The KSD9700/BK05-BB1D is a bimetallic disc thermal switch housed in a metallic shell for optimal heat transfer and mechanical protection. Its operating principle relies on the differential expansion of two bonded metals, which causes a sudden snap-action to close the normally open electrical contacts once the calibrated temperature threshold of 115°C is reached. This action completes the circuit, enabling it to activate alarms, cut power, or trigger cooling systems.
Designed for direct series connection in a live circuit, this switch provides a cost-effective and maintenance-free solution for over-temperature protection. Its sealed metallic housing offers resistance to environmental contaminants and ensures long-term stability across a wide range of industrial and commercial applications where reliable thermal management is critical.
