25% - 100% of a spring-loaded pin’s maximum stroke capability.  This is the range of compression a spring-loaded contact may operate in. There are some products that may fall outside this range due to specific design characteristics.  Note that at compression less than mid stroke the electrical and mechanical performance may not meet the stated specifications.  Using spring-loaded contacts at maximum stroke there is a risk of over compression due to tolerance variation which may lead to damage of spring-loaded components and reduced mechanical life.
