D4JL-2RFA-C5N-T

Snap action, limit switches are switches that employ a mechanism that is mechanically linked to a spring. This spring is typically used to create an impulse each time it is triggered. This impulse moves a mechanical contact to the predetermined position, thus the switch “on” or “off” state is changed. D4JL-2RFA-C5N-T is a specific example of such a snap action, limit switch.

The D4JL-2RFA-C5N-T snap action, limit switch is mainly used in applications that require a limited amount of current. It is designed to operate with a range of between 200 and 400mA, making it suitable for applications that require a low power signal, such as door and window position sensors, limiters, and speedometers. It can also be used in applications that do not require activation, such as factory automation systems and HVAC systems.

The working principle of a snap action, limit switch is based on the mechanical movement of a plunger when the circuit is activated. When the current to the switch is higher than the specified threshold, it causes the plunger to move. This movement in turn triggers a predetermined switch position and the contact is opened or closed. This action is what causes the switch to snap and then return to its original position. The switch is designed to always return to its original position, meaning that if the current drops below the set threshold, the switch will reset itself to the “off” position.

The D4JL-2RFA-C5N-T snap action, limit switch is a reliable and easy to install switch that is suitable for a range of applications. With its low power rating, it is well suited for use in automated systems and HVAC systems that require accurate and repeatable switch activation. It is a cost effective solution and is easy to install and maintain, making it a popular choice for both industrial and consumer applications.
