Power windows today no longer only raise and lower windows--there are also mechanisms in place that automatically raise windows when a key is turned and that keep windows locked for child safety purposes.
Inside the car door is a series of gears attached a large arm and an electric motor. One end of the arm is attached to the bottom of the window, while the other is wider and has grooves so that it operates as a gear. A smaller gear is fit into the arm and both are attached to a motor.

The wiring of electric windows runs throughout the car. Sometimes it's very simple to wire the car, as each window has its own control. However, the driver's side door often has controls for all the windows in a car, which requires the wiring to run throughout the car. This simply involves more wiring and a central control unit that processes the electric signals from each button in the car. Most electric car windows have a feature that stops them from going up when something gets caught in the way. This is a safety feature that keeps people safe, and mainly is intended to stop children from getting hurt should they stick their arms out of a window that is going up. When the window pushes against something, more force is registered and when a certain amount of force is noted, the window automatically stops or goes down.
