button
Slide the latching lever
to the first position,
then press the yellow
button with
an insulated
tool to operate the
contact.
Slide the latching lever
to the second position.
(The contact is now in
the locked position.)
Note:
The latching lever is Red for AC Coil versions and Blue for DC Coil versions.
