Pushbutton switches: PB-12331AVQ application field and working principle

Pushbutton switches are a type of electrical switching device with two or more terminals and are typically used for manual operation. Pushbutton switches are commonly used in applications such as industrial and residential lighting, alarms, fire alarm systems, security systems, industrial machinery, and lab automation. The PB-12331AVQ is a miniature pushbutton switch manufactured by Littelfuse.

PB-12331AVQ features

The PB-12331AVQ toggle switch offers a wide range of features, making it suitable for a variety of applications. The switch features a momentary Operate-Release (O-R) function and is rated for a maximum voltage and current of 120VAC and 5A, respectively. It has a silver-plated center tip contacts, a low profile design, and is UL/CSA approved for use in general purpose and Industrial control applications. The switch also has an off-mom operation indicating it can be used to switch an electrical circuit off temporarily or to toggle on or off.

PB-12331AVQ application fields

The PB-12331AVQ switch can be used in a variety of applications, including industrial and residential lighting, alarms, fire alarm systems, security systems, industrial machinery, and lab automation. Its low profile and silver-plated contacts make it particularly well-suited for applications where tight space requirements, low magnetic susceptibility, and high performance are desired. The switch can also be used to control and disconnect motors, pumps, and other industrial equipment.

PB-12331AVQ working principle

The PB-12331AVQ is a momentary switch that operates and releases with a single press. When the switch is pressed, the internal contacts are closed and the circuit is completed. When the pushbutton is released, the contacts return to their original position and the circuit is again opened. The switch is pre-conditioned and tested to ensure that the contacts open before current is applied to the circuit, minimizing the possibility of electrical arcing. The PB-12331AVQ also has a high contact life rating and is capable of up to 100,000 cycles.

Conclusion

The PB-12331AVQ pushbutton switch from Littelfuse is a low profile, silver-plated pushbutton switch that is suitable for use in a variety of applications, including industrial and residential lighting, alarms, fire alarm systems, security systems, industrial machinery, and lab automation. The switch is rated for up to 120VAC and 5A, which make it ideal for controlling and disconnecting motors, pumps, and other industrial equipment. It features an internal Operate-Release system and high contact life rating, making it reliable and capable of up to 100,000 cycles.
