How long does a basic switch last?
Basic switches have electrical life (electrical durability) and mechanical life (mechanical durability).
The catalog shows both electrical and mechanical durability. For details, see below.
- 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.
- 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)
