Mechanical components are components with primarily moving parts, like the fan in a computer, or gears in an industrial machine. Electronic components are ones primarily unmoving, but with complex computer parts, like the motherboard of the computer, or the logic board in the industrial machine.
A computer is often referred to as electronic and mechanical equipment due to its combination of hardware and software components. The hardware includes electronic parts like the CPU, memory, and storage devices, while mechanical elements may involve components such as fans and drives. Together, these elements work to process, store, and manage data, enabling the execution of various tasks and applications.
The mechanical parts of a computer are included in the definition of the computer hardware. The mechanical parts are those working parts of the computer. It does not include the case, frame, and electronic components. That leaves the components involved in mechanical activity. The parts that move. That includes the switches, buttons, relays, cooling fans, hard disk drives and optical drives that spin and have read/write heads that can move back and forth across the disk surface. It also includes printers, scanners, speakers and headphones or their internal vibrating parts.

In an electronic switch there are no mechanical/moving parts - the switching action is achieved entirely within the electronic components. Electronic relays are generally a mechanical switch controlled by electronics.
Computer is not an Mechanical Machine, It is an Electronic Machine that works because of Movement of Electrons in controlled manner within Millions of Electronic Components (Resistors, Capacitors, Transistors, Diodes etc.).
The purpose of the electronic computer was to make conversion of raw data into useful information easier. Before the electronic computer, people used mechanical computers like the Abacus.
The electronic computer was not invented in 1641, there was no electronics in 1641. The electronic computer was invented in the 1940s. Charles Babbage did invent the programmable digital computer, the Analytical Engine, but it was mechanical not electronic.
There are different kinds of sensors and guages which measure pressure. The first ones were mechanical. The next generation were a combination of mechanical and electrical parts, and now, some pressure detecting systems have no moving parts, and are totally electronic.
