OPERATING CHARACTERISTICS
Table 3. Operating Characteristics Definitions
Characteristic Description
Differential Travel-DT Plunger or actuator travel from point where contacts “snap-over” to point where they “snap-back.”
Free Position-FP Position of switch plunger or actuator when no external force is applied.
Full Overtravel Force Force required to attain full overtravel of actuator.
Operating Position-OP
Position of switch plunger or actuator at which point contacts snap from normal to operated position. With flex-
ible or adjustable actuators, the operating position is measured from the end of the lever or its maximum length.
Location of operating position measurement shown on mounting dimension drawings.
Operating Force-OF
Amount of force applied to switch plunger or actuator to cause the contact “snap-over.” Note in the case of
adjustable actuators, the force is measured from the maximum length position of the lever.
Overtravel-OT Plunger or actuator travel safely available beyond operating position.
Pretravel-PT Distance or angle traveled in moving plunger or actuator from free position to operating position.
Release Force-RF
Amount of force still applied to switch plunger or actuator at the moment contacts snap from operated position
to non-operated position.
Total Travel Distance from actuator free position to overtravel limit position.
