The KSD9700 thermostatic switch utilizes a precision bimetal disc as its sensing and actuating element. In normal operation, the disc remains in a free state, keeping the internal snap-action contacts closed to maintain circuit continuity. When the ambient temperature rises to the calibrated trip point (80°C), the bimetal disc deflects, mechanically snapping the contacts open to break the electrical circuit, thereby protecting the connected equipment from overheating.
After the fault condition is removed and the temperature cools below the reset point (typically 10-20°C below the trip temperature), the bimetal disc returns to its original shape, automatically reclosing the contacts to restore power. This self-resetting, purely mechanical operation makes it a robust and maintenance-free solution for over-temperature protection without requiring external power or control logic.
