Main task
The microswitch is used to determine whether the seat backrest is in the upright position.
Type
The switch is of the normally open type. In non-activated position (backrest in normal position, locked in upright position) the switch is open. When the
backrest is folded forwards, the switch closes. The resistors for diagnosis are integrated in the switch.
Connect
Switch pin 3 is grounded to grounding point G33P for 741FL and G34P for 741FR. Switch pin 2 is connected to REC (701) pin 8 for 741FL and pin 7
for 741FR. When the switch is open, the voltage is about 5 V on pins 7 and 8. When the switch is closed, the voltage is about 3.5 V.
