Description:
A mercury switch is a type of electrical switch that operates based on the movement of a small amount of mercury metal inside a sealed glass bulb. The switch consists of two electrical contacts located at different positions within the bulb. When the switch is tilted or moved, gravity causes the mercury to flow and make contact with the electrical contacts, completing an electrical circuit. Mercury switches are commonly used in applications that require tilt or motion sensing, such as thermostats, level indicators, and tilt alarms. They have been widely used in the past due to their simplicity and reliability. However, their usage has declined in recent years due to environmental concerns related to the toxicity of mercury. Mercury is a hazardous substance, and the improper disposal or breakage of mercury switches can lead to pollution and health risks. As a result, alternative technologies, such as solid-state accelerometers and optical sensors, have become more prevalent for motion and tilt sensing applications.
