Snap action (micro) switches use a spring-loaded mechanism to open or close contacts quickly when an actuator reaches a defined travel point\u2014making them common in appliances, automotive controls, industrial equipment, and medical devices. This guide focuses on practical evaluation steps for U.S. and Canadian OEM buyers\u2014specifications, sample qualification, and documentation\u2014not generic marketing claims.
