Application for dual pushbuttons:

Ideal for use as power switches and start/stop switches (available
with I/ON and O/OFF markings on the buttons and a pilot light in
the center).
Interlock type prevents two pushbuttons from being pressed at the
same time, providing the best solution for up/down switches.

• The minimum mounting centers are applicable to switches with one layer of
contact blocks (one to two contact blocks). When two layers of contact blocks
are mounted, determine the minimum mounting centers in consideration of
convenience for wiring.

• When high temperature is expected, take necessary measures such as secur­ing sufcient mounting centers or using a cooling fan.

• When using the safety lever lock, determine the vertical spacing (*6) in con­sideration of convenience for installing and removing the safety lever lock.
(Recommended vertical spacing: 100 mm)
The minimum length of vertical spacing (*6) is 45 mm when safety lever lock
is not used.

• The 3.2 mm recess is for preventing rotation and is not necessary when the

nameplate or anti-rotation ring is not used.

Degree of Protection

Unit IEC 60529

All units except dual pushbutton switches IP65 (*8)
Dual pushbutton switches IP40 (*9)

*8) When using a nameplate with the HW series, IP65 protection degree is

achieved only when nameplates shown on page 37 are used.
(IP40 when other ø22 namplates such as NWA are used)

*9) IP65 protection degree when HW9Z-D7D button cover is used.

Ordering Information

Standard models

• Specify Ordering No. when ordering.

• Specify a button or lens color code in place of ∗.

• Pilot lights, illuminated pushbuttons, and illuminated selector switches have an LED lamp installed.

• Nameplates and accessories for mono-lever switch are ordered separately. See page 37 to 39.

• Color codes for units without LED lamps:
R (red), G (green), A (amber), Y (yellow), W (white), S (blue)
When using a commercially available lamp, choose a lamp with rated voltage 5 to 30V AC/DC and 1W maximum, and with the same base and shape.
Make sure of correct operation before installation. The operation of HW series cannot be guaranteed when a commercially available lamp is used.

Safety Precautions

• Turn off the power to the HW series switches & pilot lights before starting
installation, removal, wiring, maintenance, and starting installation, removing,
wiring, maintenance, and inspection of the products. Failure to turn power off
may cause electrical shocks or re hazard.

• To avoid a burn on your hand, use the lamp holder tool when replacing lamps.

Operating Instructions

Panel Mounting

• Remove the contact block from the operator (for transformer type pilot lights,
remove the transformer from the illumination unit). Remove the locking ring
from the operator (for pilot lights, remove the locking ring from the illuminated
unit). Insert the operator into the panel cut-out from the front. Tighten the lock­ing ring from the back to install the contact block to the operator.

• For wiring, use wires of a proper size to meet the voltage and current require­ments. Tighten the terminal screws to the recommended tightening torque
(see page 51). Failure to tighten terminal screws may cause overheat and re.

• When using a commercially available lamp, choose a lamp with rated voltage
5 to 30V AC/DC and 1W maximum, and with the same base and shape.
Make sure of correct operation before installation. The operation of illuminated
pushbutton switches cannot be guaranteed when a commercially available
lamp is used.

Safety Lever Lock

IDEC strongly recommends using the safety lever lock (HW9Z-LS, yellow) to
ensure that lock lever is locked, or to prevent maintenance personnel from
unlocking contacts during wiring.

Safety Lever Lock

How to install

• Mount the HW series onto the panel, lock the lever, and push in the safety
lever lock.

Spacing in Vertical Direction

• HW series can be installed with a minimum of 50 mm spacing in vertical
direction (mono-lever switch: 70 mm minimum). Be sure to take the space
required for installing/removing the safety lever lock into consideration. When
the spacing is narrower than the recommended value, install the HW series
units in the order of low to high. When removing, do so in the opposite direc­tion.

Notes for Panel Mounting

Locking ring wrench recommended torque

Tighten the bezel to a tightening torque of 2.0 N·m.

Locking ring wrench

Locking ring wrench (MW9Z-T1) can be used to tighten the bezel. Do not use
pliers. Excessive tightening will damage the locking ring.

• To reinstall, place the TOP marking on the operator and the lock lever in
the same direction, and insert the operator into the contact block mounting
adapter. Then turn the locking lever in the opposite direction.

• Install the safety lever lock (yellow) on the lock lever. The safety lever lock
cannot be installed when the lock lever is not upright.

Panel Thickness

HW series can be mounted on a panel with thickness of 0.8 to 6.0 mm. Take the
thickness of nameplate and/or switch guard into consideration.

Replacement of LED Lamps

LED lamps can be replaced by using the lamp holder tool (OR-55) from the front
of the panel, or by removing the contact block from the operator unit. (See page

38 for lamp holder tool.)

How to Remove

To remove, slip the lamp holder tool onto the lamp head lightly. Then push
slightly, and turn the lamp holder tool counterclockwise.

Installing the Rubber Boot for Dual Pushbuttons

When using the HW7D pushbuttons in places where the pushbuttons are subject
to water splash or an excessive amount of dust, make sure to use the HW9Z­D7D rubber boot (IP65) which is ordered separately.
Recombs the rubber gasket pre-installed on the operator, and install the rubber
boot from the front of buttons.

Notes for Installing the Rubber Boot

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 waterproof
and dustproof characteristics are not ensured.

Installing

Install the lens in the recess between the buttons by pressing against the bezel.

Selector Switches

Turn the operator such as knob, lever, and key to each position accurately.
Releasing halfway may cause the operator to return to the former position, or to
get stuck between. On spring return two-way types, the center of operators may
be misaligned slightly.

Key Selector Switches

Insert the key completely before turning. Failure to do so may cause failures.

Close Mounting

When mounting the units closely in a horizontal row on 30 mm centers, use
optional barriers to prevent interconnection between adjoining terminals, and to
increase the creepage distance. The barriers can be attached simply by pressing
them onto the sides of contact blocks.

Use a barrier (HW-VU1) between the contact blocks.

Barrier

Note: Sufcient insulation distance cannot be obtained if barriers are not
installed, or when other barriers such as HW-VG1 is used.

When using transformer type illuminated HW series of 240V AC maximum
closely in a horizontal row on 30 mm centers, insert straight the solid wires or
stranded wires into inside of the terminal screw on the transformer (see gure
below) to prevent short circuit between adjoining terminals.
