D4N-4187

Snap action, limit switches are a type of electrical switch that is used to limit the distance of travel as well as the position of a movable object. The D4N-4187 switch is designed specifically for this purpose, and works in a variety of applications.The primary purpose of the D4N-4187 switch is to control the position and movement of movable arms, and to limit the way in which they move. This type of switch uses a special type of contact arm called a snap-action arm that snaps into place when the arm reaches a predetermined distance.The contact arm of the D4N-4187 switch is spring-mounted so that when the arm reaches its limit, the arm snaps into place. This ensures that the switch stays in place even when the arm is not in use, and can be reset easily when needed. This type of switch is often used to regulate the positions of components in industrial machinery, and is also found in consumer applications such as vending machines.In addition to its primary use of controlling the motion of movable arms, the D4N-4187 switch is also used in safety applications. The snap-action arm is designed to break away or snap into place when a certain amount of force is applied to the arm, thus preventing injury to the user. In fact, this type of switch is often used in safety circuits for medical and industrial equipment.The D4N-4187 switch employs a "floating" contact arm to activate and deactivate the switch when the arm reaches its predetermined limit. This floating arm has two triggers that work in conjunction with each other - one to activate the switch and one to deactivate it. Depending on the manufacturer, the triggers can either be operated manually or with an external power supply.The D4N-4187 switch is also highly resistant to environmental factors such as dust, dirt, water, and other hazardous substances. It can also be mounted in a variety of different places due to its small size, which makes it ideal for applications where space is limited.All in all, the D4N-4187 switch is a versatile and reliable device that can be used in a variety of different applications. It is an important component in many safety and control systems, and is a popular choice for industrial and consumer devices.
