★3 terminals, applicable to AC DC control circuits.
★Designed to control the movement of a mechanical part.
★Typically utilized in industrial control applications to automatically monitor and indicate whether the travel limits of a particular device have been exceeded.
★High precision mechanism design offering acute operation and long life.
★In snap action contacts, the movement of the actuator applies force to an over center mechanism.
★This mechanism creates a quick change in contact state when the trip point is reached.
★Reversing the motion of the actuator to a given reset point causes the contacts to snap back to their original position.
★Snap action contacts have different trip and reset points.
★The distance between the trip and reset point is called the travel to reset, hysteresis, or differential.
★Finite travel to reset helps to avoid multiple changes of state if the object actuating the switch is subject to vibration.
★Snap action contacts ensure repeatable performance in applications that involve low speed actuators.
★The amount of travel of the contacts is also not dependent on the amount of travel by the actuator.
★The Micro Switch is widely used in appliance, electronic equipment, automatic machine, car electric, etc
