Snap action, limit switches are a type of switch used to provide electrical switching and control of a circuit and its components. The D4CC-4002 is a type of limit switch designed for performance in harsh environments and installations in extremely hazardous areas. In this article, we will discuss the application field and working principle of the D4CC-4002.

The D4CC-4002 snap action, limit switch is designed to be used in a variety of applications. It is designed to provide an electrical switch action that is quick and reliable, making it the perfect choice for applications requiring two-position or three-position switching. It is commonly used in safety and emergency stop circuits, in temperature monitoring and control applications, for motors, pumps and conveyor systems, and for reliability in harsh environments.

The D4CC-4002 snap action, limit switch has a single-pole/single-throw (SPST) contact configuration and is available in normally open (NO) and normally closed (NC) contact styles. The contact ratings are three amperes at a 24 VDC load and five amperes at a 120 VAC load. The maximum operating temperature range is -40°C to +82°C. The D4CC-4002 can be mounted directly or with a variety of mounting accessories. It is UL Listed and CSA Certified.

The working principle of the D4CC-4002 snap action, limit switch is based on the mechanical actuation of a set of contacts. The metal contacts are positioned in a frame made of either plastic or metal. When the frame is moved or pressed, the contacts are pushed together or separated to activate the switch. The contacts must be made of a non-magnetic material and are spring-loaded, so they will return to the "off" position when released.

The D4CC-4002 snap action, limit switch has an integrated gasket that provides IP68 ingress protection, which can protect the switch from dust, water and other hazardous materials, making it an ideal choice for applications in hazardous areas. Its double-brake system ensures reliable switching performance in high-vibration environments and the tail cover design provides a high degree of operator safety. The D4CC-4002 is also equipped with a simple and secure terminal block and electrical connection.

The D4CC-4002 snap action, limit switch is a reliable and robust switch designed for a variety of industrial applications. It is designed to provide reliable and accurate switching performance in harsh environments and hazardous areas, making it the perfect choice for applications that demand quality, performance and reliability.
