DB1C-A1RB

Snap Action, Limit Switches

DB1C-A1RB snap action, limit switch is a spring field electromagnetic switch designed for high speed and repeatability applications. Snap action is a type of switching mechanism manufactured in two different types, normally open (NO) and normally closed (NC). It is commonly used in many safety applications, such as emergency stop switches, indicating lamps and machine interlock switches. The DB1C-A1RB snap action, limit switch is suitable for applications such as smoke detector switches, hand tool switches, waste water pump switches, automatic door switches and conveyor switches.

Working Principle

The working principle of snap action limit switch involves two main processes: energization and de-energization. The energization process occurs when an external circuit is connected, which activates the armature of the switch. Once the armature is energized, the switch latches. When the external circuit is turned off, the armature becomes de-energized, resulting in the switch returning to its original state.

When the external circuit is connected, an electric current is sent through a coil, which creates an electromagnetic field. This field attracts the armature of the switch and initiates the energization process. At the same time, a spring pushes the armature back to its original position. As the armature moves, a microswitch is opened and closed alternately.

Once the electricity flow has stopped, the armature is then automatically released by the switch’s return springs. This removes the pressure on the microswitch which then causes it to close. The switch will remain in this state until the external circuitry is connected again. This allows the snap action, limit switch to be repeatedly used without any wear or tear.

Advantages

The DB1C-A1RB snap action, limit switch has several advantages when compared to other types of switches. Firstly, the design of the switch means it requires very little force to operate. This means that the switch is easy to use, even for those with weakened hands or limited movement. Secondly, the switch is made of durable materials, so its performance and reliability won\'t be compromised in tough working environments.

The switch is also characterized by its fast switching speed, which is especially advantageous in applications that require quick responses. Additionally, the switch is extremely reliable and can be used in environments with hazardous temperatures and levels of humidity. Also, it is relatively easy to install and maintain, making it a cost-effective solution for many applications.

Conclusion

The DB1C-A1RB is a versatile snap action, limit switch that is suitable for a wide range of applications. Its fast switching speed and reliable operation make it suitable for use in safety applications and it is also highly cost effective. Its ease of installation and maintenance also make it a great choice for those who are looking for a reliable switch.
