Rotary switches are capable of carrying high currents and feature robust and modular construction. They can provide electrical isolation between the switch and the receiver, improving safety and reducing wear and tear of the device and related components. The 42HG36-12-1-03S is a type of rotary switch, and this article examines its application field and working principle.

Application Fields

The 42HG36-12-1-03S device is an off-the-shelf, rotary switch commonly used in industrial applications. Its configuration is ideal for use in switching power circuits, such as those used for controlling motors, fans, and pumps, as well as in temperature sensing or agricultural equipment control. It is a great solution for regulating voltage and current in-line circuits. The 42HG36-12-1-03S is an economical option for many applications owing to its low cost and reliable operation.

It is also well-suited for applications that require fast switching capabilities, like audio equipment, PLCs, and networking, as it has fast reaction time—it can change between different positions quickly, making it ideal for applications that require fast instruction processing.

These switches are primarily used in industrial machinery, automation systems, and computer systems. They are also used in AC circuits, to monitor line and load power, and to control signal flow. In addition, they can be used with DC applications like battery-powered systems, relays, and timers, or in data and communications systems.

Working Principle

The switches use a spring-loaded mechanism which helps keep the contacts in the on position when the switch is in its off position. When the switch is turned on, a small contact at the end of the spring moves into a new position and makes contact with the field wire. The current then flows from the field wire, through the switch, and then out to the receiver. This interaction between contact and field wire, controlled by the user\'s manual operation, is what makes the switch useful in industrial applications.

The 42HG36-12-1-03S rotary switch also features three poles and is rated for 3A at 125 VAC. The poles are arranged in an integrated pattern and are colour coded for easy identification of their respective positions. The poles are also marked to indicate their function, making it easy to set up the switch. The device is made from durable material and is able to withstand high levels of vibration and temperature.

Conclusion

The 42HG36-12-1-03S rotary switch is a great choice for industrial applications that require reliable high-load switching. It is relatively inexpensive, easy to use, and built to last. Its fast switching capabilities make it well-suited for applications that require fast instruction processing. By understanding their application field and working principle, engineers can make an informed decision on whether this switch is the right choice for their needs.
