ASTM F2592-10

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).

1.2 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.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
