CBH-S2 series dedicated to open transition critical power occasions higher requirements, are widely used in airports, hotels, hospitals and other communications, low voltage double power supply switching, using self-developed high performance electromagnetic coil by long-term use of proven as the switching mechanism, make each rated capacity automatic switch with fast switching capability fast conversion speed and stable. The main contact of excellent switching with load capacity, whether the load is electric or electronic converter for ROONSH, is an easy job to do things to convert any load, it is the real electromagnetic coil operation, mechanical interlocking type double throw switch.
