Cautions

Use the Switch within the specified Voltage rating. Using the Switch outside of the rated values will not only shorten its durability but may cause heat generation or fire damage. When turning the power ON or OFF, use the rated voltage and current.

●Degree of Protection

Do not use the Switch underwater.
The Switch was tested and found to meet the conditions necessary to meet the following standards. The test checks for water intrusion after immersion for a specified time period, not for switching operation underwater.
JIS C0920: Degrees of protection provided by enclosures of electrical apparatus (IP Code)
IEC 60529: Degrees of protection provided by enclosures (IP Code)
Degree of protection: IP67(check water intrusion after immersion for 30 min. submerged 1m underwater)

●Protection Against Chemicals

Prevent the Switch from coming into contact with oil or chemicals.
Otherwise, damage to or deterioration of Switch materials may result.


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.
•Use M4 mounting screws with plane washers or spring washers to securely mount the Switch. Tighten the screws to a torque of 1.18 to1.47 Nm {12 to 15 kgfcm}.

●Switch Mounting

When mounting the Switch, do not apply force to the actuator in any direction other than its operating direction.

●Operation

Make sure that the switching object is perfectly separated from the actuator when the switch is not operated and the actuator is pressed appropriately by the switching object when the switch is operated. The switching object must not move beyond its opera- tional limit position, otherwise the Switch may be damaged.
Install the switching object so that its moving direction is the same as that of the actuator.

●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.
•The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% (λ60).
(JIS C5003)
The equation, λ60=0.5×10-6/operations, indicates that the estimated malfunction rate is less than operations with a reliability level of 60%.
