Snap Action, Limit Switches

BFR1-BL1 is a type of snap action, limit switch. This device is made of several components and has a simple working principle.

Components

The device has a housing, a plunger and a rotary blade, an actuating arm, a roller and a pivot lever, and a contact block assembly. The housing is usually made of metal and contains all the other components. The plunger is a metal rod that moves into the housing when triggered. The rotary blade is a spring-loaded arm that rotates in the housing and acts as a trigger. The actuating arm is a piece of metal which contacts the roller when the plunger is pushed into the housing. The roller is a wheel that is in contact with the lever, and is responsible for the actuation of the switch. The pivot lever is a piece of metal that contacts the contact block in order to complete or break the circuit.

Working Principle

When the plunger is pushed into the housing, it activates the rotary blade and causes the actuating arm to contact the roller. The roller then turns the pivot lever and the contact block is moved to its appropriate position. This movement of the contact block can either open or close the circuit, depending on its setting. When the plunger is released, the action of the spring moves the actuating arm back to its original position and the contact block is reset.

Uses

BFR1-BL1 are used in a variety of applications. They are used in various motion control applications, including door interlocks, control panels, and limit/emergency stops. They can also be used for machine control and indication, such as machine start/stop signals and safety functions. In addition, they can be used as part of security systems, such as electric locks and alarm systems. They are also used for a variety of industrial process control applications, such as monitoring the temperature, pressure, and flow of liquids and gases.

Advantages

The main advantage of this type of snap action, limit switch is its simplicity and durability. It is a low-cost option and can be used in a wide range of situations and environments. It is also low-maintenance as it does not have any moving components. The contact block is made of materials that are resistant to wear and tear and its actuation is reliable and consistent. Additionally, the switch is designed to be resistant to shock and vibration and can withstand a wide range of temperatures.

Conclusion

BFR1-BL1 is an excellent solution for a wide range of applications. It is a simple and reliable device with low cost and maintenance requirements. Its actuation is reliable and consistent and it is resistant to shock and vibration. It can be used in a wide range of situations and environments and is suitable for use in a variety of industrial and security applications.
