Snap Action, Limit Switches are a type of electromechanical switch used in many different applications. The 38HM75 is a particularly popular version of these switches and has a number of excellent features. This article will discuss the application field of this switch and its working principle.

Application Field of 38HM75

The 38HM75 snap action, limit switch is commonly used in machine building, industrial applications and process control. It is best suited to these applications due to its reliability, durability and long service life. Many of these applications require a switch that can handle periods of high vibration and shock and the 38HM75 is ideal for this, as it has a high level of robustness.

It has also found use in HVAC applications, as its versatility makes it well suited to controlling airflow. It can be used in combination with a pressure switch for detecting changes in pressure, making it ideal for controlling air conditioning and ventilation systems. It also makes an excellent choice for use in alarm systems, as it can detect any movement within its range and activate an alarm if necessary.

The 38HM75 is also popularly used in motor-driven equipment and industrial machinery. Its reliable operation means that it can be used for controlling the activation, deactivation and emergency shutdown of machines in process control. It is also suitable for use in applications where a safety switch is needed, as it can detect the presence of objects and shut down any machinery if necessary.

The 38HM75 switch range has also been used in the medical industry and applications such as medical imaging and robotic surgery. Here, its versatility and sensitivity make it an ideal choice as it can monitor different processes and switch them on or off as and when needed.

Working Principle of 38HM75

The 38HM75 snap action, limit switch effectively uses a physical mechanism to move a lever, which in turn activates a micro-switch, to control a number of different processes. When the lever of the switch is moved, the contact points of an electrical circuit are connected, thus allowing current to flow from one point to another.

The snap action limit switch has a special feature that sets it apart from other switches. It is designed to snap back into its original position after the lever is moved, thus disconnecting the contact points of the electrical circuit. This return movement triggers a reset process, thus allowing the switch to reset itself and safely return to its non-active position.

The 38HM75 switch is also equipped with a range of additional safeguards, such as adjustable over-travel and adjusted thrust force. These features ensure that the switch will remain within its optimal operating range and will not be overstressed during operation, thus ensuring reliable and consistent switching performance.

The 38HM75 is designed to operate within a wide range of applications. Its robust construction ensures it can handle periods of high vibration and shock, making it suitable for use in industrial and factory applications. Its versatility also means that it can be used in medical applications and for controlling processes in motor driven equipment.

In summary, the 38HM75 snap action, limit switch is an excellent choice for a range of different applications, due to its reliability, durability, variable size and range of safeguards. It is best suited to industrial and process control applications, but can also be used in medical applications and HVAC systems. Its excellent design means that it is a reliable and durable device, and its snap action return mechanism ensures that it can reset itself into its non-active position as and when required.
