Mount the rubber boot so that the protrusion at the bottom surface of the opera-
tor fits with the recess on the operator, placing the rubber boot all around the
operator sleeve.
Make sure that the protrusion on the rubber boot and the recess on the operator
fits correctly, otherwise, the waterproof and dustproof characteristics are not
ensured.

Maintained Pushbuttons
Do not replace the buttons when the pushbutton is in the maintained posi-
tion. Replacing the button in the maintained position may damage the internal
mechanism. Also, do not remove the contact block with the button in the main-
tained position. The contact may not operate properly when the contact block is
remounted.
Pushbuttons and Illuminated Pushbuttons with Switch Guard
Do not apply force to the switch guard when the switch guard is not attached to
a panel. When opening the switch guard, do not open more than 180°. The hinge
may break.
Selector Switches
When turning the operator or key, make sure that they are turned to the correct
position.
Selector Switches with Key
Observe the following instructions to prevent malfunction or damage.
• Do not remove the key from any key retained position.
• In addition to the standard key (key number 0H), six other key numbers are
available. Use a key of the matching number with the key cylinder. The stan-
dard key does not have a key number indication.
• Keys are available in two types.
Key numbers 0H (standard), 1H, and 2H are reversible keys which can be
inserted in two ways.
Key numbers 3H, 4H, 5H, and 6H are non-reversible keys. Make sure of cor-
rect insertion direction.
