Snap action, limit switches are electromechanical devices used to activate or deactivate a circuit when a physical contact is reached. It is a type of switch which often utilizes a small moving element that opens or closes the connection when a physical force is applied. D4N-4B25 Limit Switch is one of the models that are widely used in a few industries.

This limit switch is a Single pole double throw (SPDT) snap action switch with a 250V 15 amp rating. It is an affordable device, with prices ranging from 5-8 dollars, depending on the retailer. In comparison to many limit switches, it is a very compact design being only 6.25 inches long, and it has a screw termination.

D4N-4B25 Limit Switch is mainly used in industrial automation. It is mainly used as part of automated line control where their physical contact can be used to detect location, position, count and confirm other information on the line system. When the device is moved to a certain point it will produce an electrical signal which will allow the processor to send a new set of instructions. This can be used in industries such as the automotive sector, factory automation, medical technology and robotics.

The working principle of D4N-4B25 Limit Switch is based on a lever-operated switch. It consists of two electrical contacts that are connected to an actuator. The actuator is connected to a lever arm which is operated and lifted or lowered by a mechanical force.When the lever arm is raised or lowered it will close the switch contacts, which will in turn activate the circuit. When the lever arm is released it will open the switch contacts, which will in turn deactivate the circuit.

The actuator of the D4N-4B25 Limit Switch is normally spring loaded, which will shift back to the original position when the mechanical force is removed. This ensures that the switch will always return to the neutral position, thus ensuring a reliable and safe operation. The spring is adjustable so that the force required to open or close the switch can be adjusted to suit the application.

The D4N-4B25 Limit Switch is also designed for high reliability, as it has a long life expectancy. It can withstand high temperatures, moisture and vibrations. It is designed to be insensitive to dirt, dust and chemical contaminants,which makes it ideal for use in harsh industrial environments. Additionally, the device has a quick and sensitive action, which makes it suitable for applications that require a quick response time.

In conclusion, the D4N-4B25 Limit Switch is an affordable, reliable and versatile device that can be used in a wide range of applications in industries such as automotive, factory automation, medical technology and robotics. It is a single pole double throw (SPDT) snap action switch with a 250V 15 amp rating and a long life expectancy. This limit switch is designed to be insensitive to dirt, dust and chemical contaminants, and it has a quick and sensitive action which makes it suitable for applications that require a quick response time.
