Abstract
A power window switch circuit, even if soaked, prevents windows from opening or closing unintentionally. A DOWN switch ( ) and an UP switch ( ) each include a first fixed contact (DN , UP ) connected with a power supply, a second fixed contact (DN , UP ) grounded, and movable contacts ( ) for selectively connects either the first or second fixed contact with the first terminal of corresponding relay coils ( ). A transistor (TR ) responsive to a soak signal is connected between the ground and the second fixed contacts (DN , UP ) of the UP and DOWN switches. The second terminals of the first and second relay coils are grounded through their respective transistors. When a soak is detected, a soak detector ( ) supplies a soak signal to the transistors.
