Glossary

OF-Operating Force: The force applied to the actuator required to operate the switch contacts

RF-Releasing Force: The value to which the force on the actuator must be reduced to allow the contacts to return to the normal position

TTF-Total Travel Force: The force required for the actuator to reach the total travel position from the free position.

PT-Pretravel: The distance or angle through which the actuator moves from the free position to the operating position.

OT-Overtravel: The distance or angle of the actuator movement beyond the operating position.

MD-Movement Difference: The distance or angle from the operating position to the releasing position.

TT-Total Travel: The sum of the pretravel and total over travel expressed as a distance or angle

FP-Free Position: The initial position of the actuator when no external force is applied.

OP-Operating Position: The position of the actuator at which the contacts snap to the operated contact position.

RP-Releasing Position: The position of the actuator at which the contacts snap from the operated contact position to their normal position.

TTP-Total Travel Position: The position of the actuator when it reaches the stopper.
