In mechanical engineering, hardware design, and security architecture, latches are categorized into several distinct mechanical types based on their operating mechanism: 1) Gravity or magnetic latches, which hold doors closed using weight or magnetic attraction; 2) Spring bolt latches, featuring a beveled sliding bolt pushed back by a strike plate before snapping into place; 3) Draw latches, designed with a lever mechanism to pull two panels tightly together under tension; and 4) Cam latches, which use a rotating arm or tongue to secure cabinet doors and electrical enclosures. You can verify these mechanical classifications through industrial hardware engineering manuals.
