What Are Cam Switches?

Cam switches are usually used in low-voltage applications. Switching cams are constructed of abrasion-resistant conductive metal and are mounted on a shaft. The connections are opened or closed by the cams when the shaft rotates. Cam switches will power three-phase 480-volt motor circuits and 120-volt protection circuits at the same time, making them ideal for irrigation systems. A standard pivot irrigation system has 8 to 10 motors and is around one-fourth of a mile long. Each motor is often housed in a tower with a control panel.
