Not necessarily. If the arm contacted a spring (a cushioned hard-stop is a good idea anyway) that was able to push the arm off the switch after the switch cut power to the motor, you could reset everything. That's just an example.

This, however, is the most important part.

Before you fix something, it's worthwhile to make a concerted effort to figure out why it failed. Software could be the cause. Or lack of a flexible extension on the actuation lever. Or improper mounting of the switch.
