It is a thermometer, and is used to show the temperature.
what do they use for the liquid in glass ball thermometer
Mercury conducts electricity. These switches are usually used in thermometers in air conditioners, etc. There is a coil that is temperature sensitive that causes the mercury to tilt. There are also two electric poles inside of the glass the mercury is contained in. If the glass it tilted in one direction, the liquid mercury encompasses both poles and completes the circuit. If the glass is tilted in the OTHER direction, the mercury moves away from the poles and opens the circuit.
A manometer is a device that is used to measure the pressure of a fluid. The U-shaped glass tube is partially filled with a liquid, usually mercury. The difference between the height of the mercury corresponds to the difference between the pressure of the fluid in the container and the atmospheric pressure.

Liquids expands on heating and contracts om cooling , when it expands it gives the reading

Thermometer. They contain Mercury which is a metal.

what do they use for the liquid in glass ball thermometer
Mercury does not wet glass due to one of it's most significant properties. Mercury will not cling to the glass that contains it.
Glass is a super cooled liquid .
The sensor is just the mercury, a liquid metal.
