Combination switch, function - GF82.30-P-2100-04S
The illustration shows the internal circuit of the combination switch (S4) .
The combination switch (S4) has various switch groups for the various function.
All switch positions are read in by the jacket tube module (N80) and their status is transferred as a message to the CAN bus (passenger compartment).
In addition to the contacts the switches also contain resistors for voltage coding. This means that the connector requires only 5 pins for all functions.
Left and right turn signal switch (S4s1):
The left and right turn signal switch (S4s1) has three positions:
- Turn signals off (a2 ),
- Left turn signals (a3 ),
- Right turn signals (a1 ).
Headlamp flasher switch (S4s2)
As long as the headlamp flasher switch (S4s2) is actuated the corresponding contact (S4s2) is closed.
Low beam switch (S4s3)
When the low beam switch (S4s3) is actuated the corresponding contact (S4s3) remains closed as long as the switch is actuated.
Windshield washer system switch (S4s4):
The windshield washer switch (S4s4) has three positions:
- Non-actuated position (b1 ),
- One-touch wipe (b2 ),
- Wash (b3 )
Wipe switch (S4s5):
The wipe switch (S4s5) has four positions:
- Windshield wiper off (c1 ),
- Intermittent wiping (c2 ),
- Slow wiping (c3 ),
- Fast wiping (c4 ).
