Looking at Electromechanical Endurance

A common reliability acronym that applies to all types of components and subassemblies is MTBF, Mean Time Between Failure. If you’re an engineer concerned about the reliability of your switch in a hostile, demanding operational environment, then you’re worried about a type of rating called electromechanical endurance (EE). Electromechanical endurance is usually defined in terms of how many switching operations can be performed under certain conditions before failure. These numbers are affected by a number of parameters
