What's the difference between Mechanical life and Electrical Life?

Recently we're doing the research of Ailunce FS01 footswitch for PTT, and the words including Mechanical life and Electrical life appear. Do you know what's the difference between Mechanical life and Electrical Life? From the basic definition, mechanical life refers to the hardware wear life of mechanical equipment, while electrical life refers to the time the equipment maintains or basically maintains the original performance. Do you know the difference and connection between them?

For the pedal PTT, its mechanical life refers to the number of cycles of no-load stepping operations that it can withstand before repair or replacement of mechanical parts, while electrical life refers to the fact that the micro switch does not need to be repaired or repaired under specified normal working conditions. The number of load operation cycles for replacement parts. It is obvious from the definition that the electrical life is added to the mechanical life with load requirements, so the electrical life is far less than the mechanical life. For example, the mechanical life of a foot switch is 1 million times, but the electrical life is only 300,000 times.
