The 402EN124-B snap action, limit switches are widely used in a variety of applications, including machinery and automation, safety and security, electronics, and many more. This type of switch, also known as a "rocker-arm" switch, has two contact configurations (normally closed and normally open) and an adjustable lever that allows the switch to be actuated either upon closure or upon opening. The lever can be set so that the switch is actuated upon the slightest change in pressure, force, or position. This makes the 402EN124-B suitable for applications requiring an instrumented, low-force actuation.

The 402EN124-B is designed for use in two-wire control circuits (SPST) and is commonly used for limit-switch applications. The contacts are spring-loaded and the switch will remain in a normally open or normally closed position until it is actuated by the user. The contacts will then open or close, depending on the switch\'s configuration, automatically resetting to their initial position when the actuating force is removed. This allows the user to toggle between on and off states with a single contact.

The construction of the 402EN124-B is designed to be able to withstand heavy use and provide a long service life. The switch is built with durable metal contact parts that are corrosion-resistant and are able to endure high levels of temperature. The switch also features electrical insulation and resistive shields to prevent current from flowing from the contacts to the user. Additionally, the switch is rated for both AC and DC applications.

When it comes to mechanical operation, the 402EN124-B is designed for relatively effortless actuation. The rocking arm can be adjusted so that the switch activates when the arm is moved a specific distance, typically ranging from a fraction of a millimeter up to a few centimeters. The amount of force required to actuate the switch will vary based on the type of application, as well as the lever settings. The 402EN124-B has a maximum actuator force rating of 1.2N.

The 402EN124-B can be used in a multitude of applications. Common usage includes the operation of gas, water, and electrical valves, the activation of alarm systems, and the controlling of light switches. Additionally, the switch is often used in robotics and automation, as well as on conveyor systems and medical equipment.

The 402EN124-B snap action, limit switch is a reliable and durable piece of equipment that can provide long-lasting service in a variety of applications. Its adjustable, low-force actuation lever allows for precise control and provides for more accurate triggering of events, making it a great choice for any application requiring reliable switching and control.
