Abstract
A power window apparatus for a vehicle, which has an emergency switch being capable of cutting off a power-window-closing control switch element conjointly with the operation of a switch for opening the power window and has a contactor sliding between normally closed contacts and normally open contacts provided in the form of electrode patterns on a printed circuit board, whereon electrodes extend over the contactor sliding area and a entire surface of the board except the contactor sliding area is covered with a coating of waterproof resin. The emergency switch can eliminate an abnormal simultaneous energization of both the window-opening and closing relays in an accident (such as the vehicle sinking into water) by maintaining the conducting state of the normally open contact even if the exposed portions of the electrode patterns are partly damaged by electrolysis of material.
