The Servo will not move if there is no force applied to it on power-down.
We are using a servo to hold a brake mechanism for our winch. When power off occurs, the spring tension will rotate the servo to a non stressed position.
For the purposes of activating a switch, the servo will not be "loaded' and therefore work for you.
