Snap action, limit switches are electromechanical devices which detect physical changes in the operating environment, such as pressure, temperature, displacement, and the like. These switches work on the principle of mechanical interaction between two elements, where one element can move against the other to form an open or closed electrical circuit. The D4E-2G21N is a snap action limit switch with actual mechanical actuator. It contains a spring-loaded contour, which comprises a U-shaped lower arm, a bar, a contact element and an actuator.

The D4E-2G21N switch works on mechanical movement causing the contact to open or close when the actuator is forced by the spring-loaded bar. As the actuator is moved, the contacts of the switch are forced away from each other, ultimately breaking the circuit. When the force is released, the spring loaded bar pushes the actuator back to its defined resting position and brings the contacts back together, thus restoring the circuit.

The D4E-2G21N limit switch can be used in a wide range of applications, such as controlling motors, signaling the presence of an object, or opening and closing a circuit. It is also suitable for use in hazardous environments as it has a high dielectric strength, a high degree of dust resistance, and is able to withstand pressure, shock and vibration. Another application of this switch is in the navigation field, where its contact arrangment can be used as a devices to sense the position of navigational aids.

When a changing physical environment needs to be monitored, a limit switch such as the D4E-2G21N can be used to detect the change and activate whatever mechanism is required. This type of switch is particularly suitable for applications that require quick responses, such as in industrial control systems, where the spring mechanism of the D4E-2G21N ensures fast snap action.

In conclusion, the D4E-2G21N snap action limit switch has proven to be an ideal solution for a wide range of applications, from detecting physical changes in the environment, to navigating and signaling the presence of an object. The quick-acting spring mechanism ensures reliable and consistent operation, and the switch’s ability to withstand the elements, pressure and vibration gives it the added advantage of being highly reliable in hazardous environments.
