Precautions
■ Correct Use
Mounting Direction
For a switch with an actuator, mount the switch in a direction where
the actuator weight will not be applied to the switch.
Since the switch is designed for a small load, its resetting force is
small. Therefore, resetting failure may occur if unnecessary load is
applied to the switch.
Operation
Keep the operation control completely separate from the actuator of
the switch, and push it down fully when starting operation. Do not dis-
place the operating position of the actuator when machining.
Consult OMRON in advance if the operating speed is to be extremely
slow, or if the pushbutton is to be set somewhere between the free
position and operating position.
Mount pin pushbutton switches so that stroke of the pushbutton and
the stroke of the operating control overlap on a vertical line. The
stroke of the switch, after operation, should be set to 60- 90% that of
standard OT (MIN operation).
Using Microloads
Using a model for ordinary loads to switch microloads may result in
faulty operation. Instead, use the models that are designed for micro-
loads and that operate in the following range;
However, even when using microload models within the operating
range shown above, if inrush current or inductive voltage spikes
occur when the contact is opened or closed, it may increase contact
wear and so decrease the service life. Therefore, insert a contact
protection circuit where necessary.

■ Cautions
Handling
Be careful not to drop the switch. Doing so may cause damage to the
switch’s internal components because it is designed for a small load.
Solder Terminal Connection
Quickly finish the soldering of the lead wire to its terminal. Use a sol-
dering iron rated at 60W and preferably complete the soldering within
5 seconds.
Excess wattage or prolonged heating can deteriorate the characteris-
tics of the switch.
Insulation Distance
When mounting, make sure there is sufficient insulation distance
between the switch and its mounting panel. If it is insufficient, install
an insulation guard or separator. Always install an insulation guard or
separator when mounting the microswitch on a metallic body. Con-
tact your OMRON representative for information about insulation
guards and separators.
Application Environment
Do not use the Switch in locations that are subject to toxic gas, sili-
con, excessive dust, excessive dirt, high temperatures, high humidity,
sudden temperature changes, water splashes, or oil splashes.
Otherwise, damage resulting by faulty contact of the Switch contacts,
corrosion, or other causes, or other functional faults may occur.
Depending on environmental conditions, the switch should be
rechecked about 3 to 6 months after it has been assembled.
