Micro switches use a snap-action mechanism to achieve rapid and repeatable electrical switching from a relatively small actuator movement. Important design factors include operating force, release force, differential travel, actuator style, contact configuration, and mounting geometry. Consistent snap action helps reduce uncertainty and supports accurate detection of mechanical movement. Housing and terminal construction should provide adequate strength and insulation. These characteristics make micro switches useful for position sensing, safety interlocks, limit detection, and automated control functions. for consistent configuration.
