Snap Action, Limit Switches

39EN4-3B Application Field and Working Principle

Snap action,limit switches are specialized types of switches that are designed to detect the presence or absence of a physical object. They can be found in a wide variety of applications including industrial, commercial and domestic use. The most common uses are to detect when something has passed a certain point or to trigger an action at a certain point. A 39EN4-3B snap action, limit switch is a particularly specialized version of this switch which can be used for a wide range of applications.

The 39EN4-3B snap action limit switch is constructed from a robust metal construction which gives it strength and durability in a range of environments. It is designed to operate from a range of angles of rotation, making it an ideal choice for applications where the switch operates from a skewed position or at a shallow angle. The 39EN4-3B is an SPDT (single-pole, double-throw) type switch, meaning it has three contacts; two for switching and one for grounding.

The 39EN4-3B snap action limit switch works by utilizing a moving arm which is held in one position by a self-locking mechanism. When the arm moves into contact with the switch contacts, an electrical circuit is completed and the switch is activated. The arm is held in place with a tension spring and when it moves into contact with the switch contacts, the current is completed.

The 39EN4-3B is commonly used in a range of applications such as access control systems, safety systems, stop/start systems and counting systems. It can be used in any situation where a reliable and accurate contact must be present to operate a system. For example, it could be used in an elevator system to prevent the lift from faltering between floors or in a conveyor system to stop the operation when the product has been delivered.

The 39EN4-3B is a reliable and accurate switch, making it a popular choice for a range of applications. It is strong and durable, so it can be used in a wide variety of environments without fail. Additionally, its self-locking mechanism ensures that it stays in place, even under extreme conditions. This makes it a great choice for any application where accuracy and reliability are essential.
