"E" could be damaged due to inrush current if "C" is large since "C" is effectively a short circuit when the switch is initially closed.
If "E" has a built in fuse, then it's fuse might eventually blow due with repeated switch closures, again due to the high inrush current if "C" is large.
Also, if the "K" switch contacts are underrated the contacts might "eventually" weld shut due to inrush current.
Sometimes a small value series resistor is placed between "E" and "K" to limit the inrush current.
