Versatile handle selection
Suitable Standard handle types according to the ordering
code configuration tables. Special handles, gang drive
and additional lettering plate selection configurable with
Cam-Web2.
Nose handles (_N or _M)
Nose handles have a degree of protection IP66. Door mounted versions can be snap-on or screw mounted. Snap-on
mounted switches are suitable for 22.5 mm door drilling and
screw mounted switches have a two (OC10) or four (OC25)
hole mounting pattern. For base mounting, the handle can be
fixed directly on the switch or on the enclosure door via shaft.
The standard front plate sizes are 32x32 mm for OC10 and
51x51 mm for OC25. Nose handles are available in black or
gray color.
Extended nose handle (_E or _F)
Extended nose handles are available only for OC25 switches
and are available in black or gray color. The handle has IP66
protection.
Round front ring handles are available in black and gray
colors and have a degree of protection IP66. The ring diameters are 32 mm for OC10 and 39 mm for OC25. These
handles are snap-on mounted, which are for use with
22.5 mm door drilling.

Key operated switches (K_)
The switches are operated with a key instead of a handle.
The degree of protection is IP54. Key operation is available
with 60° spacing, starting at 0° and onwards. They are also
available with 90° spacings, starting at 0° and onwards. It is
possible to idenitfy the positions for key removal in CamWeb2
or standard key-operated switches have the possibility to
remove the key in all positions. Key operated switches are
available only with snap-on mounting, which is for use in a
22.5 mm mounting hole. The standard front plate sizes are
32x32 mm for OC10 and 51x51 mm for OC25.
Extended nose handles can be snap-on or screw mounted.
For base mounting, the handle can be fixed directly on the
switch or on the enclosure door via shaft. Snap-on mounted
switches are suitable for 22.5 mm door drilling and screw
mounted switches are mounted with a four hole pattern. The
standard front plate size is 51x51 mm.
Nose handle, round front ring (PX)
The round front ring replaces the square escutcheon plate
with legend. These types of handles are used in applications
where position indication or engraving is not needed on the
switch.
Key operated switches, round front ring (KX)
The switches are operated with a key instead of a handle and
the round front ring replaces the square escutcheon plate with
legend. These types of handles are used in applications where
position indication or engraving is not needed on the switch.
There are round front rings in black and gray color, with a
diameter of 30 mm (OC10) and 39 mm (OC25). The degree of
protection is IP54.

Modular switch handle with front cover (MN)
This handle is available only for base-mounted OC25 switches
and the handle is mounted directly to the switch. It is light
gray and the degree of protection is IP20. The handle can
be used with standard 45 mm door or cover cutouts and is
suitable for 35 mm dinrail mounting. If 6 contacts or less are
used, the switch depth is consistent with other standard
45 mm components, such as miniature circuit breakers.

Padlockable nose handle (_1 )
Padlockable nose handles are available for OC25 switches
and replace the standard nose handle. They can be snap-on
(22.5 mm hole) or screw mounted (four hole pattern) and are
suitable for use with door or base mounted versions. The handles are available in black, gray or red-yellow. If the red-yellow
version is selected, the handle will be red and the legend
plate will be yellow. They can be used with up to 2 padlocks.
Padlocking is possible every 45° and the padlockable posi-
tions can be specified in CamWeb2. The degree of protection
is IP66.
Round padlockable handle (_3)
Round padlockable handles are available for OC25 switches
and replace the standard nose handle. They can be snap-on
(22.5 mm hole) or screw mounted (four hole pattern) and are
suitable for use with door or base mounted versions. These
handles are available for use with On-Off switches and allow
the switch to be padlocked in the OFF position.
The handles are available in black, gray or red-yellow. They
can be used with up to 3 padlocks. The degree of protection
is IP67.
Key interlocked nose handle (QN)
Key interlocked handles are available on the OC25 with
screw mounting and require an additional clearance hole for
the lock. The operation of the cam switch is interlocked with
a cylinder lock that is available to be located to the right or
below the switch handle. The key can be removed in the
lockable positions, which can be configured with 30° or 45°
spacings in CamWeb2. The standard legend plate size with
this option is 51x51 mm and the degree of protection is IP65.
Extended padlockable nose handle (_2)
Extended padlockable nose handles are available for OC25
switches and replace the standard nose handle. They can be
snap-on (22.5 mm hole) or screw mounted (four hole pattern)
and are suitable for use with door or base mounted versions.
The handles are available in black, gray or red-yellow. If the
red-yellow version is selected, the handle will be red and the
legend plate will be yellow. They can be used with up to 3
padlocks. Padlocking is possible every 45° and the padlock-
able positions can be specified in CamWeb2. The standard
legend plate size with this option is 66x66 mm and the degree
of protection is IP66.
