The mercury switch is switched on and off according to the movement of mercury enclosed in a glass or metal case, so the mercury switch has many features compared to mechanical switches.
① can be used under harsh environmental conditions. Because the mercury switch is sealed, the internal mercury is isolated from the outside world, so it can be used in environments with oil, steam, dust and corrosive gases.
② off the required external force. Mercury is the only metal that can remain liquid at room temperature. Its surface tension and specific gravity are large. As long as the external force makes the mercury switch tilt, the mercury can move and the switch can be switched on and off.
③ mercury conductivity is better, the contact resistance between the mercury switch electrode is generally less than 100mΩ.
④ mercury switch allows the current through the electrode material, Magpie electrode maximum allowable current 10A, while the general maximum allowable current alloy wire is generally 1A.
⑤ As the mercury switch on and off determined by the mercury gravity, so it can be long-term and reliable work.
⑥ electrode contact is liquid contact, without any noise.
⑦ As the mercury can flow as long as the acceleration reaches the set value above, the mercury switch can be on or off, which can be used as a vibration sensitive components.
⑧ small size, diverse forms, and all sealed devices.
