5pcs Mercury switch Tilt switch 3MM 5MM Tilt one-way gravity scroll switch
The mercury switch uses the characteristics of mercury to have good conductivity and fluidity to control the opening and closing of the electrical circuit.
It is composed of glass tube, mercury, fixed electrode, lead and so on.
After the air is drawn from the tube, it is filled with various gases to seal it. It is suitable for places with dust, oil, steam, etc. and corrosive gases, and can also be used as an explosion-proof
switch in places with explosive gases.
In view of the large surface tension and specific gravity of the mercury in the tube, and it is rich in fluidity, as long as the glass tube is slightly tilted, the position of the mercury will change
immediately, and contact with the electrode in a surface contact manner, so it can be used to separate and combine AC and DC. High Current.

Current: 0.3A
Working temperature: -40°C-300°C
