D4B-4171N-NPT Application Field and Working Principle

Snap Action, Limit Switches are widely used in the fields of industrial automation, security monitoring, data collection, home appliances, automotive industry, communication network, etc. As one of the most commonly used snap action switches, D4B-4171N-NPT is a full-seal switch with maximum insulation resistance of 100 mohms, contact material of AgNi-15 / AgCdO, working voltage of AC 160 V, DC 150 V and insulation voltage of AC 600V.

The snap action mechanism is primarily responsible for the rapid and precise switching operations, which makes it suitable for harsh industrial and automation environments. D4B-4171N-NPT has a wide operating temperature range from -40 C to +85 C and is resistant to shock and vibration up to 50 Hz. With its wide variety of features, D4B-4171N-NPT is ideal for a variety of applications, including industrial automation, home appliances, security monitoring, and data collection.

Let\'s take a closer look at the working principle of D4B-4171N-NPT Switch. The switch consists of a contact blade, a switch lever, and a housing mounted on the circuit board. When the switch is activated, a small current passes through the contact blades, which causes it to move and contact the circuit board. This causes a circuit to be completed and a signal to be sent to the external circuit. The movement of the switch blade is determined by a series of springs which are carefully calibrated to ensure a precise reaction. When the lever is released, the springs restore the switch blade to its original position and break the contact with the circuit board.

In addition to the snap action design, D4B-4171N-NPT has several other features. It is equipped with two grooves at its base which can be used to fix it securely to the circuit. The switch also features a dust and moisture protection mechanism, which helps to ensure that it performs reliably in any environment. The flexible leads also provide an easy installation and maintenance process.

Overall, D4B-4171N-NPT is an extremely reliable snap action switch. Its precise diagnostic and responsive action makes it suitable for a wide range of industrial, home and security applications. The robust construction ensures a long service life, while the dust and moistureproof construction ensures the safety and reliability of the switch in any environment. With a wide variety of features and a low cost, it is an excellent choice for any application.
