Cam-driven rotary switch: a rotating cam switch designed for convenient and practical switching of the power supply path in motor control, and suitable as a replacement for the original switch. Two-position design: provides two selectable positions for straightforward power-supply switching in motor control applications. Replacement switch: enables simple and efficient switching between power sources, helping keep your motor-control system operating smoothly and reliably. High-current capability: supports high current capacity in a two-position configuration, delivering reliable performance across different electrical systems and allowing easy replacement of the rotary switch. Applications and use scenarios: - In motor control panels of machines or conveyors to switch between main power and a backup or test supply. - In robotics projects to select between battery power and external power. - In industrial drives for routine maintenance or testing that requires switching power paths without replacing the entire control wiring.
