ASTM F2592Measuring the Force-Displacement of a Membrane Switch
1.1 This test method covers the measurement of force displacement characteristics of a membrane switch.
1.1.1 This test method replaces Test Method F1570 (Tactile Ratio). Tactile Actuating Slope Angle and Tactile Recovery Slope Angle better represent the characterization of tactile sensation, previously called “Tactile Ratio” in Test Method F1570.
1.1.2 This test method replaces Test Method F1682 (Travel). 1.1.3 This test method replaces Test Method F1597 (Actuation and Contact Force). 1.1.4 This test method replaces Test Method F1997 (Switch Sensitivity).
