When temperature rises to the rated threshold, the disc snaps open the circuit, cutting power and protecting your equipment from overheating. When the temperature falls back below the reset point, the disc snaps back and restores the circuit automatically — no manual reset required for most models.\u003c\/p\u003e\n\n\u003ch3\u003eCommon Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eElectric motors and transformers\u003c\/li\u003e\n  \u003cli\u003eHousehold heating appliances (hair dryers, irons, heaters)\u003c\/li\u003e\n  \u003cli\u003eBattery packs and charging equipment\u003c\/li\u003e\n  \u003cli\u003eCoffee makers, water heaters, and kitchen appliances\u003c\/li\u003e\n  \u003cli\u003eLED lighting assemblies\u003c\/li\u003e\n  \u003cli\u003eDIY electronics and prototyping projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eRelated Products You May Like\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/air-compressor-pressure-gauge-0-10-0-12-0-25-bar-hydraulic-diy\"\u003eAir Compressor Pressure Gauge 0-10\/0-12\/0-25 Bar | DIY Tool\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/electromagnetic-induction-tester-coil-motherboard-fault-detector\"\u003eElectromagnetic Induction Tester – Coil \u0026amp; Circuit Fault Detector\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/www.osha.gov\/hand-power-tools\" target=\"_blank\" rel=\"noopener\"\u003eOSHA guidance on hand and power tools\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What does \"normally closed\" mean for the KSD9700 bimetal disc temperature switch?\u003c\/h4\u003e\n\u003cp\u003eA: A normally closed (N\/C) switch means the circuit is \u003cstrong\u003eclosed (conducting electricity) at room temperature\u003c\/strong\u003e.
