A Snap Action Switch is a type of momentary contact micro switch which operates at rapid speed as it takes very little force or stimulus to operate. These are highly sensitive switches that respond to very small movements and can rapidly change from one contact position to the other. The BZ series standard basic micro switches are for simple or precision on/off application needs. They are generally used in irrigation systems, semi-trailer trucks, timing devices, office equipment, tests instruments, medical and dental equipment's, HVAC equipment, manually operated devices, and valves.
