Abstract:
A waterproof power window device comprising:a first series circuit containing a first one-circuit two-contact switch and a first relay, said first one-circuit two-contact switch switchable between ground and a car power supply; anda second series circuit containing a second one-circuit two-contact switch and a second relay, said second one-circuit two-contact switch switchable between ground and a car power supply; andwhereinduring operation of said first switch, said first relay is energized such that a corresponding first contact is switched and a motor is rotated in one direction elevating a window, andduring operation of said second switch, said second relay is energized such that a corresponding second contact is switched and said motor is rotated in an opposite direction lowering said window,an end of said first series circuit is connected to a junction between said second switch and said second relay,an end of said second series circuit is connected to a junction between said first switch and said first relay, andsaid first switch and said second switch are connected with said car power supply during operation and connected with ground during non-operation, thus allowing normal operation of said waterproof power window device when said waterproof power window device is submerged in water.
