4EN87-6

A 4EN87-6 snap action, limit switch is an electromechanical device intended for machine applications where the desired action is enabled or disabled by an operator. It is commonly used to control the turning on or off of a machine, switch between different settings, or to alter operating conditions in response to changes occurring in its environment. A snap action, limit switch consists of two main parts: the actuator and the switch itself.

Actuator

The actuator of a 4EN87-6 snap action limit switch is the component responsible for physically triggering the switch. It is usually a button, lever, or roller, and transmits mechanical motion such as pushing or pulling to the switch. This motion is then translated into an electrical response within the switch. Different actuators have different specifications; each will have its own range of actuation forces and speeds, as well as a defined range of travel, or distance over which the switch will be triggered.

Switch

The switch in a 4EN87-6 snap action limit switch is the component that translates the actuator’s mechanical motion into an electrical response and communicates it to the machine or device. The switch’s electrical contacts are the central component of its functionality, as they are responsible for disabling or enabling the desired action. The number and type of electrical contacts, as well as their maximum current rating, vary depending on the model of switch as well as the particular application for which it is intended.

Working Principle

The working principle of a 4EN87-6 snap action limit switch is quite simple; the actuator is pushed or pulled to close the switch’s electrical contacts, allowing an electrical connection to be made between two separate points. This connection can then be used to activate a device, such as a motor, or to trigger a particular action. The switch will remain in this position until it is acted upon again, either by further pressure being applied to the actuator, or by the force of gravity once it has been released.

Application Field

4EN87-6 snap action limit switches are most commonly used in machine applications; they are used to enable or disable a machine’s functionality, switch between different settings, or to alter operating conditions in response to changes in its environment. They are commonly found in automation and control systems, air conditioning and refrigeration systems, household appliances, and electrical and electronics applications.

In summary, 4EN87-6 snap action limit switches are electromechanical devices used to enable or disable a machine’s functionality. They consist of an actuator and a switch, with the actuator being responsible for physically triggering the switch and the switch in turn translating the mechanical motion into an electrical response. This electrical response can then be used to activate a device or trigger a particular action. They are most commonly used in machine applications, where they are used to enable or disable a machine’s functionality, switch between different settings, or to alter operating conditions in response to changes in its environment.
