General-purpose Basic Switch
Z
Best-selling Basic Switch Boasting
High Precision and Wide Variety
• A large switching capacity of 15 A with high repeat accuracy.
• A wide range of variations in contact form for your selection: basic,
split-contact, maintained-contact, and adjustable contact gap types.
• A series of standard models for micro loads is available.
• A series of molded terminal-type models incorporating safety
terminal protective cover is available.
Be sure to read Safety Precautions on page 22 and Safety Precautions
for All Basic Switches.
Model Number Structure
Configuration
•A variety of actuators is available for a wide range of application.
•The contact mechanism of models for micro loads is a crossbar
type with gold-alloy contacts, which ensures highly reliable
operations for micro loads.
•Contact Gap:
H2: 0.20 mm (extra-high-sensitivity)
H: 0.25 mm (high-sensitivity, micro voltage current load)
G: 0.5 mm (standard)
E: 1.8 mm (high-capacity)
F: 1.0 mm (split-contact models)
•These Switches use a rubber boot on the actuator and adhesive fill
between the case and cover to increase resistance to drips.
•Models with drip-proof terminal protective covers and molded
terminals with resin filling are also available.
•This type is identical in construction to the general-purpose basic
switch except that it has two pairs of simultaneous acting contacts
by splitting moving contacts.
•Since the moving contacts are connected to a common terminal,
either parallel or series connection is possible.
•Highly reliable micro load switching is ensured if the model is used
as a twin-contact switch.
•The maintained-contact type has a reset button at the bottom of the
switch case, in addition to the pushbutton (plunger) located on the
opposite side of the reset button. Use these buttons alternately.
•Since the Switch has greater pretravel than overtravel, it is suitable
for use in reversible control circuits, manual reset circuits, safety
limit circuits, and other circuits which are not preferable for
automatic resetting. (For further details, refer to individual
datasheets.)

Safety Precautions
Refer to Safety Precautions for All Basic Switches.
Terminal Connection
When soldering lead wires to the Switch, make sure that the capacity
of the soldering iron is 60 W maximum. Do not take more than 5 s to
solder any part of the Switch. The characteristics of the Switch will
deteriorate if a soldering iron with a capacity of more than 60 W is
applied to any part of the Switch for 5 s or more.
Operation
•Make sure that the switching frequency or speed is within the
specified range.
1.If the switching speed is extremely slow, the contact may not be
switched smoothly, which may result in a contact failure or
contact welding.
2.If the switching speed is extremely fast, switching shock may
damage the Switch soon. If the switching frequency is too high,
the contact may not catch up with the speed.
The rated permissible switching speed and frequency indicate the
switching reliability of the Switch.
The life of a Switch is determined at the specified switching speed.
The life varies with the switching speed and frequency even when
they are within the permissible ranges. In order to determine the
life of a Switch model to be applied to a particular use, it is best to
conduct an appropriate durability test on some samples of the
model under actual conditions.
•Make sure that the actuator travel does not exceed the permissible
OT position. The operating stroke must be set to 70% to 100% of
the rated OT.
Mounting Location
•Do not use the switch alone in atmospheres such as flammable or
explosive gases. Arcing and heat generation associated with
switching may cause fires or explosions.
•Switches are generally not constructed with resistance against
water. Use a protective cover to prevent direct spraying if the switch
is used in locations subject to splashing or spurting oil or water, dust
adhering.
•Install the switch in a location that is not directly subject to debris
and dust from cutting. The actuator and the switch body must be
protected from accumulated cutting debris and dirt.
•Do not use the switch in locations subject to hot water (greater than
60°C) or in water vapor.
•Do not use the switch outside the specified temperature and
atmospheric conditions.
The permissible ambient temperature depends on the model.
(Refer to the specifications in this catalog.) Sudden thermal
changes may cause thermal shock to distort the switch and result
in faults.
•Mount a cover if the switch is to be installed in a location where
worker inattention could result in incorrect operation or accidents.
•Subjecting the switch to continuous vibration or shock may result in
contact failure or faulty operation due to abrasion powder and in
reduced durability. Excessive vibration or shock will cause the
contacts to operate malfunction or become damaged. Mount the
switch in a location that is not subject to vibration or shock and in a
direction that does not subject the switch to resonance.
•If silver contacts are used with relatively low frequency for a long
time or are used with microloads, the sulfide coating produced on
the contact surface will not be broken down and contact faults will
result. Use a microload switch that uses gold contacts.
•Do not use the switch in atmospheres with high humidity or heat or
in harmful gases, such as sulfide gas (H2S, SO2), ammonia gas
(NH3), nitric acid gas (HNO3), or chlorine gas (Cl2). Doing so may
impair functionality, such as with damage due to contacting faults
or corrosion.
•The switch includes contacts. If the switch is used in an atmosphere
with silicon gas, arc energy may cause silicon oxide (SiO2) to
accumulate on the contacts and result in contact failure. If there is
silicon oil, silicon filling, silicon wiring, or other silicon products in the
vicinity of the switch, use a contact protection circuit to limit arcing
and remove the source of the silicon gas.
Mounting
Always make sure that the power is turned OFF before mounting,
removing, or wiring the Switch, or performing maintenance.
Electric shock or burning may occur.
Selecting Models
We recommend using Drip-proof Models (protection equivalent to
IP62) in locations subject to floating dirt and dust. Other models do not
have a protective structure.
Wiring
For wiring, use a wire size that is appropriate for the applied voltage
and the supplied current. When soldering the Switch, make sure that
the capacity of the soldering iron is 60 W maximum. Do not take more
than 5 s to solder any part of the Switch. Using the Switch with
incomplete soldering may result in errors and heat, which may cause
burning. The characteristics of the Switch will deteriorate if a soldering
iron with a capacity of more than 60 W is used or if any part of the
Switch is soldered for 6 s or longer.

