How do infinite switches perform when subjected to their maximum load rating?

Infinite switches are designed to control the electrical flow to equipment, providing variable speed or intensity based on the user's adjustment. When these switches are operated at their maximum load rating, they may fail due to heat. This is because continuous operation at maximum capacity generates significant heat, which can lead to overheating. As the thermal energy builds up, it can exceed the material limits of the switch components, leading to degradation or failure.

Operating a switch at or near its maximum capacity increases the risk of thermal overload, which can cause physical damage, electrical arcing, or even complete failure of the switch. Hence, while a switch may function within its specifications temporarily, sustained maximum load can compromise its integrity over time, ultimately leading to a failure event. This highlights the importance of adhering to the manufacturer's specifications and employing switches within their recommended usage guidelines to ensure safety and longevity.
