Toggle switches are electric switching devices that open and close circuits by moving one or more contacts along an axis. They are often used to control items in an electrical circuit, such as motors, lights, and other appliances. The B15AV toggle switch is a type of toggle switch that has a variety of applications, including industrial and commercial systems. Additionally, the switch’s working principle is unique and allows for more flexibility when controlling an electric circuit.

Applications

The B15AV is a toggle switch of the highest quality and is commonly used in industrial and commercial environments. With a 15A current rating and 250V/AC voltage rating, it is well-suited for a wide range of applications. Moreover, its UL 94 V1-rated polycarbonate housing provides protection against harsh environments, while its 2 poles and a single-touch lever actuation mechanism offer easy installation and operation. As such, the switch is commonly used in motor control centers, general purpose machinery, HVAC systems, and transformers.

Working Principle

The toggle switch works by moving an internal electrical contact between two positions. The “on” position connects the contact to the circuit’s live wire. The “off” position disconnects the contact from the circuit’s live wire. When the contact moves, a mechanical spring pushes the toggle switch back to its original position – either the “on” or “off” position. This process is referred to as “self-resettability” and prevents the toggle switch from being damaged by accidental or deliberate contact movements.

The switch requires a push of a finger or lever to move it from its original position. This movement triggers an internal mechanism, known as a “bimetallic strip”, which changes shape and closes the switch circuit. This closing of the switch circuit makes the switch in the “on” position with a electrical connection to the live wire. Releasing the finger or lever triggers the bimetallic strip to straighten back out and open the switch circuit, which returns the switch to its original “off” position.

Conclusion

The B15AV toggle switch is a reliable and durable electric switch suitable for a wide range of commercial and industrial electrical applications. Its UL 94 V1-rated polycarbonate housing and self-resettable mechanism provide superior protection and offer superior operating performance. Additionally, its working principle using bimetallic strips to close and open the switch circuit is the same on all toggle switches and provides an easy and reliable method for controlling an electric circuit.
