A Snap Action Switch is a momentary contact micro switch that operates rapidly with minimal force or stimulus. These highly sensitive switches are commonly used in irrigation systems, semi-trailer trucks, timing devices, office equipment, test instruments, medical and dental equipment, HVAC systems, manually operated devices, and valves. The BZ-2RW53-A2 Snap Action Switch from Honeywell features a low operating force and differential travel, ensuring reliable performance. It has a long mechanical lifespan of up to 20 million cycles and includes an elongated mounting hole for easier and more precise installation.
