rosenberger electrical components Germany rosenberger model rosenberger price

rosenberger 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 the air is evacuated from the tube, it is filled with various gases and sealed. They are suitable for environments with dust, oil, water vapor, corrosive gases, and can also be used as explosion-proof switches in places 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 position of the mercury immediately
