Installing replacement contact and reassembly
1. Place a new reversing neutral stationary contact into
the mounting holes in the contact panel. Place the
contact assembly so that it is in the board but far
enough out so that engagement can be made when
installing the reversing movable contact assembly. See
Figure 64.
2. Insert a standard flat screwdriver between the middle
and top button contacts on the reversing movable
contact assembly and twist to separate. Line up
the movable and stationary contacts and rotate the
movable contact assembly clockwise over the reversing
stationary contact. See Figure 65.
3. Continue to reposition the screwdriver, separate the
button contacts and rotate the reversing movable
contact assembly until the middle button contact is
fully engaged in the center of the reversing stationary
contact blade. See Figure 66.
4. Slide the stationary and movable contact assembly
toward the contact panel. Align the movable contact
assembly so that the reversing movable contact tube
aligns and goes through the hole in the contact panel.
At this point, the stationary contact and movable
contact should be fully engaged with the contact panel.
See Figure 67.
