This switch Using mercury switch as a electric contact, It's consisted of high strength aluminum alloy explosion-proof enclosure, With reliable work, Lightweight and durable, etc. Particularly suitable for general mechanical contactor switch which is not up to a bad situation. The Installation and principle of action for explosion-proof mercury switch is basically the same as general limit switches. It is more convenient for use.
Explosion-proof Limit mercury switch is suitable for mine and Oil chemical plant Such as with level of com bustible gas, or Dust, moisture and corrosive medium environment, as uesd in exercise mechanical limit, protection, signal, position detection control. Such as: The mine shaft hoisting, tank car parking, overwinding protection; The pusher, the position detection and control of the dumper Coal basket door switch signals and belt conveyor running deviation, strip break protection, etc.
