Rocker switches are a type of switch that have been used by electronics designers and engineers in a variety of applications over the years. The B227J3ZQ2 rocker switch is a popular choice for many electronic designs. This article will cover the application field and working principle of this switch.

Application Field

The B227J3ZQ2 rocker switch is a single-pole, double-throw rocker switch designed for electrical power transfer applications. This switch is popularly used in a variety of markets including automotive, industrial, alarm systems, military and other low-voltage applications.

The switch is rated for 5A at 125VAC or 3A at 250VAC. This makes it suitable for use in many environments where higher power is a requirement. It is also UL certified to indicate its safety for use in electrical systems.

Working Principle

The B227J3ZQ2 rocker switch uses a rocking mechanism to switch electrical power from one terminal to another. When the switch is in the “on” position, power is transferred from the input terminal to the output terminal. When the switch is in the “off” position, no power is transferred.

When the switch is in the “on” position, the action of the switch causes the contacts of the switch to be pushed together, momentarily closing the circuit before being pulled apart again. This action of the switch physically isolates the incoming and outgoing terminals and prevents electrical power transfer.

The switch also features an LED indicator that can be used as a visual cue to alert users when the switch is turned on. This is a useful feature in applications where instant switching is necessary or to identify which switch is in a certain state in complex systems.

Conclusion

The B227J3ZQ2 rocker switch is a popular choice for many electronic designs as it provides reliable operation and an LED indicator for a visual signal. This switch can be used in a variety of applications including automotive, industrial, alarm systems and military applications due to its UL certification and higher power ratings.

Through its rocking action, the switch is able to isolate the input and output terminals, preventing electrical power transfer when the switch is in the “off” position. The LED indicator provides a visual signal when the switch is in the “on” position.
