Please note:
ZF snap switches should only be installed by trained
staff . Generally, adherence to the required air gap
andcreepage distance must be ensured with suitable
measures. These must also be adhered to for lines
connected tothe switch.
If installation is to occur on a conductive surface, insulat-
ing panels must be used. Under some circumstances,
their use is also required between switches installed
alongside one another and plug-in connections. Switches
can be installed in any position. Power transmission to
the connections of the switch is not permitted. When
fastening with screws, screws with a co-planar contact
surface must be used. (e.g. in accordance with DIN 84,
DIN 912). Smooth, solid surfaces are suitable for installa-
tion. Exceeding of the following tightening torque values
is not permissible. We recommend trial installations.
Ifyou wish to install your switches using coupling pins,
wewould be happy to advise you on suitable parameters.
If components are likely to be subjected to vibrations,
weadvise you to take additional measures to secure
them. With solder connections, the product-specifi c
solder recommendations must be heeded in order to
prevent damage or destruction of the switches.
Cleaning agents and solvents in proximity to the switches
can impair their function, especially in case of watertight
models. When using greases (especially mineral oil-based
ones), we recommend consultation with ZF. The switch-
ing action may be initiated by a force acting vertically on
the actuator, or by an angled actuation lever.
ASSEMBLY AND INSTALLATION
Example:
max. 30
ϒ
The angle of the lever in relation to the top of the switch
housing should not exceed 30°. The precise angle will
also depend on the actuating speed, combination of
materials, surface characteristics and so on. In case of
auxil iary actuators with rollers or simulated rollers, steps
should be taken to ensure that the lever does not impede
its own action. This means that the direction of actuation
should be away from the actuator‘s mounting point
towards the roller, and the angle of actuation should
beadjusted to allow for the geometry of the actuation
system. We would always recommend a preliminary
discussion with ZF.
The actuator may not be pre-stressed when at rest.
Whenactuated, the switch should travel well beyond the
switching point. for at least 50% of the predefi ned over-
travel, in order to ensure that full contact is made. It is
quite unacceptable for the switch to exceed the specifi ed
overtravel or end position. Using the switch as a mechan-
ical end stop should be avoided. A high-impact actuation
of the switch can have a negative eff ect on the switch’s
mechanical life.

Materials
For our standard switches, we use high-quality, cadmium-
free plastics which are optimized for the intended appli-
cation. As a rule, we seek to avoid the use of toxic or
hazardous materials. You can fi nd out more about our
materials policy by consulting our hazardous substances
exclusion list.
Behaviour of materials in fi re
Insulating materials which are directly connected to
electrically conductive parts are classifi ed according to
their degree of fl ammability. Most of the materials we
useto manufacture housing are self-extinguishing and
categorised under the UL 94 VO standard.
Proof tracking index
Most of the insulating materials we use in our snap
switches have a proof tracking index of PTI 250 (PTI 300,
e.g. D4) or PTI 175 (PTI 250, e.g. DB, DC). This means
t
hat they are capable of 50 drops of test fl uid at a tes
t
voltage of 250 V without producing any leakage current
(IEC 60112).
RoHS
Switches without leads already conform to RoHS.
Switches with leads are available in RoHS-conforming
models on request. In case of further processing with
lead-free soldering, the product-specifi c solder recom-
mendations must be heeded.
Glow wire test

IEC60335-1 at 850°C and GWIT at 775°C or alter -

MATERIALS AND CONTACT RESISTANCE
Contact resistance
The contact resistance of snap switches is composed
ofthe contact resistance and the resistance of the
conductive parts. It depends primarily on the construc-
tion and the contact material. The contact resistance
ofsilver contacts is max. 100 mΩ, of gold contacts
max.50 mΩ when they are new.
Insulation resistance
The insulation resistance between the conductive parts
ofour snap switches and a conductive underlay or
between the open contacts exceeds 10 MΩ when they
arenew, measured over a period of one minute at room
temperature with 500 V DC.
Caution:
Humidity and soiling can decrease the insulation
resistance.

LEXICON
Remark
ENEC is the abbreviation for “European Norms Electrical
Certifi cation”. The ENEC mark is a common European
safety certifi cation mark, based on testing to harmonized
European safety standards and includes also switches for
appliances in accordance with EN 61058.
Degree of protection
Degrees of protection are expressed in terms of compli-
ance with DIN 40050 part 9 and DIN VDE 0470. They
aredesignated by the letters IP followed by two numbers.
The fi rst number indicates the extent to which the
switchis protected against contact with live parts and
the ingress of solid parts; the second number indicates
the extent to which it is protected against the ingress of
water. For the most part, our switches are covered by
thefollowing types of protection.
APPROVALS, MARKINGS AND PROTECTION
IP00 No special protection
IP40 Protected against access solid foreign
objects of 1 mm diameter and greater
IP50 Dust-protected
IP65 Dustproof and protected against fl owing water
IP67 Dustproof and protected against shortterm
immersion
