A BFL1-BW1 switch is a member of a category of electrical components known as "snap action limit switches". These switches are designed to detect the presence or absence of an object, usually to then activate corresponding electrical signals which are then interpreted.The BFL1-BW1 was developed by Busch-Jaeger and released in the year 2018. It is a single-pole single-throw (SPST) momentary contact switch that is actuated either mechanically or electromechanically. This switch has a contact rating of 4A125VAC, making it suitable for many household, commercial, and industrial applications.The BFL1-BW1 has a broad range of application fields, such as lighting and low-voltage control, door and gate control, and industrial motor stops. For example, in a residential setting, the switch might be used to operate a porch light, while in an industrial context, it could be used to control a conveyor belt.The BFL1-BW1 switch works by utilizing an actuator to make and break contact between two terminals. This is made possible by the switch’s internal snap-action mechanism, which causes the contacts to open and close quickly and precisely. The internal mechanism utilizes a combination of a twitch and latching mechanism to ensure reliable, repeatable performance across many cycles. The twitch mechanism is the key to the switch’s ability to quickly open and close. It is comprised of an actuator plunger that is powered by a coiled tension spring. This actuator then moves an internal pinion gear that is mounted on a spindle, causing the spindle to rotate and forcing the contacts apart. The latching mechanism provides the switch with the necessary mechanical memory to reset itself and reconnect the contacts when the actuator is released. This mechanism is composed of two parts. The first is a retainer that holds the spindle in place when the actuator is released and pulls it back when the actuator is actuated again. The second part is a cam that lifts the contacts into the open position when the actuator is operated, and allows them to reconnect when the actuator is released.These two components, the twitch and latching mechanism, combine to create the reliable, repeatable performance and rapid responses that are necessary for industrial applications, such as controlling a conveyor belt.The BFL1-BW1 switch is available in a variety of body styles and materials, including plastic and metal. This makes the switch well-suited for many different applications, both indoor and outdoor. Additionally, the switch is designed to stand up to harsh weather and aggressive environments, making it suitable for demanding applications.Overall, the BFL1-BW1 from Busch-Jaeger is an ideal choice for many different situations. Its wide range of applications, combined with its ability to perform reliably in harsh conditions, makes it the go-to switch for any situation that requires a snap-action limit switch.
