 Summary:

The interior part: fully sealed high temperature contact switches whose maximum allowable current is 5A/AC 220V. Since the contact is suffered special treatment, it can be used in high temperature environment for a long time without failure from oxidization or pollution.

The highest temperature of JDHK-2 series is 350 °C, while the long term working temperature is 250 °C. As for JDHK-3 series, The highest temperature is 650 °C, while the long term working temperature is 550 °C. It has filled the domestic blank of ultra-high temperature switch field. Every switch has roller, adjustable rod, pressure plunger to meet your different need. It’s widely used in electrical, chemical, petroleum, textiles, steel and other industries.
