Mercury Levels Switch (ARD269)

The tilt switch is activated through a change within the position of the switch.

• Mercury switches provide extremely high surface tension.
• The empty bulb of this switch is filled with inert gas, so it avoids the oxidation of electrodes. So mercury switch provides an extremely long operating life.
• Less cost & simple to use.
• It is observable because its color is silvery shining.
• It is extremely strong because mercury does not fade away easily.
• Contacts in the switch stay hygienic even if an inside arc is formed, the surfaces of contact are changed on each operation, thus the contacts don’t exhaust.
• A small mercury drop has a low resistance, so these switches can carry useful amounts of current within a small size.
• The contacts of this switch are enclosed, thus corrosion of the contacts is not possible.
• Contacts stay clean, and even if an internal arc occurs, the contact surfaces renew on every operation, so they don’t wear out.
