These Mechanical Switches being used in yester years have very little merit and served the purpose when the requirement was not stringent. As they rely on large impacts or inertia (both acceleration): they do not respond to gradual increase in vibrations. Nuisance tripping during start-up is an usual problem. Further, sensitivity adjustment is too ambiguous to offer any meaningful translation. Read more...
