Mercury is better, the conductivity of the mercury switch contact resistance between the electrodes is less than 100 m Ω commonly. (4) mercury switch allows current depends on the electrode materials, tungsten electrode for the maximum allowable current 10. A, the general wire normally maximum allowable current 1 a. (5) due to gravity to determine mercury switch on and off by mercury, so it can work reliably for a long time.
