ASTM F2592 covers the measurement of force displacement characteristics of a membrane switch. ASTM F2592 replaces Test Method F1570 (Tactile Ratio), Test Method F1682 (Travel), Test Method F1597 (Actuation and Contact Force) and Test Method F1997 (Switch Sensitivity). Force displacement hysterisis loop curve can be used in the determination of Actuation Force, Displacement, Contact Force, Return Force, and Tactile Actuating Slope Angle and Tactile Recovery Slope Angle.
