Switch Operation
Note: An inductive load causes a problem especially in DC circuitry.
Mechanical Conditions for Switch Selection
Electrical Characteristics for Switch Selection
Electrical Conditions
The Switch in actual operation may cause accidents that cannot be
foreseen from the design stage. Therefore, the Switch must be
practically tested before actual use.
When testing the Switch, be sure to apply the actual load
conditions together with the actual operating environment.
All the performance ratings in this catalog are provided under the
following conditions unless otherwise specified.
Inductive load:A minimum power factor of 0.4 (AC) or a
Lamp load:
Motor load:
1. Ambient temperature: 5 C to 35 C
2. Ambient humidity:
An Actuator suitable for the operating method must be selected.
Ask your OMRON representative for details.
Check the operating speed and switching frequency.
1. If the operating speed is extremely low, switching of the
2. If the operating speed is extremely high, the Switch may break
Do not impose excessive force on the Actuator, otherwise the
Actuator may become damaged or not operate correctly.
Make sure that the stroke is set within the suitable range specified
for the model, or otherwise the Switch may break.
The switching load capacity of the Switch greatly varies between
AC and DC. Always be sure to apply the rated load. The control
capacity will drastically drop if it is a DC load. This is because a DC
load has no current zero-cross point, unlike an AC load. Therefore,
if an arc is generated, it may continue comparatively for a long
time. Furthermore, the current direction is always the same, which
results in contact relocation, whereby the contacts easily stick to
each other and do not separate when the surfaces of the contacts
are uneven.
movable contact will become unstable, thus resulting in
incorrect contact or contact welding.
due to shock. If the switching frequency is high, the switching of
the contacts cannot keep up with the switching frequency. Make
sure that the switching frequency is within the rated switching
frequency.
Therefore, it is essential to know the time constants (L/R) of the
load.

Connections
Power Connection Examples
(Connection of Different Polarities)
Connect the load to the same polarities.
If the load is inductive, counter-electromotive voltage will be
generated. The higher the voltage is, the higher the generated
energy will be, which will increase the abrasion of the contacts and
contact relocation load conditions. Be sure to use the Switch within
the rated conditions.
If the load is a minute voltage or current load, use a Switch
designed for minute loads. The reliability of silver-plated contacts,
which are used by standard Switches, will be insufficient if the load
is a minute voltage or current load.
With a Za contact form, do not contact a single Switch to two power
supplies that are different in polarity or type.
Do not use a circuit that will short-circuit if a fault occurs, otherwise
the charged part may melt and break off.
Application of Switch to a Low-voltage, Low-current Electronic
Circuit.
1. If bouncing or chattering of the contacts results and causes
2. Conventional silver-plated contacts are not suitable for this
3. The contacts of the Switch used for an emergency stop must be
To protect the Switch from damage due to short-circuits, be sure to
connect in series a quick-response fuse with a breaking current 1.5
to 2 times larger than the rated current to the Switch. When
complying with EN certified ratings, use a 10-A IEC 60269-
compliant gI or gG fuse.

problems, take the following countermeasures.
(a) Insert an integral circuit.
(b) Suppress the generation of pulses from the contact bouncing
application, in which particularly high reliability is required. Use
gold-plated contacts, which are ideal for handling minute
voltage or current loads.
