Snap Action, Limit Switches

D3V16G22C26K limit switch is a type of snap-action switch which, when actuated, requires minimal torque and rapidly returns to its original position. It consists of a plunger with a spring mechanism to rapidly change the contact position when the plunger is depressed. These switches have an actuator that is either a roller, a lever or a plunger, and their contacts open and close as the actuator moves between its two positions.

Application Fields

D3V16G22C26K switches are mostly used to detect the presence and/or absence of items in a predetermined position along a given axis. For example, they are used in bottling plants to detect the level of liquid in a container, in automobile manufacturing to determine the position of a part, and in food processing plants to measure the presence of ingredients in a conveyor belt. Additionally, they are employed to sense the movement of a machinery component and to provide a controlled stop position.

Working Principle

The D3V16G22C26K switch typically works on the lever principle. It consists of a movable, spring-loaded lever which carries the contact and is mounted on moving part of the machine. When the actuator lever is pressed down, it causes the contacts to close and the current is allowed to flow through. When the lever is released, the contact opens and the circuit is broken.

The D3V16G22C26K switch also employs a snap-action phenomenon. This snap-action occurs due to the preloaded spring mechanism, when actuated, causes the switch contacts to rapidly and quickly snap to the on position and then to the off-position. This snap-action helps to detect the presence and/or absence of an object quickly and accurately.

The switching process is usually witnessed by an audible sound and detected visually. This type of switch is also known as a microswitch, because of its increased sensitivity, due to the snap action.

Conclusion

D3V16G22C26K is a type of snap-action switch which uses the snap-action concept to detect the presence and/or absence of items in a particular location. These switches have a lever, roller, or plunger providing the actuation mechanism. The D3V16G22C26K switch is widely used in industries for object detection, for motion sensing and for controlled stoppage of machinery components.
