Snap action, limit switches are integral components in a wide range of motion control and automation applications that require constant monitoring of physical and/or dimensional parameters. The D4B-6A71N is a single-pole double-throw (SPDT) subminiature snap-action hermetically sealed flatted limit switch. It is an important electromechanical component usually used in motion control, automation, robotics, and other industrial operations requiring a reliable and robust switch for efficient operation.

• Application Field

The D4B-6A71N is suitable for a wide range of industrial and commercial applications, such as air-conditioning equipment, household appliances, electronic games, and vending machines. It is also well-suited for outdoor use in both wet and dry environments. It is generally used to control machinery movement and detect the presence of physical objects such as spoilage detectors. This type of switch is also used in liquid level controllers and door openers, as well as in computer-controlled systems that require precise activation and deactivation of solenoid valves.

• Working Principle

The D4B-6A71N is a hermetically sealed flatted limit switch with a single-pole double-throw (SPDT) snap-action design. The SPDT action allows the user to switch between two poles or states with a single motion. It also allows for constant monitoring of physical or dimensional parameters, as well as the re-positioning of a mechanical object or system.

The switch contains a plunger, an actuator and a cam. As the plunger is pushed, the actuator activates and the cam rotates to a certain angle, thus closing the contacts. The flatted switch design ensures contact durability and stability. Furthermore, its robust contact structure ensures consistently reliable performance in various environmental settings.

The switch features a wide operating temperature range, allowing it to be used in a variety of applications. The hermetically sealed design ensures a high level of protection against dirt, dust, and moisture. The metal enclosure also ensures superior switching performance in harsh environments.

The D4B-6A71N offers a reliable and cost-effective switching solution for numerous applications. Its highly precise mechanical design, coupled with its reliable operation, makes it ideal for applications requiring a robust switch with precise performance.
