Snap action switches are an important type of limit switch, and the 1EN417-R3 switch is a good example of this type of switch. It is designed to be used in a variety of applications, such as machinery control, automatic door and window control, HVAC systems, and many more. This article will explain the 1EN417-R3 application field and working principle.

Application field

The 1EN417-R3 is a highly versatile switch and can be used in a variety of applications, including machinery control, automatic door and window control, HVAC systems, and many more. It is designed to provide reliable switching in an environment with temperatures from -40°C to 85°C. Additionally, the switch features robust construction that makes it suitable for harsh environments.

The 1EN417-R3\'s versatility makes it suitable for a wide range of applications including:

• Automotive - power windows, locks, shifters, sunroofs and other functions.
• Industrial - Proximity sensing and position sensing on automated machines.
• HVAC - Temperature and humidity control on air conditioning units.

Working Principle

The 1EN417-R3 switch functions by utilizing snap action. This is a type of mechanism in which the contact changes its position very quickly when the demand is made on the switch. The 1EN417-R3 has a pressure-pad contact design, which ensures reliable switching. The contacts are normally open until they are pressed, and then they close quickly with snapping action.

When the contacts are closed, a metal plate moves back and forth in a feature known as "abuse-lockout". This prevents false switching from accidental bumps and shocks. The switch then quickly resets when the pressure pad is released.

The 1EN417-R3 is designed for both AC and DC applications. It uses micro-load switching, and can handle up to a 10A load. The electrical rating for this switch is 5A at 125/250V AC and 0.3A at 24V DC.

The 1EN417-R3 is also designed with adjustable trip and release points. This allows the user to set the trip and release points to the exact point they need, ensuring the switch is reliable in their application.

Conclusion

The 1EN417-R3 is a highly versatile snap action switch. It is designed to handle a variety of applications and can handle both AC and DC applications. Its robust construction and adjustable trip and release points make it a reliable option for many environments.
