Power Windows Switch lifts automobile windows that can be raised and lowered by depressing the switch button, as opposed to using a hand-turned crank handle.

Power windows are usually inoperable when the car is not running as the electrical system is not "live" once the ignition has been turned off. The Hydro-Lectric system; however, could lower the windows at rest, since pressure from the hydraulic system was merely released to lower the window. Raising the windows required the pump to operate (at a fairly high noise level) and introduce pressure at each cylinder. These hydraulic systems also required pressure lines to each cylinder (door, seat and top) and tended to leak.

Power windows or electric windows (American English) as well as electric or power window lifts (British English) are automobile windows which can be raised and lowered by depressing a button or switch, as opposed to using a hand-turned crank handle.

Power windows have come under some scrutiny after several fatal accidents in which children's necks have become trapped, leading to suffocation. Some designs place the switch in a location on a hand rest where it can be accidentally triggered by a child climbing to place his or her head out of the window. To prevent this, many vehicles feature a driver-controlled lockout switch, preventing rear-seat passengers (usually smaller children) from accidentally triggering the switches. This also prevents children from using them as toys and pets riding with their heads out windows from activating the power window switch.
