The KDHC40/3 is an adjustable 3position rotary changeover cam switch designed for control panels and equipment that require a selectable, isolated circuit path. With a 690V AC rating and a 40A current capacity, this model provides a compact and reliable means to switch between circuits using a single actuator. Key benefits Threeposition rotary action enables simple, reliable circuit selection within a single device. Adjustable cam allows tailoring switching points to match system timing or sequencing needs. Changeover functionality supports safe isolation and controlled power routing between circuits. Rated for up to 690V and 40A, making it suitable for mid to voltage control applications. Reduces wiring complexity by consolidating multiple switching functions into one compact switch. Key attributes Model: KDHC40/3 Type: Adjustable 3position rotary changeover cam switch Voltage rating: 690V Current rating: 40A Number of positions: 3 Operation: Rotary cam switch; adjustable Material: not specified in listing Size: not specified in listing Mounting: not specified in listing Applications and use cases Control panels in industrial machinery: use the 3position switch to select between multiple control circuits or modes without adding separate switches. Power source changeover with isolation: provide a safe, manual changeover between two power feeds, with an explicit third position for off or neutral as defined by the system. Motor or drive circuit selection in conveyors or processing lines: route power to different motors or drives from a single control point, with clear, repeatable cambased switching. Notes Ensure compatibility with your system's wiring practices and local electrical codes. Installation should be performed by qualified personnel following the appropriate manuals and safety standards.
