Toggle Switches

Toggle switches are versatile, reliable and commonly used in both commercial and residential applications. One type of toggle switch is the B12LH/328. This is a single-pole, double-throw toggle switch, designed to control two independent circuits. It can be used to open or close a circuit, or disconnect one circuit while connecting another.

Application Field

The B12LH/328 toggle switch is most commonly used in automotive and marine applications. It can be used to control a variety of devices, including lights, air conditioning, windshield wipers, and many more. Additionally, it can also be used in industrial applications such as machinery control, motor starting, and power switching. The toggle switch is capable of being used in a wide range of temperatures from -40C to +85C.

Working Principle

The B12LH/328 toggle switch is a single-pole, double-throw switch, meaning it can be used to control two independent circuits. It has three terminals. The first terminal is connected to the power source. The second terminal is connected to the load, while the third terminal is connected to the switching contact. When the switch is in the closed position, power is supplied to the load by completing the circuit between the power source and the load. When the toggle switch is in the open position, power is disconnected from the load and the circuit is broken.

The switch is composed of a toggle lever, a base, and a terminal block. The base of the switch serves several important functions. It provides a means of attaching the switch to the application, and it serves as a means of limiting the movement of the toggle lever. The terminal block of the switch holds the electrical terminals in place and is used to connect the wires to the switch. The toggle lever is used to open and close the switch, as well as to provide a visual indication of the switch\'s position.

The toggle switch can be actuated to both the open and closed positions in a straightforward manner. When the lever is moved to the desired position, the switch contacts open or close as necessary, thereby controlling the power supplied to the load. It is also possible to use intermediate positions in certain applications.

Advantages

The toggle switch has several advantages over other types of switches. It is easy to install, requires little maintenance, and is highly reliable. Its mechanical construction means that it is capable of withstanding high levels of shock and vibration, making it suitable for use in harsh environments. It is also very economical and can be used for a variety of applications.

Conclusion

The B12LH/328 toggle switch is a highly reliable, versatile switch. It is easy to install and requires little maintenance. It is capable of withstanding high levels of shock and vibration and is suitable for use across a range of applications. Along with its affordability, this makes the B12LH/328 the optimal toggle switch for many automotive and marine applications.
