An Electro-mechanical switch is a type of relay or contactor that opens and closes with an electromagent. Power is applied to the coil or magnet which opens or closes mechanical contact points pre-wired in a configuration suited best for the application. These can be SPST, SPDT, DPDT
Usually in the case of a relay or contactor, the control voltage is a lower voltage AC or in a lot of situations can be DC. Essentially, you are using a small current to switch on/off a larger current, that would be less than optimal, convenient, and in most cases safe otherwise
Imagine you have a 20amp load or higher that you want to turn on or off. You could find a switch to throw on and off or a bus to pull out, but they're not really set up for automation. With a Relay/Contactor of the appropriate amperage rating you could feasibly turn this load on or off reliably, safely and automatically using a much lower current from a number of different sources such as 5VAC, 24VAC, 24VDC, or 120VAC from a switch, sensor, Programmable Logic Controller PLC, or a computer.

Definition for electromechanical design?
A device or system that is designed to be electrically actuated, like a device actuated by a solenoid, is an electromechanical design. Electromechanical engineers create this type of design.
What is the explanation for the types of Switching systems?
There are three type of switching system such as circuit switching ,packet switching , massage switching.

Which is used to convert DC to ac?
A power switching circuit called an inverter. You could also use an electromechanical motor-generator: DC motor turning an alternator.
Who invented the automatic switching system?
The first automatic switching system was introduced at the 1881 Paris Electrical Exposition, and a workable system had been patented by 1889.
When was the automatic switching system invented?

What are the advantages of electromechanical switches?
Some of the advantages of electromechanical relays include the facts that no heat sink is required, the contacts can be either AC or DC, and the initial cost is low. Some of the disadvantages include the contacts becoming worn, resulting in a limited lifespan, and that they don't perform that well when it comes to switching high inrush currents.
What are the Advantages of switching operating system?
Switching to a new operating system can have many benefits. It can be easier to store data or maneuver through information centers.
If switching time is 10microsecondsis this likely to be a major factor in the response of a client server system?
Switching factor
The telephone system uses packet-switching technology where as the Internet uses circuit-switching technology true or false?
False, the internet uses packet switching while telephones use circuit switching.
Is ms dos a multitasking operating system?
no...its single task switching system...
When was televesion invented?
In 1884 a university student in Germany patented the first electromechanical TV system. This system consisted of a scanning disk and spinning disk.
