boehm electrical components Germany boehm model boehm price

boehm 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 places with explosive gases. Given the high surface tension and specific gravity of the mercury inside the tube, along with its fluidity, the position of the mercury changes immediately with even a slight tilt of the glass tube, and by means of surface
