Glossary
CCW—Counterclockwise only (for lever types).
CW—Clockwise only (for lever types).
Differential—The movement differential or differential is the distance or angle from the operating
position to the releasing position.
Free or normal position—Free or normal position is the initial position of the actuator when there is
no external force (other than gravity) applied on the actuator.
Neutral position—Lever operated switch with a minimum of two contacts. One contact changes
state only when lever moves CW. The second contact changes state only when the lever moves
CCW. (The center position is the free position.)
Operating position—Operating position is the position of the actuator at which the contacts change
state.
Overtravel—Overtravel is the distance or angle through which the actuator moves when traveling
from the operating position to the overtravel limit position.
Pre-travel—Pre-travel is the distance or angle through which the actuator moves from the free
position to the position at which the contacts change state, the operating position.
Release position—Release position is that position of the actuator at which the contacts change
state from the operated contact position to the normal contact position.
Release torque—Release torque is the value to which the torque on the actuator must be reduced
to allow the contacts to change state from the operated position to the normal contact position.
Actuator-lever—An actuator is the mechanism of the switch or enclosure which, when moved as
intended, will operate the contacts.
Maintained contact limit switch—A maintained contact limit switch is a switch which remains in a
given condition until actuated to another condition, which is also maintained until further actuation.
Momentary contact limit switch—A momentary contact limit switch is a switch which returns from
the operated condition to its free or normal circuit condition when the actuating force is removed.
N.C.—Normally closed contact, when the switch mechanism is at its free or normal position.
N.O.—Normally open contact, when the switch mechanism is at its free or normal position.
Operating torque—Operating torque (force) is the minimum torque (force) value which must be
applied to the actuator to cause the contacts to change state.
Overtravel limit position—Overtravel limit position is that position of the actuator beyond which
further overtravel would cause damage to the switch or actuator.
Repeatability—Repeatability is the ability to consistently maintain the original operating
characteristics. Measured by the difference between the operating position of a new switch and of
the same after 1 million operations.
Total travel—Total travel is the sum of the pre-travel and overtravel.
Travel—Movement of the actuator from its free or normal position when force is applied. (See pre-
travel and over travel.)
