ADPFC2W04AW

Snap Action, Limit Switches

ADPFC2W04AW is a snap action, limit switch from the Alco brand. It is a highly reliable and adjustable limit switch with various types of actuators and a wide selection of mounting holes for easy installation. The snap action, limit switch is designed to detect the end positions of a moving actuating rod and turn on/off a normally open circuit. It is used in many applications from medical equipment, robotics, and home appliances, to industrial safety and security systems.

Application Field

The ADPFC2W04AW snap action, limit switch can be used in many on/off/guard control applications. It is primarily used in robotics and home appliances to detect the end positions of a moving actuating rod. In this application, the switch will enable and disable the equipment, like when turning on a refrigerator or opening a window. The switch is also used in industrial safety control systems to shut down hazardous machinery in the event of an emergency, such as a fire or power surge.

The ADPFC2W04AW is also widely used in medical equipment, such as patient lift beds, x-ray machines and MRI scanners. Here, the limit switch will detect the correct positions for the operation of the machine, such as when a bed needs to be shifted to a certain angle or when an MRI scan should start. In such applications, the reliability and durability of the switch are of paramount importance, since the safety of the patient is at stake.

Working Principle

The mechanism of a snap action, limit switch consists of a contact and an actuator. As the actuator moves along its designated path, the contact is mechanically pushed into contact with a triggering element, completing the circuit. When the circuit is completed, the switch is activated/opened, triggering a response such as turning on/off a machine or changing its position. When the actuator retracts, the contact loses contact and the switch is disengaged/closed, eliminating the mechanical response of the test.

The ADPFC2W04AW snap action, limit switch offers the benefit of adjustable activation points. The point at which the contact is engaged can be adjusted by adjusting the position of the actuator. This allows the switch to be tailored to the specific needs of the application. For example, if a machine needs to begin operating at a certain point, the switch can be adjusted so that the contact is triggered at that point. This makes installation and programming of the switch easier and more efficient.

The ADPFC2W04AW snap action, limit switch offers several advantages. Its adjustable activation points make it more versatile than traditional limit switches. Its highly reliable design ensures a long service life and excellent electrical contact. It is also designed to protect its contact from dust, dirt, and other contaminants, ensuring the switch will remain functional for a long time. Finally, its wide selection of mounting holes makes installation quick and easy.
