The durability (life) of a switch is the number of switching operations that can be performed by the switch before the specified operating characteristics and performance can no longer be achieved.
There are two types of durability (life): mechanical durability and electrical durability.
1. Mechanical Switch Durability (Life)
This is the durability for operation at the specified frequency and stroke test conditions without supplying power to the switch.
2. Electrical Switch Durability (Life)
This is the durability for operation at the specified frequency and stroke test conditions with a load connected and the rated current and voltage applied.
The life of a switch is affected by the load conditions, operating conditions and application environment. Evaluate switch performance under the actual application conditions.
