D4C-3401

Snap action, limit switches are a type of environmental and mechanical switch that are used to detect the physical presence or lack of presence of an object in a particular environment. Such switches are typically used in assemblies where a switch performs a certain function, such as detecting when a water pipe is blocked or when a pressurised pipe has been punctured. The D4C-3401 is a snap action, limit switch with many applications, including temperature and pressure detection, flow and level detection, position detection, and more.

Application Field

The D4C-3401 snap action, limit switch is used in a variety of applications requiring mechanical operation of a switch. This switch is commonly used in industrial environments, such as in manufacturing processes and power plants. In addition, the D4C-3401 is suitable for hazardous and wet locations which require a water-proof switch. It has a vibration-resistant PU cable that is designed to withstand millions of operations. The switch is also suitable for low temperature applications, making it a versatile choice.

Working Principle

The D4C-3401 snap action, limit switch is designed with a unique snap-action mechanism. The mechanism is based on an electrical contact trip in the form of a spring-loaded snap disk. When a difference in pressure or other change in the environment is sensed, the snap disk is pushed against a stationary contact and completes the circuit. This creates a snap-action mechanism, which produces a rapid switching action with an extremely low contact resistance. Once the switch is activated, it will remain engaged until manually reset or until the setting force is removed.

The D4C-3401 snap action, limit switch offers several advantages. It is simple, robust, and economical. It also provides increased safety, as it will disengage in situations where the contact forces are raised beyond normal levels. This limits the amount of current that may flow through the contacts, preventing any serious damage to the circuit. In addition, the switch has excellent position repeatability, meaning that it can be used with great accuracy in applications requiring precise switching action.

In conclusion, the D4C-3401 is an excellent choice for a wide variety of applications that require reliable mechanical switching action. With its robust construction and versatile design, this snap action, limit switch is more than capable of delivering reliable switch operation in even the most demanding of environments. In addition, the switch provides increased safety, as it is designed to fail safely in the event of an overload or over-voltage. Thus, the D4C-3401 is a reliable choice for a wide array of applications.
