Electrical life
The selection of the optimal contact material has great in?uence on the
operating life. The electrical life test is conducted at rated voltage, rated
current and resistive load at 23 °C ambient temperature. The lower the
electrical current, the longer the electrical life – under some circumstances
it may even equal the switch’s mechanical life.
Please note:
For switching loads which deviate from the values speci?ed in the cata-
logue, we recommend that you discuss the issues involved with Cherry.
This is especially important if you are using other loads as linear resis-
tances. These can be electrical circuits with inductive resistances (mo-
tors), capacitive resistances (condensers) or lamp loads. To ensure that
a switch reaches the maximum of its electrical operating life, the switch
should not be subjected to pressure in its rest position (pre-stressed)
and at least 50 % of the available overtravel must be used. Operating life
speci?cations for direct current loads are available on request. Where
higher switching capacities are involved, we recommend the use of fuses
to provide protection against arcing.
Please note:
Since the operating life of a snap switch depends on a number of factors,
we recommend that ?eld trials be performed in order to establish the likely
electrical life of a switch in a given application. This is especially recom-
Vibration and
shock resistance
Snap switches are naturally fairly resistant to shocks and vibrations thanks
to their minimal mass of moving parts. They are at their most resistant
when the actuator is in the rest position or end position, when vibration
resistance is as high as 5 g at 20 – 200 Hz while shock resistance attains
50 g (6 ms).
Please note:
Snap switches are more susceptible to vibrations at the switching point
and at the release point. In certain conditions, this could result in transient
make or break contacts (bouncing) to the detriment of
the switch‘s operating life. This is why snap switches which are regularly
exposed to vibration should, wherever possible, not be actuated slowly.
Electric strength
The electric strength of our snap switches – in the case of models suited
for mains voltages – exceeds 1500 V AC between conducting parts and the
earth and 750 V AC between the terminals (open contacts) measured over
a period of one minute at an ambient temperature of 23 °C ± 5 °C, relative
humidity of < 70 % and normal atmospheric pressure.
mended when the application deviates considerably from the test condi-
tions described above. Our specialists are always ready to provide you with
more advice regarding possible solutions for your particular application.
Behaviour at
different temperatures
Depending on the model, the operating temperatures of our switches range
from -25 to +70 °C and -40 to +150 °C. If you attempt to use a switch at
operating temperatures either above or below those recommended for your
particular model, the switch‘s material properties will change and
its reliability will be affected. Where switch model codes start with “T”
(e.g. 40T125 in compliance with EN 61058), the switches involved have
been approved for use at the corresponding temperatures.
