car starter motor is a good example of an electromechanical device. When battery current is applied, an electromagnet is charged and overcomes the resistance of a strong spring attached to a lever which forces the starter gear to engage the engine flywheel. The electrical current simultaneously causes the gear to rotate, forcing the flywheel to turn thereby turning over the engine.
