automation systems. Plus, it is reliable in temepratures from -40° to 125°C and is dust and water resistant.
