●Degree of Protection

•Do not use this product in water.
Although this models satisfy the test conditions for the standard given below, this test is to check the ingress of water into the switch enclosure after submerging the Switch in water for a given time. Satisfying this test condition does not mean that the Switch can be used in water.

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 1 m underwater)

•Do not operate the Switch when it is exposed to water spray, or when water drops adhere to the Switch surface, or during sudden temperature changes, otherwise water may intrude into the interior of the Switch due to a suction effect.
•Prevent the Switch from coming into contact with oil and chemicals.Otherwise, damage to or deterioration of Switch materials may result.
•Do not use the Switch in areas where it is exposed to silicon adhesives, oil, or grease, otherwise faulty contact may result due to the generation of silicon oxide.
•The environment-resistant performance of the switch differs depending on operating loads, ambient atmospheres, and installation conditions, etc. Please perform an operating test of the switch in advance under actual usage conditions.


•Connecting to Solder Terminals
When soldering the lead wire to the terminal, first insert the lead wire conductor through the terminal hole and then conduct soldering.
Complete the soldering at the iron tip temperature between 350 to 400°C within 3 seconds, and do not apply any external force for 1 minute after soldering. Soldering at a excessively high temperature or soldering for more than 3 s may deteriorate the characteristics of the Switch.
•Connecting to Quick-connect Terminals
Wire the quick-connect terminals (#110) with receptacles. Insert the terminals straight into the receptacles. Applying excessive external force laterally may cause deformation of terminals and may damage the housings.
•Connecting to PCB terminals
When using automatic soldering baths, we recommend soldering at 260±5°C within 5 seconds. Make sure that the liquid surface of the solder does not flow over the edge of the board.
When soldering terminals manually, complete the soldering at the iron tip temperature between 350 to 400°C within 3 seconds, and do not apply any external force for 1 minute after soldering. When applying solder, keep the solder away from the case of the Switch and do not allow solder or flux to flow into the case.

Correct Use


•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 M2.3 mounting screws with plane washers or spring washers to securely mount the Switch. Tighten the screws to a torque of 0.23 to 0.26 Nm {2.3 to 2.7 kgfcm}. Exceeding the specified torgue may result in deterioration of the sealing or damage. Mount the Switch onto a flat surface. Mounting on an uneven sur- face may cause deformation of the Switch, resulting in faulty oper- ation 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 cov- ered with a rubber cap, applying a force from lateral directions may cause damage to the plunger or reduction in the sealing capability.


•Do not handle the Switch in a way that may cause damage to the sealing rubber.
•When handling the Switch, ensure that uneven pressure or, as shown in the following diagram, pressure in a direction other than the operating direction is not applied to the Actuator, otherwise the Actuator or Switch may be damaged, or durability may be decreased.

●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.

●Using Micro Loads

•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 following operating range, if inrush current occurs when the contact is opened or closed, it may increase the contact wear and so decrease durability. Therefore, insert a contact protection circuit where necessary. The N-level reference value applies for the minimum applicable load.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 1/ 2,000,000 operations with a reliability level of 60%.
