D2F-FL3-A1

Snap action limit switches are a widely used, versatile form of electromechanical switch. They work on the principle of a mechanical assembly that can be compressed by an outside source, and that when deactivated, a spring-loaded lever will snap the switch back into its inactive position.

The D2F-FL3-A1 is a popular type of snap action limit switch which uses a single armature assembly. This armature consists of a ferromagnetic disc, connected by a spring to a plunger that triggers the switch. When an external force is applied to the armature, the plunger is pushed inwards, compressing the spring and producing an electrical output. When the external force is released, the spring will push the plunger outwards, returning the switch to its inactive position.

The wide range of applications of the D2F-FL3-A1 includes automotive, industrial, and medical settings. In automotive settings, it may be used to measure a car\'s speed, or as a tilt switch which signals when a vehicle goes over a predesignated angle. In industrial settings, it can be used as a proximity switch to measure the distance between two objects, or as a limit switch which signals when a machine reaches a predefined point. Finally, in the medical field, it can be used as a pump switch, to control the rate of infusion of certain medicines.

The versatility of the D2F-FL3-A1 makes it an invaluable tool in a variety of settings. In addition to its broad range of applications, the snap action mechanism ensures quick and reliable switching, and the simple armature assembly makes it easy to use and maintain.
