4.3 Dismantling the moving transition contacts
Dismantling of the moving transition contacts should be
carried out according to Figs. 20 and 21.
The transition contacts are held by a common shaft 4 going
through all the contacts.
The shaft 4 is locked with two split pins (Fig. 21). Remove
the split pins and punch out the shaft with a 5 mm mandrel
of brass and take care of the springs, washers and contacts
when the mandrel is pulled out.
The springs in view A – A, are loosened in the following way:
Punch out the locking pin in one end of the pin with a 2 mm
mandrel. Thereafter the spring holder can be loosened and
the contacts with springs can be removed. Take care of the
pin.
Repeat the above procedure on the other side of the diverter
switch.
