DOEPKESCHALTGER electrical components Germany DOEPKESCHALTGER model DOEPKESCHALTGER price

DOEPKESCHALTGER electrical components utilize the good conductivity and fluidity of mercury to control the opening and closing of electrical circuits. They consist of a glass tube, mercury, fixed electrodes, lead wires, etc. After evacuating the air from the tube, it is filled with various gases and sealed. It is suitable for environments with dust, oil, water vapor, and corrosive gases, and can also be used as an explosion-proof switch in environments with explosive gases. Given the high surface tension and specific gravity of the mercury inside the tube, as well as its fluidity, as long as the glass tube is slightly tilted, the mercury's
