Snap Action Switches, also known as micro switches are a kind of momentary contact switch. Theses 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 switches are used 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.
