Precautions
Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide,
“Snap Action Switches, Technical Information” for correct use.
■ Correct Use
Mounting
Turn OFF the power supply before mounting or removing the Switch,
wiring, or performing maintenance or inspection. Failure to do so may
result in electric shock or burning.
Mount the Switch onto a flat surface. Mounting on an uneven surface
may cause deformation of the Switch, resulting in faulty operation or
damage.
Operating Body
Use an operating body with low frictional resistance and of a shape
that will not interfere with the sealing rubber, otherwise the plunger
may be damaged or the sealing may deteriorate.
With the pin plunger models, set the Switch so that the plunger can
be pushed in from directly above. Since the plunger is covered with a
rubber cap, applying a force from lateral directions may cause dam-
age to the plunger or reduction in the sealing capability
.

Handling
Do not handle the Switch in a way that may cause damage to the
sealing rubber. When handling the Switch, ensure that uneven pres-
sure or, as shown in the following diagram, pressure in a direction
other than the operating direction is not applied to the Actuator, oth-
erwise the Actuator or Switch may be damaged, or durability may be
decreased.
Operating Stroke Setting
Set the operating stroke so that the actuator is completely disen-
gaged when the switch is in the free position (FP), and is pushed to a
point between 60% and 90% of the OT distance after the switch is
operated.
Insufficient or excessive pushing of the actuator may result in
decreased switch durability or damage to the switch.
Using Micro Loads
Using a model for ordinary loads to switch microloads may result in
faulty operation. Instead, use the models that are designed for
microloads and that operate in the following range;
0.16mA

26mA 100mA

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, then contact wear may
increase and so decrease the service life. Therefore, insert a contact
protection circuit where necessary.
Wiring Molded Lead Wire Models
When wiring molded lead wire models, ensure that there is no weight
on the wire or that there are no sharp bends near the parts where the
wire is drawn out. Otherwise, damage to the Switch or deterioration
in the sealing may result.
