It was first invented by Joseph Conrad Barrette who worked for GE in the 1950's. Unfortunately, he did not patent his idea and it was stolen by GE.
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
Santorio Santorio was the first inventor to put a numerical scale on the instrument. Galileo Galilei invented a rudimentary water thermometer in 1593 which, for the first time, allowed temperature variations to be measured. In 1714, Gabriel Fahrenheit invented the first mercury thermometer, the modern 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.
The mercury manometer was invented by Evangelista Torricelli in 1643. Torricelli was an Italian physicist and mathematician who discovered that the height of a column of mercury in a tube varied with atmospheric pressure, leading to the creation of the mercury manometer for measuring pressure.
The concept of air pressure was first discovered by Evangelista Torricelli, an Italian physicist and mathematician, in 1643. He invented the mercury barometer to measure atmospheric pressure, which led to the understanding of how air pressure behaves in different conditions.

In 1724 Gabriel Fahrenheit invented the first mercury thermometer.

The first modern thermometer, the mercury thermometer with a standardized scale, was invented by Daniel Gabriel Fahrenheit in 1714.
the earliest safe dimmer switch - used in the theater - was invented by Granville Woods in the 1890's.
The first light switch was invented by John Henry Holmes in 1884 I think. Not sure about any other switch. Hope this Helps!
In 1714, Gabriel Fahrenheit invented the first mercury thermometer.
The worlds first light switch was invented by Moe Goldberg in 1893.

A mercury switch is an electronic switch that opens or closes a circuit when the switch, or device it is attached to, tilts.
Torricelli invented a device for measuring air pressure called a mercury barometer. It consists of a glass tube filled with mercury placed in a dish of mercury. The height of the mercury in the tube changes with variations in atmospheric pressure.
It was Daniel Gabriel Fahrenheit.
