1. Control principle
The electric rear-view mirrorr is controlled by a switch, without any relay. When the L
position is selected, the Nos 2 and 3 circuits form a loop respectively with the internal circuit of
the switch. Take the Y1 direction as an example, when pushing the switch in the Y1 direction, the
switch connects to the power supply from F19 while the power supply connects with the No 2
circuit (with Nos 2 and 3 circuits when the switch is in L position). So, the current flows across the
motor, goes through No 3 circuit and then gets to the ground. Similarly, when the switch is in R
position, the Nos 4 and 5 circuits connect to the corresponding circuit and form a loop.
