Classification Term Abbreviation Definition
Force Operating Force OF The force required to press the actuator from the free position to the operating position.
Releasing Force RF The force required to move the actuator from the total travel position to the releasing position.
Total Travel Force TTF The force required to move the actuator from the operating position to the total travel position.
Travel Pre Travel PT The travel distance of the actuator from the free position to the operating position.
Over Travel OT The travel distance of the actuator from the operating position to the total travel position.
Total Travel TT The travel distance of the actuator from the free position to the total travel position.
Movement Differential MD The travel distance of the actuator from the operating position to the releasing position.
Position Free Position FP The position of the actuator when not subjected to an external force.
Operating Position OP The position of the actuator at which the moving contact reverses from the free position when external force is applied.
Releasing Position RP The position of the actuator where the movable contact reverses from the operating position to the free position when the external force on the actuator is reduced.
