Depending on the motor specs, stalling a motor isn't necessarily a bad thing
for the motor. One of the favorite switch machines for model railroads (the
device that you connect to the turnouts to move them) uses a stall motor for

the turnout the other way, you reverse power. Totally simple - two wires for
hookup, and no internal contacts or switches that can go bad. You can leave
it in the stalled position all day long.
As I said, it depends on the motor. So don't do this with your 9V Lego
Technic motor.
