Snap Action, Limit Switches

Snap action, limit switches are primarily used for the detection of motion, position and force, and are primarily used in automation applications. Snap action limit switches are the most commonly used type of limit switch and include subcategories such as toggle, pushbutton and micro switches. They are used in a wide variety of applications, including safety, machine control, positioning and sensing.

The D4N-8172 is a type of snap action, limit switch. These switches use a snap action design and have a contact construction that produces two poles in their switch. This enables the switch to perform two independent switching functions. The openings and closings of the contacts of the switch allow the actuator to move the switch between the two poles.

The working principle of the D4N-8172 is based on the principle of lever and hinge interlocking which is normally used when the switching action is automatic. When actuated, an electromechanical or mechanical force will cause the switch to move between one of its two positions. This movement will then activate the limit switch lever, which will cause an opening or closing of the switch contacts.

The D4N-8172 can be used in a wide range of applications, including the control of electric motors and other apparatus that require precise limit-switching operations. It is ideally suited for use in machinery, industrial control systems and equipment, such as compressors and blenders. They are used for electric motor control, position and speed sensing, and other applications where precise control of movement is desired.

In addition, the D4N-8172 is equipped with overload protection, which prevents undesirable current from damaging the switch. This protection is accomplished by the incorporated self-resetting thermal overload element, located in the actuator head. This element shuts off the electric current in the case of too many electric current fluctuations.

The D4N-8172 also has a high level of reliability, which is a key factor in automation. The contact arrangement is designed with a high contact force to reduce the risk of arcing or sparking, which can lead to switch failure. This robust construction and contact protection makes the switch ideal for applications in industrial automation environments where reliable switching is required.

Finally, the D4N-8172 also offers a high level of precision in terms of repeatability and accuracy. The actuator head is designed for precise location and actuation of the switch, with each individual unit being tested for repeatability and accuracy.

In conclusion, the D4N-8172 is an excellent choice for snap action, limit switch applications. It offers a high level of reliability and precision, and has overload protection to prevent damaging electric current. The switch is ideal for industrial automation applications and provides reliable and precise switching.
