Description

Bimetal thermal switch ST01H is a not reset automatically thermal switch, which has great performance on low-temperature endurance test, high-temperature endurance test, drop test, moisture endurance test, and durability test.

 

Applications:

• Electric Motors and fans
• Transformers
• Coils
• Electric products

 

Supporting technology:

• Integrate the resources of the global supply chain, the bimetal-disc materials are imported from the world’s largest manufacturer USA EMS, and the case   stamping forming technology from the German supplier.
• The spring material comes from Japanese NGK.
• The case and contact are silver-plated, which greatly reduces the contact resistance.
• The core componentte bimetal- disc produced by automated molding equipment and sorted by tunnel oven separation equipment, with good consistency and stable performance.
