Temperature Switch KSD 9700
Product Details
Temperature Switch KSD 9700 is a temperature-sensitive switch that opens or closes electrical contacts depending on the predetermined temperature. This type of technical component is employed in many devices to give overheating protection, such as in motors, transformers, heating pads, and air conditioning.

How it Operates?
1-Typical operation:
In NC configuration, the switch will permit current flow until the ambient temperature rises to the trip point.
In NO configuration, the switch will remain open until the temperature rises and the switch is activated.
2-Activation:
When the set temperature is reached, the bimetal disc snaps into its changed state. In this case, NC opens and NO closes.
3-Reset:
Once the temperature falls below the reset temperature (typically 15-45 °C less than the trip temperature) the switch returns to its default state without needing to take any further action.
Feature of Temperature Switch KSD 9700
1-Auto-Reset: Closes again to its original state when temperature drops below threshold. This is the key feature.
2-Snap Action: Provides quick, positive opening/closing of contacts for dependable switching and less arcing.
3-Fixed Temperature: Each switch is calibrated to open at one temperature. This temperature is usually stamped or printed on the body, (e.g., "85°C", "120°C", "150°C").
