Snap Action, Limit Switches

The D4N-2D20 switches are a series of snap action, limit switches designed for a wide range of applications. These switches feature an adjustable actuation force for higher tolerance and better control, and provide reliable performance in electrically-intense environments. The D4N-2D20 switches are designed for both indoor and outdoor applications, and are UL and CSA certified for safety and reliability. This article will provide an overview of the application field and working principle of the D4N-2D20 switches.

Application Field

The D4N-2D20 switches are designed for a wide variety of applications. These switches can be used as limit switches in industrial machinery and heating/cooling systems, as positioning switches in pumps and fan motors, and as timers in HVAC systems. The switches are also suitable for use as alarm systems, security systems, and door entry systems. The switches can be installed in tight locations that require robust protection and IP protection up to IP68. The D4N-2D20 switches can also be used for other applications that require adjustable sensing and reliable operation.

Working Principle

The D4N-2D20 switches are snap action, limit switches. When the actuation of the switch is triggered, it snaps open or closed to send a signal or trigger a response. The switching action creates an electrical contact, which is detected and used to control the system. The adjustable actuation force of the switch allows for greater flexibility and control over the output signal. The switch also features a snap-action design which provides reliable and repeatable switching behavior.

The D4N-2D20 switches are designed to handle high power loads and are rated for use up to 30A at 600V. The switches can be used for both AC and DC systems and have an operating temperature range from -40°F to +250°F. The switching mechanism is sealed to ensure reliability and is rated for up to 1 million cycles. The D4N-2D20 switches also feature adjustable and removable mounting brackets for easy installation and maintenance.

Conclusion

The D4N-2D20 switches are a series of snap action, limit switches designed for a wide variety of applications. These switches feature an adjustable actuation force for higher tolerance and better control, and provide reliable performance in electrically-intense environments. The switches are UL and CSA certified for safety and reliability, and are rated for up to 30A at 600V. The switches are sealed for reliable operation and feature adjustable and removable mounting brackets for easy installation and maintenance.
