Toggle switches have been the workhorse of electronics control since the beginning of the 20th century. Whether it’s a light switch in your home or a power switch in a power plant, toggle switches are everywhere. Although we haven’t seen many advances in technologies in recent years, one particular type of toggle switches called the 7403MDAV2BE is quickly gaining popularity in various applications. In this article, we’ll take a look at the application fields and working principle of the 7403MDAV2BE switch.

What are the Application Fields of the 7403MDAV2BE Switch?

The 7403MDAV2BE switch is a 2-pole, double throw (2PDT) toggle switch with two contacts per pole. It has a datasheet rating of 3A 115VAC, and 2A 24VDC, making it suitable for a wide range of applications. Common application fields include automotive, audio, marine, industrial welders, heavy machinery, and many more.

In automotive applications, it is used primarily as a safety switch and as an emergency-stop switch. In audio applications, it is used as a toggle switch to switch between different audio functions. In marine applications, it is used to switch between multiple electrical circuits, such as lights and power switches. In industrial welders, it is used to control the welding arc, as well as for other welding control functions. In heavy machinery, it is used to control features such as power, operations, speed and direction.

What is the Working Principle of the 7403MDAV2BE Switch?

The 7403MDAV2BE switch works on a simple principle. It uses a toggle lever to switch between two circuits. When the toggle is flipped, one of the contacts is closed and another one is opened, allowing the current to flow through one of the circuits. Flip it again and the circuit is switched, allowing the current to flow through the other circuit.

The switch is designed to be very reliable and is built with an internal gold contact system. This provides a low resistance, low heat, and low contact bouncing which makes it perfect for use in automotive, audio, marine, and industrial applications. The switch also features a push-to-test feature which allows users to test both contacts in a single action.

The switch also features a wide range of actuator sizes so that it can be used in both regular and extraordinary applications. The actuator length can range from 8.0mm to 20.2mm and the actuator width can range from 7.1mm to 11.0mm. This makes it suitable for both tight and wide spaces.

Conclusion

The 7403MDAV2BE toggle switch is a versatile and reliable switch that is suitable for a wide range of applications. It can be used in automotive, audio, marine, and industrial applications and its gold contact system provides low resistance, low heat, and low contact bouncing. The switch also features a wide range of actuator sizes which makes it perfect for both regular and extraordinary applications. It is quickly gaining popularity in various industries and is sure to remain a fixture in electronics control for a long time.
