Import Bimetal Temperature Switch Ksd301 10a 250v — Buy in Bulk from Supplier in China

The KSD301 series bimetal temperature switch from Dongguan Yaxun Electronic Hardware Products Co., Ltd. is a snap-action thermostat rated for AC 250V at 10A resistive load, designed for precise thermal control in household and commercial appliances. The switch operates within a 0 to 300 °C range, with temperature accuracy options of ±2 °C, ±3 °C, ±5 °C or ±10 °C, allowing customisation for specific application needs. A bimetal disc inside the switch provides the thermal activation mechanism, ensuring rapid and reliable response to temperature changes.

Mechanical specifications include a life expectancy of 100,000 cycles, with electrical strength tested at AC 50Hz 1800V for 1 minute without flicker or breakdown. Contact resistance is maintained at ≤50 mΩ, while insulation resistance meets or exceeds 100 MΩ, ensuring safe and stable operation. The switch is available in normally closed or normally open configurations, with terminal options including plug terminals 250# or 187#, both compatible with 0.5 mm or 0.8 mm wire thickness.

This thermostat is widely used in appliances such as sterilizers, dishwashers, dryers and electric kettles, where temperature regulation is critical for safety and performance. The compact, lightweight design makes it suitable for integration into space-constrained assemblies, while its high reliability and long life reduce maintenance requirements. Buyers should specify the operating temperature range, accuracy and terminal configuration to match their application.

Dongguan Yaxun Electronic Hardware Products Co., Ltd. is based in Tutang Industrial Zone, Changping, Dongguan, Guangdong Province, a hub for electronic hardware manufacturing. The company holds a harbor trust tier, indicating a verified business presence, though its response rate on the platform is currently unrecorded. Its product range includes thermal control components, with the KSD301 series thermostat as a flagship offering for appliance manufacturers.

The supplier’s profile highlights certifications such as CQC, VDE, UL and CUL for the KSD301 series, confirming compliance with international safety and performance standards. However, the profile does not disclose production capacity, annual output or company history, so buyers should request these details directly. The focus on thermal switches suggests a specialization in temperature control solutions rather than a broad electronic catalog.
