For "elektrikaal migas," it seems like there might be a typo or a misunderstanding. If you meant "electrical switches," their design life can vary greatly depending on the type, quality, and usage conditions. For instance, a high-quality mechanical switch might have a design life of around 100,000 to 1,000,000 cycles.
