A Snap Action, Limit Switch is an electromechanical device used for sensing in a wide range of applications, such as the automation and motion control of systems and machines, Process Control and Plant Automation. They are designed to act as a safety mechanism by automatically indicating the limit of a machine’s movement or to initiate an automatic stop of a process. Snap Action, Limit Switches employ a mechanism that causes a distinct, finite, and repeatable action when a certain predetermined limit is reached. This action triggers a response, most often an electrical output, that is interpreted by a process controller.The BFL1-AW1-S Snap Action, Limit Switch is designed to detect and cut off an over-representative electric field or electromagnetic wave, which can have harmful effects on the working and performance of a customer’s machine. This particular switch utilizes an insulated housing construction and contains an actuating plunger, an inner contact, and a disengaging cam. Additionally, it is built with a compact design for ease of installation and incorporates an adjustable mechanism with short actuating travel.When current passes through the inner coil of the BFL1-AW1-S, the plunger depresses the lever within the mechanism, activating the mechanism to initiate a response. This response causes the contact arm to activate and pulls the contact into the conical surface of the lever, thus connecting the switch’s electrical components. The contact remains in this position until the plunger is released, which is done by turning the switch off. When this happens, force is no longer applied to the contact arm, the contact is released, and the switch is then returned to its original position by a predetermined spring force.In the case of the BFL1-AW1-S, the mechanism has been designed to cut off current flow to protect against electromagnetic interference when an over-representative electric field or wave is detected. This mechanism is made up of a cam and a disengagement contact, which is separated by a predetermined compression gap. When the plunger is activated and force is applied to the contact arm, the plunger will lower until it hits the cam and the disengagement contact snaps out, cutting off contact between the switch’s electrical components and breaking the electrical circuit.The BFL1-AW1-S Snap Action Limit Switch is a highly efficient and reliable device designed to deliver excellent performance in a wide range of applications. With its compact design and adjustable features, it is easy to install, maintain, and troubleshoot. As such, it is an ideal choice for a wide range of industrial and commercial applications, such as process control, plant automation, and safety mechanism applications.
