Electrical contacts at the control switch in its easy to produce sparks

Electrical contacts at the control switch in its easy to produce sparks causing the switch contacts carbonization and corrosion, which can affect their life and poor reliability. Ordinary electrical electric transformer this defect, presents a non-contact electrical contacts design. By changing the traditional mechanical contact mcb circuit breaker structure, using non-contact switch fully electronic instrument in the work process can be eliminated to produce a spark, to extend the life of the instrument, the instrument switches to improve speed and reliability. Ordinary Electric transformer adapted after the test, the test results demonstrate the viability of this program. In addition to the general situation, but the program can also be used directly for explosive and other special occasions.
