Snap action, limit switches are designed to open and close an electrical circuit when a mechanical action, such as pressing a button or lever, is performed. The D4B-1111N is a snap action limiter switch designed for precision and reliability. This switch is available in three actuation styles: plunger, roller plunger and lever. The D4B-1111N meets UL, CSA and EN60947-5 standards and has a unique combination of features including durability, repeatability and flexibility.

The main application field of the D4B-1111N is as an actuator in industrial automation, robotics and instrumentation. In these applications, it is used to detect presence, position and movement. It is suitable for detecting a wide variety of objects including paper and sheet metal, small parts, batches and packages. The switch can also be used in food and beverage, medical and laboratory automation, printing and automotive systems.

The working principle of the D4B-1111N is based on its contact system. When the actuator is released, two electrical contacts move in opposite directions and make contact. At this stage, the circuit is closed, and a small amount of electricity flows through it. When the actuator is depressed or moved, the contacts move again, breaking the circuit and stopping the current flow. The electrical contacts remain in contact until the actuator is released again.

The D4B-1111N offers advantages such as durability, repeatability and flexibility. It is designed to withstand a wide range of environmental conditions, including vibration and shock, as well as temperatures ranging from -40°C to +125°C. The repeatability of the switch ensures that it will always provide the same response whenever it is actuated. The switch can also be used in a variety of applications and positions and can be easily adapted to fit different mechanical designs.

The D4B-1111N is also designed for easy installation and maintenance. Its compact size makes it easy to mount and the screws are not visible from the outside. The switch’s enclosure is designed to protect against water and dust. The electrical contacts are designed to maintain reliability even after millions of actuations. To prolong the life and performance of the switch, it should be lubricated with the manufacturer-recommended lubricant.

In conclusion, the D4B-1111N is a snap action, limit switch that is designed for precision and reliability. It is suitable for detecting presence, position and movement of a wide variety of objects in industrial automation, robotics and instrumentation. It is suitable for use in a wide range of environmental conditions and offers advantages such as durability, repeatability, flexibility and easy installation and maintenance.
