*1. The values given above are initial values.
2. The switch contacts can be used for both general and micro loads; however, once a contact has switched a load, it cannot be used with a load of smaller capacity.
The surface of the contact may become rough, which could compromise contact reliability.
*1. This protective structure is based on test methods according to the standard (EN60947-5-1). Please confirm the sealing performance in advance under actual operating environment and usage conditions.
The switch box body is protected against the ingress of dust, water, and similar substances; however, please use it in a location where chips, water, chemicals, etc. will not come into contact with the operation key insertion slot on the head section.
This may cause premature wear, damage, or malfunction.
*2. The durability conditions are based on an ambient temperature of 5 to 35°C and an ambient humidity of 40 to 70% RH.
*3. Do not apply 250 V AC 3 A to more than two circuits.
*4. Please be sure to secure this to ensure safe use.
*5. According to the evaluation method of EN ISO14119.
*6. This value may vary depending on switching frequency, environmental conditions, and reliability level. Please check with the actual load in advance.
