D4N-1225

The D4N-1225 is a type of snap action limit switch. It features an internal miniature snap action mechanism with a durable plastic body. It is a general-purpose switch that is suitable for many uses, such as motor control, automatic motor shut down, and fire alarm systems.

The working principle of a snap action limit switch is simple. It consists of two parts: a plunger and a contact. When the plunger is pressed by an external force, such as a push button or a lever, the plunger moves, and the contact closes, thereby creating a connection between the two parts. This action allows current to flow and activates the switch. When the external force is removed, the plunger resets itself, breaking the contact and breaking the circuit.

The D4N-1225 is commonly used in applications where a durable and reliable switch is needed. It is used in the fields of motor control, such as controlling motor start and stop, as well as used for fire alarm systems. It can also be used in applications that require safety switching monitoring, such as medical equipment, and control systems for home and building automation.

The D4N-1225 is designed for a range of operating temperatures, from -20°C to +85°C. It is also designed to operate smoothly and reliably in harsh environments, due to its IP65 rating, which means it is dust-proof and waterproof.

Overall, the D4N-1225 is an ideal limit switch for applications that require durability and reliability. Its simple and dependable working principle, along with its durable plastic body and waterproof rating, make this switch a great choice for a variety of applications.
