A mercury switch is a regulating device that uses mercury to perform “automatic” functions. It is a very small capsule containing mercury and is incorporated into many electronic products. For example, a mercury tilt switch is used in some space heaters so that if a space heater accidentally falls over, it will shut off automatically. When the space heater falls the mercury in the mercury tilt switch is displaced and causes the machine to shut off.
