Snap Action, Limit Switches: D4N-1262

Snap action switches, or limit switches, are electromechanical devices consisting of a pivoting, spring-loaded actuator and an electrical contact. Most often, the actuator is a button, plunger, or lever and the contact is a pair of electrical contacts that open or close a circuit. The actuator is typically operated by an external force of some kind, such as press-fit buttons, levers, or toggle switches. The D4N-1262 is a type of snap action, limit switch with a 1/2” (12-mm) diameter body and 1/4” (7.8-mm) diameter plunger. It is designed to provide accurate, repeatable switching action in applications that require a high degree of precision and reliability. The D4N-1262 is rated for a maximum ambient operating temperature of 105°C and a maximum electrical rating of 10A at 250V AC/DC, 1/2HP at 125/250V AC, or 1/3HP at 125V AC. The switch is available with either normally open (NO) or normally closed (NC) contacts, and can be operated manually or by an external force.The D4N-1262 is typically used in industrial and commercial applications that require reliable, repeatable switching in hazardous or difficult conditions. Typical applications include process control, motor speed control, safety circuits, and motor starter switching. The switch can also be used in home automation systems and HVAC applications.The D4N-1262’s operation is based on a spring-loaded, momentary contact mechanism similar to that of a conventional switch. When the plunger is operated by an external force, the mechanical action of the plunger causes the switch contacts to either open or close. When the force is removed, the force of the spring returns the switch to its original state. This design ensures that the circuit remains in the desired state regardless of external forces or mechanical vibrations.The D4N-1262 is also designed to be durable and reliable. The contact elements are made from stainless steel, which is resistant to corrosion and other forms of wear. The plunger is encased in a sealed housing to protect it from dirt and moisture. The switch also has small mechanical latches on the end of the plunger that lock the plunger into place, preventing it from being accidentally shifted.The D4N-1262 is a reliable, repeatable switch that is designed for use in applications that require a high degree of precision and reliability. Its durability and low maintenance requirements make it a popular choice for industrial and commercial applications. By utilizing a spring-loaded, momentary contact mechanism, the switch is capable of withstanding the forces of vibration and shocks. Its resistant contact material and sealed housing also ensure that the switch is reliable even in hazardous or difficult conditions.
