a contactor is generally looks like a small box connected to an electric circuit. it is what controls electricity flow to a motor. in the middle is normally a way to push in the contactor to manually check to see if either the motor works or if you have electricity.
As well as motors, contactors also have kW and Ampere ratings. Have a look on the name plate of your motor and you will see its maximum current draw (amps). Select a contactor with a current rating greater than this.
With a contactor we can control the power connection to the motor (power on/off). A typical AC contactor comes with 4 terminals aside (L1,L2,L3,A). 'A' has A1,A2 terminals which are of the magnetizing coil. By magnetizing & demagnetizing A1-A2 coil, power line connections to motor can either be made or broken. This is a simple DOL (Direct On Line) application. Further, reverse/forward circuits and star-delta circuits can be constructed based on the requirement. A contactor's role in whatever application is 'making or breaking' the contact. The coil supply can either be AC or DC.
let look from the different angle, mechanical engineering and ece has almost equal scope but mechanical have little higher because mechanical has wide variety of subjects and every skilled mechanical engineer has got statisfyed job.... now we look from ece,ece is the easy to learn and has good job outlook,every professsionaly skilled engineerhas good job aspect...
what do robots look like today?
Although in the movies they look like robots, they are NOT robots, they are bio-mechanical, meaning they are like cyborgs, like 20% mechanical. They most likely look robotic due to their armor.

Under a microscope, Velcro appears as a mechanical fastening system with tiny hooked loops on one side and a corresponding looped surface on the other side. The hooks and loops interlock when pressed together, providing a secure fastening mechanism.
hi in jersy one side look line and another side is purl, mostly we used for t shirt and interlock is both side ribbed, like single jersy line. and in rib one drop needle used

The contactor on the outdoor unit is probably stuck. Disconnect the power to the indoor unit, then disconnect the power to the outdoor unit and take a look at the contactor.
A mechanical thing on a track in the middle often designed to look like a rabbit.

A glitch is a problem with a system that may either mechanical or otherwise. It can often be difficult to troubleshoot.
Interlock fabric is a variation of rib knit construction. Similar to a Jersey knit except both front and back of the fabric look identical. Double knit construction makes this a thicker knit fabric. Interlock is the tightest weave, gives the smoothest surface and the finest hand. The fabric is extremely soft, firm and absorbent.
The dragon is mechanical, like all of Binary Bard's creations. (see the related image link below)
