Snap Action, Limit Switches are actuators that are triggered when a certain threshold is reached or exceeded. D4N-1B20R is a type of Snap Action, Limit Switch that is used in many industrial and consumer applications. This article will discuss the application fields and working principle of D4N-1B20R.

The D4N-1B20R is a lever-type, isolating contact limit switch. It is designed for applications where a single-pole, double throw (SPDT) switch is required. The lever can be bottom-mounted or cap-, side-, and panel-mounted. It has a variety of electrical rating and operating temperature options, making it suitable for a wide range of industrial and consumer applications. For example, it can be used in factory automation equipment, transportation, communication and audio/video equipment, home appliances, door opening/closing control, vending machines, etc.

In terms of its working principle, the D4N-1B20R has a built-in micro switch with a lever arm linked to the actuator. When an external force is applied to the lever arm, it will press the switch, which will make or break the contact inside the switch. Therefore, the D4N-1B20R will open or close the circuit when the lever arm is activated. For example, if the D4N-1B20R is used in a vending machine, when a customer inserts a coin, the lever arm is pushed and the circuit inside the switch will be closed, signalling the machine to start dispensing products. In this way, the D4N-1B20R can be used to control the operation of a variety of equipment.

In conclusion, the D4N-1B20R is a type of Snap Action, Limit Switch that is used in many industrial and consumer applications. It is designed for applications where an SPDT switch is required, making it a versatile and reliable switch for a variety of needs. The D4N-1B20R works on the principle of a lever-activated micro switch, which can be used to control the operation of a variety of equipment. It is available in a variety of electrical rating and operating temperature options, making it a suitable choice for industrial and consumer applications.
