How long does a basic switch last?

The catalog shows both electrical and mechanical durability. For details, see below.

1. Electrical durability
   The number of times the switch can be operated by connecting the rated load to the contact with the specified operation frequency stroke.
2. Mechanical durability
   Mechanical durability: The number of times the switch can be operated without energizing the contact with the specified operation frequency stroke.

The life of the switch is calculated in such a way as to satisfy the following requirements. If the product is not used within this range, the life (electrical and mechanical durability) may be shorter than the catalog value.

• Operation speed: 1 m/sec max.
• Operation frequency: 30 times/min max.
• Electrical switching below rated current (including inrush)
• Pushing in the operation stroke at 60% to 90% of the OT standard value 80% of OT from the OP point (e.g. the position pushed in 1.2 to 1.8 mm from OP point when OT is 2 mm)
