After viewing the link provided by Gibson, I take that back! You could mount the switch in a frame mechanically anchored to the ground and then place a steel weight in the gap which lies between the switch and the ground. By simply rotating the switch on and off you can lift the weight up and down with less energy than it takes to lift the weight by hand.
