How long does a basic switch last?

Answer
Basic switches have electrical life (electrical durability) and mechanical life (mechanical durability).
Explanation
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)

Q
What may have caused a basic switch failure?
- A
Failures of a basic switch may be caused by the following two reasons:
1. Failures related to electrical characteristics: contact failure, malfunction, contact welding, insulation degradation
2. Failures related to mechanical characteristics: operating failure, external damage

Q
How do I properly choose between a basic switch and a sensor?
- A
Basic switches and sensors are both used for detection of an object (workpiece). A basic switch has a simple structure that helps to save energy and directly opens and closes both DC and AC circuit by the contacts. Its snap-action mechanism creates a click feeling that is required for some devices (e.g. computer mouse).

Q
What is the basic switch failure rate?
- A
The failure rate of the basic switch is the contact reliability test data under a microload. For our basic switches, the N level is used as a reference value.
For high-capacity loads, the number of electrical switching is guaranteed.
