KSD9700 250V/5A NC 80℃ Temperature Control Switch

Snap-Action Bimetallic Thermal Disc: Utilizes a highly responsive bimetallic disc mechanism that rapidly trips to interrupt circuit power when ambient temperature reaches 80°C.

Normally Closed (NC) Contact Configuration: Features a default closed state that automatically snaps open at 80°C to cut off current and prevent overheating in sensitive electronics.

Compact Metal Casing Enclosure: Housed in a sealed, low-profile metallic casing that provides excellent thermal conductivity and mechanical protection.

Pre-Wired Insulated Lead Wires: Equipped with flexible, heat-resistant lead wire tails for hassle-free soldering or terminal connection into custom thermal protection harnesses.

Automatic Reset Functionality: Automatically resets and restores contact closure once ambient temperatures drop safely below the trip threshold.

Housing Material: High-thermal-conductivity metal casing with insulated flexible lead wires.

Technical Specifications:

Switch Type: Normally Closed (NC).

Trip Temperature: 80°C ( 5°C).

Electrical Rating: 250V AC / 5A.

Color: Silver Metallic Casing with Black Insulation Leads.

Usage Advice: Ensure thermal compound or tight physical clamping is applied against the target heating surface for optimal heat transfer and rapid thermal response.

Maintenance: Avoid crushing or bending the metallic sensor head, as physical deformation can shift the internal bimetallic actuation setpoint.

Essential Overheat Safety Switch: Position as a cost-effective, passive safety cut-off switch for electric motors, transformers, battery packs, power supplies, and household appliances.

Highlight Reliable Hardware Protection: Emphasize how this fail-safe snap-action switch protects high-cost power electronics from thermal runaway without requiring microcontrollers or software loops.

Recommended Cross-Sell Add-ons: Pair with 1M DS18b20 temperature probe, 3M DS18b20 temperature probe, PT100 Platinum Resister Temp Sensor Probe -20℃~450, and ESD antistatic mat 50x40CM PCB Welding Mat.
