The two-way switch controlling mirrors
H30 operates electrical motors located in the right and
left electrically-operated door mirrors P60 and P61respectively.
The switch is supplied when the ignition
is switched on (INT/A) by the line for fuse
B27 at pins
7 and 8 for H30, whilst pin 5 is earthed.
Operating the switch in one direction or
the other, sends one of the two motors a positive and an earth signal,
thereby determining the direction of rotation. The motors which
adjust the vertical position are connected to pin 5 of the mirrors
P60 and P61, the motors which adjust the horizontal
positino are connected to pin 3.
According to the selector
position, either the left motors (output signals from pins 1 and
3 of connector B for control
H30) or the right motors
(output signals from pins 2 and 4 of connector B for H30) are connected; the common supply comes out of pin 6 of H30 and is connected to pin 4 of motors P60 and P61.
The switch
H30is
lit up when the ignition is switched on (INT/A).
