●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.
• When mouting with screw, use M3 mounting screw with plane
washers or spring washers to securely mount the Switch.
Tighten the screws to a torque of 0.27 to 0.29 N·m {28 to
30 gf}. Exceeding the specified torque may result in
deterioration of the sealing or damage.
• Secure the posts by thermal caulking or by pressing into an
attached device. When pressed into an attached device,
provide guides on the opposite ends of the posts to ensure
that they do not fall out or rattle.
●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.
●Handling
• Do not handle the Switch in a way that may cause damage to
the sealing rubber.
• When handling the Switch, ensure that pressure is not applied
to the posts in the directions shown in the following diagram.
Also, ensure that uneven pressure or pressure in a direction
other than the operating direction is not applied to the Actuator
as shown in the following diagram. Otherwise, the post,
Actuator, or Switch may be damaged, or the durability may be
reduced.
●Using Micro Loads
• Even when using micro load models within the operating
range shown below, if inrush/surge current occurs, it may
increase the contact wear and so decrease durability.
Therefore, insert a contact protection circuit where necessary.
