In case there will be a contact damaged we will proceed to change it with a flat screwdriver
pressing down the plastic lever (yellow arrow) and the contact will drop down. After turning
half a round, the small torx socket screw (yellow circle) the button could be separated from the
contact box. If we have to change the button, we must pay attention that the arrow on the
contact box must be in the same position as in the picture below.
When the button is
assembled again, then we turn half a round the torx socket screw and we have finished.

After doing the buttons verification we will proceed to check if the micro-switch is working
properly. We will use the voltmeter and verify that there is no continuity at the open contact of
the switch (yellow marks) and when we trigger the switch (green mark) we should have
continuity. If it happens it means that the switch is ok.
