Application: Mainly used for motor electric heating, bottles, cabinets, coffee makers, electric irons, dryers, air conditioning units, heaters, electronic cookers, and motor cleaners. Normally Closed (NC): When the temperature control switch is in the operating state (circuit connected), it trips (circuit disconnects) and stops working once the temperature exceeds the set threshold — ideal for applications like electric kettles. Specification: Name: Temperature Control Switch Action Temperature: 40°C Action Type: NC (Normally Closed) Rated Voltage/Current: 250V / 10A Pin Type: Bent-Pin Pin Width: 6.3 mm (0.25 inch) Contact Life: More than 50,000 cycles Electrical Strength: AC 50 Hz, 2000 V/min — no breakdown or arcing Quantity: 4 pcs Package Content: 4 pcs of 10A, 40°C, bent-pin, retaining-ring-type, Normally Closed temperature control switches. Other accessories are not included. Note: - Please allow for a 0.5–1 cm measurement tolerance due to manual measurement. - Due to lighting and screen differences, the actual item color may vary slightly from images. Notice: 1. Do not deform or crush the switch housing during installation. 2. This product is designed for contact temperature sensing only — not suitable for ambient air temperature sensing. 3. Secure mounting options include cable ties, copper wire, iron wire, mounting brackets, thermal conductive silicone, or 704 silicone rubber. 4. For accurate temperature sensing, ensure the switch is tightly attached to the surface of the equipment being controlled.
