About Pushbutton Switches
Narrow Mounting
When mounting the units closely in a horizontal row on
30mm centers, use optional barriers to prevent interconnec-
tion between adjoining terminals. The barriers can be
attached simply by pressing them onto the sides of contact
blocks.
The pushbuttons cannot
be removed or replaced!
Do not attempt to remove
using a flat screwdriver or
pincers, otherwise the
pushbuttons may be dam-
aged.
When mounting transformer
type illuminated units closely
in a horizontal row on 30-mm
centers, insert solid wires or
stranded wires into inside of
the terminal screw on the
transformer (see figure on the
right) to prevent short circuit
between adjoining terminals.

Installation of LED Illuminated Units
When using full voltage type LED illuminated units, provide
protection against electrical noise, if necessary.
Applicable Wiring
The applicable wire size is 2 mm
mm maximum) One or two wires can be connected.
Be sure to use an insulation tube or cover on the crimping
part of the crimping terminal to prevent electrical shocks.
Note: When connecting wires to contact blocks or transformers in
Installing the Rubber Boot
When using the HW7D pushbuttons in places where the
pushbuttons are subjected to water splash or an excessive
amount of dust, make sure to use the HW9Z-D7D rubber
boot (IP65) which is ordered separately.
Remove the gasket from the operator, and install the rubber
boot on the operator. Pull out the seals of the rubber boot
and place them around the operator sleeve as shown. Make
sure that the seals are not twisted or tucked inside and that
the gasket does not remain, otherwise the normal water-
proof and dustproof characteristics are not ensured.
