Additionally, this switch can also be used in irrigation and agriculture systems.

Working Principle

The D4JL-2QFA-D5 snap action micro switch works on the principle of a metal plunger which is driven by a spring. When an external force is applied on the metal plunger, it moves to a certain position according to the nature of force and the spring energizes and unlocks the switch contacts. As the switch contacts start to separate, an electric current is drawn through the contacts, thus activating the switch. Thus, this switch works via mechanical means.

This switch is designed with advanced features such as a resistance to dust and water, longer service life, higher contact life, and higher contact accuracy. This switch is also notable for its high power consumption and is also suitable for safety indications. Moreover, the switch is resistant to vibration and shock, offers longer durability and accuracy, and provides superior performance. With its low power consumption and easy maintenance, the D4JL-2QFA-D5 snap action micro switch can be used in many application areas.
