The left front power window switch (S21s1), right front power window switch (S21s2) and the left rear power window switch (S21s3), right rear power window switch (S21s4)
are designed as pole reversal switches
The polarity of the power supplied to the motors varies (depending on opening direction). In the non-actuated state both motor connections are connected to ground by the switch contacts. This provides an electric braking effect for the motors.
Moreover, the left front power window switch (S21s1), right front power window switch (S21s2) is equipped with an additional contact for the one-touch down feature. The contact sends the switch-on pulse to the all-activity module (AAM, N10) .
