Mercury switch 3/4/6MM universal 205 rolling position tilt one-way gravity Angle direct switch

Mercury switch is the use of mercury has good conductivity and fluidity of this feature to open and close the electrical circuit control. It is composed of glass tubes, mercury, fixed electrodes, leads, etc. After pumping out the air in the tube, it is sealed with various gases, which is suitable for places with dust, oil, water vapor, etc., and corrosive gases, and can also be used as explosion-proof switches in places with explosive gases. In view of the surface tension and specific gravity of the mercury in the tube is very large, and rich in fluidity, therefore, as long as the glass tube is slightly inclined, the position of the mercury will immediately change, and contact with the electrode in the way of surface contact, so that it can be used to divide and close the AC and DC large current. In addition, the characteristics of this switch are that the contact resistance is generally below 0.02 euro, the life can reach millions of times at the rated current, small size, high sensitivity, no mechanical noise, low price, etc., so it has always been used as an automatic control switch.