Operation
•Make sure that the switching speed and frequency are is within the
specified ranges.
1. If the switching speed is extremely slow, the contacts may not be
switched smoothly, which may result in a contact failure or contact
welding.
2. If the switching speed is extremely fast, switching shock may
damage the Switch prematurely. If the switching frequency is too
high, the contacts may not be able to keep up with the speed.
The rated permissible switching speed and frequency indicate the
switching reliability of the Switch.
The life of a Switch is determined at the specified switching speed.
The life varies with the switching speed and frequency even when
they are within the permissible ranges. Always conduct appropriate
durability tests under actual conditions before using a Switch.
•Make sure that the actuator travel does not exceed the permissible
OT position. The operating stroke must be set to 70% to 100% of
the rated OT.
Panel Mount Switch (Z-15

@
, Z-01

)
•When mounting the panel mount plunger model with screws on a
side surface, be careful of the dog angle and operation speed.
Excessive dog angle or operation speed may damage the Switch.
•When using the panel mount plunger model mounted with screws
on a side surface, be careful not to apply a large shock. Applying a
shock exceeding 1,000 m/s2 may damage the Switch.
•When using the panel mount plunger model mounted with screws
on a side surface, remove the hexagonal nuts from the actuator.
High-sensitivity Switch (Z-15H)/
Extra-high-sensitivity Switch (Z-15H2)
•When using the Switch in a DC circuit, be sure to provide an arc
suppressor as well because the small contact gap of the Switch
may result in contact troubles.
•In an application where a high repeat accuracy is required, limit the
current that flows through the Switch to within 0.1 A. Also, use a
relay to control a high-capacity load if the Switch is connected to
such a load. (In this case, the exciting current of the relay coil is the
load of the Switch.)
•Do not apply a force of 19.6 N or higher to the pin plunger.
•Exercise care that the environment conditions such as temperature
and humidity do not change abruptly.
Micro Load Applicable Range
Using a model for ordinary loads to open or close the contact of a
micro load circuit may result in faulty contact. Use models that operate
in the following range. However, even when using micro load models
within the operating range shown here, if inrush current occurs when
the contact is opened or closed, it may increase contact wear and so
decrease durability. Therefore, insert a contact protection circuit
where necessary.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability level
of 60% (λ 60). The equation, λ 60 = 0.5×10-6/operations indicates that
the estimated malfunction rate is less than 1/2,000,000 operations
with a reliability level of 60%.
Models with Drip-proof Terminal Cover (Z-@A55-B5V)
Wiring
•To attach the Protective Cover to the case, hold the cover in almost
parallel to the case and then push it to the case. If the cover is
pushed diagonally, the rubber packing may slip off, degrading the
sealability of the Switch.
•Use round solderless terminals having the
following dimensions to connect leads to the
terminals. Tighten the screws of terminals to
a torque of 0.78 to 1.18 N·m. Use the
terminal shown below.
•A cable 8.5 to 10.5 mm in diameter can be
applicable to the sealing rubber of the lead outlet of the Switch. A
two-core or three-core VCT cable having a cross-sectional area of
1.25 mm2 is especially suitable for this.
•Use M4 small screws with spring toothed washer are used as the
terminal screws.

Drip-proof Switch (Z-@55)
•The Switch is not perfectly oil-tight; so do not dip it in oil or water.
•The rubber boots are made from weather-resistive chloroprene
rubber.
•Do not use Basic Switches in places with radical changes in
temperature.
•Rubber boots and rubber caps will tend to harden at lower ambient
temperatures. If an Actuator is used in a pressed state for an
extended period of time at low temperatures, it may return slowly or
it may not return at all. OMRON can provide special Actuators for
use at low temperature with rubber boots or rubber caps made of
silicon rubber, which has superior resistance to cold. Ask your
OMRON representative for details.
Split-contact Switch (Z-10F@Y)
The applicable current varies depending on how the contacts are
used. If the Switch is connected in series, the Switch can endure a
current 1.5 to 2 times higher than the current that can be applied in
parallel connection.
Flexible Rod Switch (Z-15@NJ@55, Drip-proof)
•When the rod is fully swung, the Switch may operate when the lever
returns, causing chattering. Use a circuit that compensates for
chattering wherever possible.
•Do not switch the rod to the fullest extent when the Switch is to
break a power circuit because such a practice may cause metal
deposition to occur between the mating contacts of the Switch.
Other Precautions
•Do not apply excessive force with a screwdriver or other tool when
attaching or removing the Protective Cover. Doing so may deform
the Switch.
•The Drip-proof Terminal Protective Cover can be sued only with
Switches with model numbers ending in “-B5V.”
•Only the Terminal Protective Cover is available for maintenance.

application or use of the products.
At the customer's request, OMRON will provide applicable third party certification documents identifying ratings and limitations of use that apply to the

The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
•
Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
•
Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles,

•
Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE

INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.

establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
