Feature Mercury switches are packaged in glass Hate It or metal shell casing mercury moves to implement the switch -off , thus mercury switches compared to mechanical switches, there are many features : 1. It can be used in harsh environmental conditions. As the mercury switch is sealed inside and outside the mercury is isolated, so it can be used in oil , steam, dust and corrosive gas environments. 2. Small -off force required. Mercury is the only metal can remain liquid at room temperature , the surface tension and gravity are large , with a little force the mercury switch is tilted , the mercury can be moved to realize the switch off . 3. Good conductivity of mercury, the mercury switch contact resistance between the electrodes is generally less than 100m. 4. Mercury switch allows current through the electrodes depends on the material, tungsten electrode maximum allowable current 10A, and the general alloy wire is generally the maximum allowable current is 1A. 5. Because mercury switch -off is determined by the gravity of mercury, so it can be a long-term reliable operation. 6. Contact with the contact electrode is a liquid, without any noise. 7. Because the mercury may flow, as long as the acceleration of the set value or more, the mercury switch can be on or off, which can be used as a vibration sensor. 8. Small size, diversity, and is fully sealed devices.
